The attached drawing is intended primarily to illustrate clearly some embodiments Presently preferred plumbing articles falling within the scope of the present invention. By examining thoroughly and with attention drawing by reading the complete description which will follow, the experts in the art siphons drain, connections to the sewer, drain valves and the like and will include that perform other plumbing ware based on apparently different representations carried on the attached drawing and of the description that will follow without departing from the scope of the present invention.

As described above, the present invention relates to collectors or siphon and drain pipes, each manifold comprising: an elbow having top and bottom ends, the upper end being intended to be connected to the basin of a water- [...] ; at least one discharge opening formed in the curved portion of the elbow; a flange positioned relative to the outlet opening to deflect and to move any material discharged in the end of the elbow; also, a vent coupling placed above said flange. The present invention also relates to drain valves each comprising, on the one hand, a valve member including an internal valve seat, the end portion of a pipe fluid supply being disposed within the valve element to be spaced from the valve seat, said terminal portion comprising at least one opening from the interior of that end portion and, on the other hand, a body mounted, to travel, on the end part of the line fluid supply or to mask said opening, said body comprising a valve closure member which is designed to be applied against the valve seat to form a seal.

Perfectly It will be appreciated the true nature of the present invention by examining directly the attached figure. It has shown in Figure I a part of a building 10 comprising a kitchen 12 and a bathroom 14 joined by a common wall 16. In an opening 18 of the wall 16 is arranged a block plumbing 20 heating and plumbing. The latter is preferably preassembled in a manufacturing facility appropriate prior to implantation into a particular building, such as the building 10.

In the building 10, the block plumbing 20 contains a collector or siphon and drain piping 22, made of a material of low cost, or relatively inexpensive, and corrosion resistant, such as a polystyrene, of urea-formaldehyde polymers, or the like, as shown in Figures 2 and 3, for connecting a closet bowl 24, a drain shower 26, a drain 28 for a toilet bowl and a kitchen sink 30 to a conduit 32's the sewer. This structure 22 manifold and siphon is formed to include the that could be called a bend 34 to 90 °, comprising an upper end and a lower end 36 38 joined by a curved central portion 40. The lower end 38 preferably has a cylindrical profile and its dimensions, as indicated in Figures 2 and 3, are such that it fits within a bell-shaped end 42 in the conduit well-the drain 32. The upper end 36 of the manifold 22 and siphon outlet, preferably a terminal flange 44 for receiving a cylindrical extension 46 of the bowl 24 the water-closet.

Inside the siphon drain manifold 22 and three distinct drain lines 48 are mounted so as to open into the interior of the curved portion 40 near the lower end 38 of said connecting portion by means of outlet openings 50. The apertures 50 are all disposed in the same plane and are spaced away from the portion of the curved portion 40 whose radius of curvature is the lowest. Each of the drain pipes 48 has a siphon part 52, having the general shape of a U, which is below the level of its drain opening 50 and in the vicinity of the elbow 34. As shown in Figures 2 and 3, the different drain lines are connected to the drain 48 from the shower from the toilet bowl and of the sink 26,28 and 30 respectively, by ordinary pipe connections 54 along the sides of the block 56 plumbing 20.

A the interior of the header 22 and drain siphon, the material passing of the bowl 25 of the water closet into the elbow 34 cannot pass through the discharge aperture 50 and in portions siphon 52, by means of a flap or flange 58 curved inwardly, which is attached to the central portion of the curved portion 40 so as to extend downward generally toward the center of the curvature of the curvilinear portion 40. Can recognize that the flange 58 extends into the interior of the curvilinear portion 40 only on a distance comparatively low, so as not to intercept the materials exiting the upper end 36 of the elbow 34 along the portion of the curvilinear portion 40 having the the smallest radius of curvature, and that said flange 58 extends only around the upper most portion of the curvilinear part 40.

Above the flange 58 is formed in the curvilinear portion 40 a small chamber 60, which the extreme upper part 62 is above the upper end 36 of the elbow 34. This end 62 is intended to be connected to an air vent pipe by a standard fitting 66. Under the flange 58, below the outlet openings 50, is an inclined wall 67 which extends parallel to the flange 58 along the length of the end of the flange and which terminates in the interior of the lower end 38. Considering the collector 22 and drain siphon, the use of this structure is substantially evident. When connected as shown, the material from the toilet bowl 24 may pass therethrough without obstacle to the conduit's the drain 32, and the flange 58 tends to direct these materials from passing through outlet openings 50 into any one of the parts of the siphon 52. When materials pass 26 by the drain of the shower, the drain 28 of the toilet bowl or the drain of the sink 30, the fluid is collected in a sump portion 52 and, of course, it will pass by the discharge portion 52 in a manner established. These parts siphon will form seals 52 effectively preventing gas from the sewer through the drain 26,28 and 30. Any quantity of this gas will escape through the air vent pipe 64. With this arrangement, the air vent pipe 64 will never be obstructed.

Although is described above the collector 22 and siphon drain about the use of three different scavenge conduits 48, if carefully reviewing the foregoing, the general means of the present invention may be implemented when just a single drain pipe 48 with the manifold 22 and drain siphon and that, if desired, can be by any number of different conduit and siphon drain corresponding to conduits 48 with the siphon drain manifold and in the same manner that the ducts 48 described herein.

The block plumbing 20 incorporated into the building 10 contains a drain valve 70 for regulating the flow rate of water from a supply line 72 into the toilet bowl 24 via an outlet duct 74. During operation of the drain valve 70, the water is stored in a reservoir 76 until the valve 70 is operated to that a water pipe can convey water to the toilet bowl 24.

The drain valve 70 comprises a valve member 78 comprising a housing upper cylindrical 80 includes a cap 82 screwed thereto in 84. The cap 82 supports a relief cylinder 86 extending from its central portion. Inside the cap 82 is an annular valve seat 88, the outer surface 90 has a conical profile. The valve seat 88 extends completely around the inlet of the cylinder 86 by the cap 82. The end of the housing 80 which is remote from the cap 92 82 has a thread onto which is screwed a nut 94 serving to secure said housing to the reservoir 76 in a conventional manner so that the housing 80 is oriented vertically.

The feed duct 72 opens into the housing 80 and includes a terminal portion 96 of uniform cross-section, extending along the axis of the housing 80 in the axis of the cylinder 86. The end portion 96 has a closed end 98 away from the cylinder 86 and spaced from the cap 82. At least one opening 100 is provided in the end portion 96 between its ends; is preferably a plurality of openings 100. The end portion 96 has a conical baffle 102 which diverges outwardly from said portion towards the cap 82 so as to extend around the openings 100. The deflector includes a flat end 104 extending transversely to the axis of the end portion 96, and an inner groove 106, which surrounds the end portion 96 in the direction of that of the ends of the latter which is remote from the closed end 98.

A body 108 having a first end and a second end referenced 110 is referenced 112, is disposed within the valve member 78 so that the end portion 96 extends into an opening 114 from the second end 112. Preferably, the opening 114 has an internal configuration corresponding to that of the end portion 96, so that the latter serves as a guide during movement of the body 108, as described below. The second end 112 of the body 108 is provided with an edge position 116 extending generally from the second end 112 around the opening 114. The end 118 of the flange 116 is contoured to conform to the inner profile of the groove 106 to be received therein when the body 108 is in a specific position. The remaining portion of the second end 112 of the body 108 preferably extends transversely or perpendicular to the axis of the end portion 96, so that the end 112 bears against the end 104 of the deflector 102 when the end 118 is received in the groove 106.

The first end 110 of the body 108 exhibits an external ring 120, forming a projecting flange, the inner wall 122 which has the profile of a truncated cone which can fit against the surface 90 of the valve seat 88 to form a sealed device. The portion of the first end 110 of the body 108 which is housed inside the ring 120 in the form of a surface of revolution 124 having a configuration corresponding more or less to one of a bell having an outer concave surface. The surface 124 results in a flat protrusion 126 which extends in the cylinder 86 when the body 108 is in the position shown in Figure 4.

The body 108 is to be lifted by means of a lever 128 with a ball 180. This rests against a conical seat 182 provided within a threaded cylindrical extension 134, from the cylinder 86 perpendicular to the axis of the cylinder. The ball 130 is normally held so as to be rotatable using a cap 186, ring like, which is screwed onto the extension 134. The cap is preferably used to maintain a flexible annular seal 138 cork, rubber or similar material, against the ball 130 to prevent leakage.

When the drain valve 70 is normally in place, the body 108 is arranged as indicated in Figure 4 to seal the cylinder 86 with respect to the interior of the housing 80 and the tank 76. When water is sent to the drain valve 70 by the supply line 72, it passes as indicated by arrows of Figure 4 into the end portion 96 and extends through the apertures 100 about the second end 112 of the body 108 into the housing 80, and from there it flows upwardly into the reservoir 76.

When the valve 70 is to be used to change the liquid contents within the toilet bowl 24, the lever 128 is pivoted in the direction indicated by the curvilinear arrow range lower right in Figure 4. Therefore, the lever collides with the protrusion 126, thereby to move the surface 124 relative to the surface 90 by a distance comparatively low. As a result, the pressure of the water contained in the housing 80 and into the reservoir 76, and the pressure of water moving in the feed duct 72, cause an annular water current and continuous between the surface 90 and the wall 122. Due to the shape of those surfaces, the current of water impinges on the surface 124 of the first end 110 and causes elevation of the body 108 on the end portion 96 to the point where the ascending is stopped by engagement between the second end 112 against the end of the deflector 102 104. In this position, the end 118 of the flange 116 covers the openings 100 to seal the supply line 72, so that it arrives more water in the housing 80 from the pipe.

During the time the body 108 is spaced from the cap 82, the fluid from the reservoir 76 of the housing 80 and flows past the baffle 102 and along the exterior of the body 108, and into the cylinder 86 from which it exits to sparge the toilet bowl 24. During this water flow, a pressure is exerted on the surface 124 so as to hold the body 108 in the position shown in Figure 5. However, when the reservoir 76 and the housing 80 become empty, the body 108 slides along the end portion 96 to form a tight fitting seal between the wall 122 and the surface 90. Normally, the weight of the body 108 is sufficient to return the lever 128 to its initial position shown in Figure 4. To obtain the mode of operation described above, it is, of course, necessary that the distance between the ends 110 and 112 of the body 108 is greater than the distance between the closed end 98 and the cap 82, and that the opening 114 is sufficiently long for the body 108 can move so as to extend in the deflector 102 and to seal the apertures 100.

The above enables to see that substantially all of the elements of the drain valve 70 may be formed by various relatively inexpensive plastics, such as various types of various qualities or polystyrene, polyurethane, polypropylene or various other different materials. When the various parts of the drain valve 70 are
