VALVE CONTROLLED BY FLUID

A permanent magnet actuated pilot operated valve having a central permanent magnet disposed within an annular axially polarized magnet. The annular magnet is attached to a pressure responsive membrane moveably responsive to a fluid pressure control signal. Movement of the annular permanent magnet effects movement of the central magnet, either by attraction or repulsion depending on whether like or opposite poling is employed. Movement of the central magnet effects opening of a pilot valve which creates a pressure differential which in turn causes a second pressure responsive membrane to move and effect opening of a main valve. Change in the fluid pressure control signal causes the annular magnet to return to its original position thereby effecting reverse movement of the central magnet and closure of the pilot valve. A bleed hole causes pressure equalization across the second membrane and reclosure of the main valve.

A valve for use in a fire extinguishing system comprising a valve member 12 with a predetermined area on its inlet side exposed to the inlet pressure to produce a force tending to open the valve a larger area on its opposite, control side exposed to the pressure in a chamber 20 to produce a force tending to close the valve a passageway 32 through the valve member and a one-way valve 38 in the passageway 32 permitting fluid flow only from the inlet side to the control side of the valve member. The chamber 20 is vented to atmosphere when fire sensors 28 are activated, and the inlet pressure lifts the valve member 12 off its seat 10 to open the valve. The one-way valve 38 prevents unintentional opening of the main valve in the event of the temporary loss of inlet pressure. A weak spring 44 may urge the valve member 12 against seat 10. <IMAGE>

DIAPHRAGM VALVE CONTROLLED BY A PILOT VALVE

Domestic water tap with push button control - permanent magnet is pushed down to open orifice and second push raises magnet

Depressing the button (14) lowers the magnet (29) whose radial projections (30) slide in grooves (26) in the head (11) until free (31). It is then turned by teeth (28) in the button and locks between two grooves. A piston (22), pulled up by magnetic attraction, releases a plunger (21) sealing a flexible diaphragm (20) dividing the delivery chamber in two (18, 19). Water introduced into the upper part (18) through a bypass (15) flows into the outlet (16), the pressure drop allowing the inlet water to raise the diaphragm and discharge. Pressing the button again turns the magnet; it returns and a spring (23) shuts off the water flow.

Flush valve seal handle packing

A toilet flushing device has a body with an inlet and an outlet. There is a valve seat in the body in the flow path between the inlet and the outlet and a valve in the body movable toward and away from the valve seat to control water flow through the toilet flushing device. A handle assembly for causing movement of the valve toward and away from the valve seat includes a socket attached to the body and a handle mounted in the socket for pivotal movement. A plunger is positioned in part within the socket and is in contact with the handle. Pivotal movement of the handle causes axial movement of the plunger with a portion of the plunger being positioned for contact with valve for causing movement thereof. There is a spring for biasing the plunger toward the handle. A bushing is attached to the socket and has a central bore within which the plunger moves. A seal member is attached to the bushing and forms a seal therewith. The seal member has a central passage with the plunger being positioned within this central passage. The seal member has a plurality of spaced inwardly extending circumferential seal lobes which are in sealing contact with the plunger at axially spaced locations thereon. The lobes define at least one recess therebetween and there is lubricant within the at least one recess.

Hydraulic or pneumatic servo-controlled valve - uses permanent magnet and soft iron yoke to open pilot valve

The lower part of the valve has an inlet and outlet and a valve seat which is sealed by a diaphragm. The diaphragm is provided with a small orifice which normally maintains the chamber at inlet pressure. The pilot valve seals the central hole under the load of a spring. A yoke of soft magnetic material is attached to the pilot valve. The upper part of the valve is of non-magnetic material and houses the diaphragm which carries a permanent magnet. When the top diaphragm is depressed, the pressure generated on the lower diaphragm pushes the magnet downwards. This magnet motion attracts the yoke upwards and so opens the pilot valve.

Pulse generator for periodic pneumatic controls

Patent FR2129301A5

Automatic flow control valve with variable set-points

The invention provides a pilot valve apparatus for use in an automatic fluid control system for maintaining pressure downstream from a main control valve between two setpoints irrespective of flow changes through the main control valve. The pilot valve has a flexible pilot diaphragm which moves with a moveable pilot valve member to cooperate with a fixed pilot valve member to control fluid flow through the pilot valve apparatus. The pilot valve controls control pressure acting on the main control valve. An actuator apparatus connected to a body of the pilot valve apparatus has a moveable actuator partition which is exposed to a pressure differential signal reflecting flow through the main control valve. A resilient connector cooperates with the actuator partition and the pilot diaphragm to permit limited relative movement therebetween, and to transfer resilient force to the pilot diaphragm resulting from movement of the actuator partition. This transfer varies location of the moveable pilot valve member with respect to the fixed pilot valve member to vary flow through the pilot valve apparatus, so as to vary control pressure, which in turn controls the main control valve. An adjustable actuator stop can cooperate with the actuator partition to limit movement of the actuator partition. An actuator resilient member can cooperate with the actuator partition to apply a force selectively to the actuator partition to resist displacement thereof.

Variable bleed valve

A valve including an inlet port, an outlet port, an orifice between the ports surrounded by a valve seat, and a valve member supported by a diaphragm above the valve seat. Above the diaphragm the valve includes a chamber connected by a bleed passageway to the inlet port and by a conduit to a pilot valve for selectively venting the chamber. A slidable blocking means or plug is provided responsive to the pressure difference between the chamber and inlet port. The plug closes the bleed passageway when the pressure in the chamber rises close to valve inlet pressure and the plug opens the passageway only when the pressure in the chamber falls to a relatively low value. Thus, with fluid pressure applied at the inlet port, when the pilot valve is opened the bleed passageway remains closed until the pressure in the chamber falls and the valve member moves away from the valve seat. When the pilot valve is closed the bleed passageway remains open until the pressure in the chamber rises high enough to cause closing movement of the valve member. As a result, a pressure pulse having small rise and fall times is provided at the outlet port.
