Abstract: A mixing valve particularly suited for use as a water faucet includes separate levers for selectively delivering an unmixed flow of cold water, an unmixed flow of hot water, and one or more mixed flows of intermediate temperature water. An intermediate temperature flow is obtained by combining separate flow of cold and hot water in a mixing chamber. Temperature selection elements are provided to control the relative proportion of the flow of cold and hot water delivered to the mixing chamber so that any desired intermediate temperature can be selected for the mixed flow delivered from the mixing chamber. Constant temperature of a mixed flow is maintained throughout the available range of flow rates by coordinating the admittance of cold and hot flows to the mixing chamber with respect to the discharge of mixed fluid from the mixing chamber.

Abstract: A faucet manifold according to the invention is adapted to be mounted on a countertop over openings through which access can be had to water-conveying conduits. The manifold includes a cover in the form of a plate overlying the openings. The plate is spaced from the surface of the countertop by a skirt extending downwardly from the periphery of the plate. The plate includes three vertically oriented sleeves. Valve members are disposed in two of the sleeves and a spout assembly is connected to one of the sleeves. Water is directed into the valve-containing sleeves through tubes connected to openings formed in the sleeves. The valve-containing sleeves are connected to the spout-supporting sleeve by tubes connected to additional openings formed in the sleeves. All of the components of the manifold can be manufactured inexpensively, many of them in stamping operations. The invention eliminates the need to form parts in casting operations, thereby significantly reducing manufacturing costs.

Abstract: A closure-assisted valve includes a cartridge insertable into, and removable from, the remainder of the valve structure. The cartridge includes a displaceable piston having an elastomeric sealing member at one end engageable with a flat-surfaced valve seat. At the other end, the piston includes a drive surface against which a rotatable drive member is engaged. In a preferred embodiment, certain relatively movable portions of the cartridge include a cam surface and a cam follower. The cam surface is contoured such that the piston is advanced toward a valve closed position upon rotation of the drive member, but the last portion of piston travel prior to valve closure is only under the influence of gravity and fluid forces. In order to bias the piston toward a valve closed piston, entering fluid is directed around the piston so as to aspirate the piston toward a closed position.

Abstract: An ablution faucet includes a wall-mounted control valve and a flexible conduit having a hand-held control unit at the end thereof. The hand-held control unit includes a body portion from which a nozzle projects, and a lever for controlling the flow of water through the nozzle. The body portion includes a piston which is always urged into engagement with a valve seat by water pressure and a piston-actuating member engageable by the lever. Various alternative embodiments of the piston and piston-actuating member are disclosed. The wall-mounted control valve also includes a piston which is biased to a valve-closed position by water pressure, as well as a vacuum breaker. An alternative embodiment of the invention employs a cable disposed within the hose and connected in valve-actuating relationship between the lever and the wall-mounted control valve.

Abstract: In a wall hydrant, on the inner and outer ends of a wall-penetrating conduit, an inlet connection casting and a discharge casting; a valving member movable axially in an inlet valving bore relative to a seat; a lateral conduit outlet from a discharge casting bore; a shaft structure including key-rotated stem threaded through a plug in the latter bore end and connected axially to shift, upon rotation, the valving member, and also a shaft-carried flange "O"-ring sealable on an interior surface controlling plug-associated exterior draining and air vent openings; the valving and flange seals being spaced, relative to the controlling surface and inlet bore spacing, for conduit drainage and vent opening after inlet closure; a part of the shaft structure upon removal being invertable to serve as a valve seat service tool. Within the hydrant, an anti water backup device.

Abstract: A mixing valve particularly suited for use as a water faucet includes separate finger-operated lever controls for selectively delivering an unmixed flow of cold water, an unmixed flow of hot water, and one or more mixed flows of intermediate temperature water. An intermediate temperature flow is obtained by combining and mixing separate flows of cold and hot water in a mixing chamber. A temperature selection lever is provided for positioning a flow restriction element to control the relative proportion of the flows of cold and hot water delivered to the mixing chamber so that any desired intermediate temperature can be selected for the mixed flow delivered from the mixing chamber. Constant temperature of a mixed flow is maintained throughout the available range of flow rates in part by coordinating the admittance of cold and hot flows to the mixing chamber with respect to the discharge of mixed fluid from the mixing chamber so that suitable back pressure is maintained in the mixing chamber.

Abstract: In a wall hydrant, on the inner and outer ends of a wall-penetrating conduit, an inlet connection casting and a discharge casting; a valving member movable axially in an inlet valving bore relative to a seat; a lateral conduit outlet from a discharge casting bore; a shaft structure including key-rotated stem threaded through a plug in the latter bore end and connected axially to shift, upon rotation, the valving member, and also a shaft-carried flange "O"-ring sealable on an interior surface controlling plug--associated exterior draining and air vent openings; the valving and flange seals being spaced, relative to the controlling surface and inlet bore spacing, for conduit drainage and vent opening after inlet closure; a part of the shaft structure upon removal being invertable to serve as a valve seat service tool. Within the hydrant, an anti water backup device.

Abstract: A valving device for inclusion in a pair of lines delivering hot and cold water to a point of mixed flow use having respective flow valving sections including respective aligned valving members joined as a shuttle unit, secured to and extending through flexible diaphragm means isolating the sections, and longitudinally shiftable to decrease flow area in one section while increasing flow area in the other; each section having a flow constriction as a fixed resistance between the diaphragm means and a respective valved flow space, whereby upon change of the relation of supply pressure and consequent tendency to change flow ratio from a pre-existing relation, the shuttle shifts to null the difference of forces acting thereon in the two sections and thereby re-establish the flow ratio; a hot inlet temperature responsive override being includable.

Abstract: In a wall hydrant, a wall-penetrating straight tubular conduit; a valving member movable axially in and out of sealing engagement with a reduced inlet connection valving bore; a hollow cylindrical end casting on the conduit outer end providing a lateral conduit outlet opening from a discharge bore; a plug in the outer casting end having a threaded aperture with a key-rotated stem threaded therethrough connected with a shaft to axially shift, upon rotation, the valving member moved by the shaft inner end and a shaft-carried flange slideably "O"-ring sealable on an interior surface controlling exterior draining and air vent openings associated with the plug; the valving and flange seals spaced, relative to the controlling surface and inlet bore spacing, for conduit drainage and vent opening after inlet closure; also in combination with the hydrant a wall box, a vacuum breaker and air inlet device including an integral enlargement on the casting outlet, a cap secured thereon with a hose connection as the hydrant

Abstract: A handle-carrying operating plug serving also a valve body-closing bonnet function, having a threaded internal engagement with the body, has a sliding relatively rotatable lost motion connection with an internal valving stem carrying a valving member, whereby the valving member, displaced to open position by plug-rotation in one direction, is permitted to advance in the body from an open position to a closed position under water flow or static pressure or/and spring bias, as the plug moves out upon rotation in the other direction for valve closing, and with a permitted further plug member rotation after valve closing, a drainage passage through the plug opens by relative axial motion of plug and stem; and by further rotation the plug is withdrawable for cleaning of a filter on the outlet side of the valving region in the body, the filter being plug-supported, spring biased to follow the plug to the body mouth, or merely body supported; ensuring a shut off condition when the valve body is opened for cleaning o
