A GAS VALVE

A valve (100) for controlling gas flow for a gas heating which allows, as different embodiments, (1) A gradual and smooth transition from high flow to low flow. This is achieved by a rotatable control means (108) wherein the valve body or control means has a tapering groove (134) on an annular path intersecting with a port to allow variation in flow rate as the control means rotates. (2) The ganging together into modular form of several valve units with the inlet ports forming a common inlet manifold. (3) The control means, at least, is a plastic, eg nylon. (4) The switching to off from either high or low flow is allowed. But the switching from off to on is directly to high flow. The switching from off to on is prevented from going to low flow directly.

VALVES CONTROLLING FLOW

Valves controlling flow of gas or liquid, where compressible material is trapped within a rigid housing to provide a leak-proof seal surrounding an longitudinally movable rigid shaft. Where the shaft has a hollow channel and perpendicular ports to the outer surface, it allows for on and off control and is called a hollow shaft valve. If the shaft has diametric reductions on its outer surface, the valve allows for variable control. Creating a series of hollow shaft valves and variable shaft valves on a single shaft allows multiple functions through a single seal to create a serial shaft valve. The technology also allows for the precise and indexed variable control of fluid flow through a variable shaft valve by having a bayonet style system to precisely actuate orifice size rather than a rotary handle. This arrangement has application in a wide variety of situations including chlorination valves. In the case of automobiles, the valve used to vent fuel in the case of an accident can be triggered ...

Rotary gate valve for hydraulic servo-assisted steering systems

A servo-assisted steering system has a rotary gate valve composed of a rotary distributor (10) forming a single piece with the steering column (3) and a valve bush (20) forming a single piece with a threaded spindle (5). To carry away return oil for each direction of rotation, return bores (11-17) longitudinally arranged one after the other form two adjacent bore rows (9 or 9A). Each bore row (9 or 9A) is associated with a control groove (24 or 22) in the valve bush (20) linked to the working cylinder. The return bore (17) lies between the two bore rows (9 or 9A) and has an unvarying residual cross-section. To control the pressure increase, all return bores have in their active pressure chambers (30 or 31) flat control windows (51-57) of various circumferential lengths. The return cross-section created by the return bores can be changed by a driving piston (60) arranged in a concentric bore (45) of the rotary distributor (10). The driving piston (60) can be adjusted according to a driving speed dependent pressure. The change in cross-section of the bore rows (for example 9) that help control the pressure allows the actuating forces of the steering wheel to be adapted to each driving condition.

Spool valve and method of making the same

A spool valve has a valve body with an elongated cylindrical bore therein. Fluid passageways extend in a radial direction through the valve body and communicate with the interior bore. A peripheral port edge is defined by the intersection of the bore and the passages. A cylindrical valve spool is slidably mounted in the bore to close and open the passageways with respect to the bore. The valve spool has a cylindrical outer surface and at least one planar circular surface with a peripheral metering edge therebetween. The peripheral metering edge has a plurality of tapered notches therein which are adapted at times to overlap the peripheral port edge to permit fluid flow between the bore and the passages. The method of this invention involves creating the notches in the valve spool by positioning a knurling tool at an angle with respect to the peripheral metering edge of the spool, rotating the knurling tool with respect to the spool to permit the spaced longitudinal V-shaped projections of the knurling tool to impress in the spool the desired tapered notches.

The stack forms an inner or outer cylindrical wall, and a cylindrical valve stem is provided which contacts the stack wall. At least one group of discs (101) forms horizontal recesses or flow channels (103) opposite the stem, and other discs have another group of apertures overlapped by those of the first group, all opening of both disc groups being opened to the stack inner or outer cylindrical wall. The disc groups, by being rotated, form radially opposed and/or circumferentially displaced apertures which form channels in which the fluid flows in and out of the thus formed narrowed parts. A device is provided for a vertical movement between the stack and the stem, between closed and epened positions.

Cavitation free throttle valve - with two or more stages of progressively increasing flow area to avoid noise

The valve may have a housing with an inlet and an outlet. A hollow valve piston is movable to admit fluid from the inlet into a cylinder through openings in the wall of the piston and to free openings in the wall of the cylinder for the fluid to pass to the outlet. The openings in the piston are of smaller flow area than those in the cylinder and such that the pressure drop at either holes does not fall below a given value. In this way the substantial pressure drop occuring at a single stage and consequent noise or cavitation are avoided.
