Abstract: The present invention relates to an adjustable valve for a toilet in which the valve remains in a lower setting unless it is activated by the user to a higher setting and automatically returns to the lower setting after flushing the toilet. The amount of water used for each flush is dependent on the water level in the toilet tank. The water level in the tank is set by adjusting the height of the valve assembly. The valve assembly can be activated by the user to raise the height of the valve assembly and maintain the height using a release clip, thereby increasing the amount of water in the tank. When the handle is pressed to flush the toilet, the release clip is pulled back by a chain extending from the handle and the adjustable valve springs back to the lower setting.

Abstract: Leak detector apparatus (40) is provided for use with a toilet inlet valve assembly (12) that includes a float (30) slidable along a vertical post (32), which can be easily installed by a handyman. The leak detector apparatus includes a buoyant body (42) and a mount (44) that pivotally supports the body about a body axis (54) on the float (30). The body has a forward end portion (56) that can engage the post to prevent the float from moving down until a chain device (60) attached to the rear of the body is pulled to pivot the body. The body has a center of buoyancy (80), when immersed in water, which lies forward of the body axis, so when immersed the body urges its forward end portion against the post to prevent the float from moving down. The forward portion of the body can include a metal strip with a sharp edge (74) that "digs" into the inlet valve plastic post. The mount includes a pair of upstanding mount posts (114) that project into air holes (112) on the float.

Abstract: A liquid storage tank overfill prevention assembly that includes an outer housing, an insert that includes fill flow ports, a shut-off sleeve to slowly close off the flow ports and a float member for controlling the sleeve in response to the rise of the stored liquid level. As the product flows through the assembly it is diverted through flow ports in the insert to the inside of the outer body and through the fill pipe installed in the bottom of the valve. As the product level in the tank increases, the float rises and the shut-off sleeve relatively slowly covers or closes the flow ports in the insert. The shut-off is gradual and no hydraulic shock is felt through the valve. For further benefit, the shape of the shut-off sleeve diverts the liquid flow steam through the ports and is shaped to maintain substantial laminar liquid flow until the liquid exits the ports into the housing interior.

Abstract: The present invention discloses a valve which utilises an imbalance of flow induced pressure forces to keep the valve open or closed. The valve has an interior cavity (15) into which an opposite and aligned inlet (12) and outlet (13) open. A bulbous body (16) is located within the cavity and is reciprocally mounted on a spindle (17) which passes through the outlet. Movement of the body increases the flow area at one end of the body and decreases the flow area at the other end of the body. In accordance with Bernoulli's theory this changes the pressures acting on the body (16) giving rise to a net force on the body. A cistern inlet valve (111,211) and cistern (19) are also disclosed.

Abstract: An hydraulically assisted inlet valve is disclosed having a by-pass passage (32) which is permanently open. Preferably the valve has a valve body (13) reciprocally mounted in the inlet (4) and carried by a diaphragm (23). The by-pass passage preferably extends through the valve body (13) to apply inlet pressure to one side of the diaphragm.

Abstract: A tank valve for refilling a toilet tank and simultaneously supplying water to a toilet bowl has a riser, a valve mounted to the riser, a valving chamber in the body of the valve, and a downwardly directed outlet port from the valving chamber. A cuff surrounds the riser. It has a bottom with an aperture to pass the riser, and a peripheral sidewall extending upwardly from the bottom with an upper edge spaced from the body through which water from the outlet port into the cuff flows into the toilet tank. A fill port through the cuff leads by way of a hose to supply water to refill the toilet tank bowl.

The valve body includes a dual sleeve tubular member, the lock means end of which is capable of vertically adjustably engaging with the inlet pipe by the inner circumference of the outer pipe of the tubular member. The upper section above the flange of the inlet pipe forms into an annular retaining part composed of spacings mostly in definite arrangement thereby permitting adjustment of the valve in height in relation to the height of the water tank and regulation of the water level in the tank. The valve arrangement disposed on the top end of the tubular member includes a block the interior of which forms a valve house and a release valve, a rubber valve placed beneath the block and being closable and openable in respect of the opening at the upper end of inner sleeve pipe.

Abstract: A two function tank valve according to this invention includes a vertically oriented supply tube or conduit with an upper opening. A valve seat surrounds the opening, and a valve seal is movable against it and away from it. Water level responsive means determines this valve setting so the valve can be opened to fill the tank, and can be closed when the tank is full.

Abstract: An improved ballcock assembly for a toilet water reservoir which provides quiet reservoir refill operation without requiring a conventional water discharge hush tube. Quiet refill operation is provided by discharging refill water through a plurality of openings which create individual streams of water which flow along the side surfaces of a standpipe having longitudinally extending external ridges or walls. The walls maintain the separation of the individual water streams which cascade down the standpipe surface. The outside surface of the standpipe is preferably tapered outwardly from top to bottom so that the water flows along a tapered surface which reinforces the cascading flow regime. The reduced flow for each stream and the cascading flow action combine to provide quiet refill operation. Since the ballcock assembly refill openings are above reservoir tank water level, water normally cannot be sucked through them and into the water supply system.

Abstract: An inlet valve mechanism for a toilet tank comprising a housing, a tapered valve seat and a tapered valve body. The valve seat and valve body are engagable with each other by the valve body moving reciprocally relative to the valve seat as the toilet tank is filled and emptied. The valve seat and valve body are made of a ceramic material.

Abstract: A ballcock is constructed with upper and lower housing members which are joined by a bayonet-type fitting. The juncture of the upper and lower members defines a valve chamber which sits atop the orifice of a vertical inflow tube carrying water from below the lower housing member. A valve in the valve chamber controls the flow of water out of the orifice. The valve includes separate, spaced upper and lower resilient valving members that provide a pressure chamber. Pressure in the chamber is controlled by a spherical-head metering pin passing through apertures in the upper and lower members. A slip-on silencer telescopes over the orifice and defines, with the exterior of the inflow tube, a quieting passage. The quieting passage has an annular intake at the top and terminates below in a pair of downward directed nozzles. The spherical-head metering pin makes a ball-and-socket connection with a lever. The lever is resiliently connected to the upper housing member and operated by a metal rod connected to a float.

Abstract: A differential pressure-actuated valve with a piston slidable to open or to close an inlet port. The piston slides in a cylindrical wall, and separates a bias chamber and a flow chamber. The piston is fitted with two oppositely-directed lip seals, one of which seals against bias chamber pressure, and the other of which scrapes particulate matter off of the wall. Optionally, an elongated filter extends from the piston into an inlet pipe where it filters water which flows to the bias chamber. The filter may have a perforated mesh wall, or a solid wall with an open end.

Abstract: A ballcock assembly having an upright standpipe for delivery of flush water, a control valve assembly at the upper end of the standpipe, and a float and ballast assembly slidably mounted for up and down movement relative to the standpipe and connected to the control valve assembly. The control valve assembly operates to open the valve to flow of flush water from the standpipe assembly in response to downward movement of the float and ballast assembly. When the float assembly is caused to rise by incoming flush water from the standpipe, it ultimately causes the control valve to shut off incoming flow of flush water from the standpipe.

Abstract: A valve assembly is adapted to control the water level within a toilet flush tank, by gravitational bodily movement of a hush tube and a valve housing integral therewith, responsive to emptying of the tank. A float coaxial with and secured fixedly to the hush tube is weighted in a manner to cause the gravitational motion of the hush tube and valve housing, when the float loses buoyancy as a consequence of the emptying of the flush tank contents. The gravitational movement of the float, hush tube, and valve housing in respect to an upstanding fill tube upon which these elements of the assembly are mounted for up and down sliding motion, causes actuation of a pilot reed valve. The pilot valve acts to break a valve seal between the fill tube and the valve housing, to an extent such that a very small force used in the opening of the pilot valve is sufficient to allow the normal line pressure to assert itself for full unseating of the valve and a consequent normal refilling of the flush tank.

Abstract: A valving system capable of maintaining a substantial flow rate to a low profile toilet bowl during bowl wash, bowl flush and refill, and storage tank refill. The system includes a tank refill tube and a bowl wash tube, with an adjustable restriction in one of them to balance the flow between them. When the toilet is flushed, water from the storage tank is emptied into the toilet bowl, causing the bowl contents to start to siphon out. A level-responsive valve opens when the tank level lowers, and supplies water both to the tank to refill it, and to the rim. It flows from the rim to wash the walls, to continue the flush, and to refill the bowl. A flow control can usefully be placed upstream from the valve so that a substantially constant flow rate results which is able to be accurately divided between the tank and the bowl, so that all functions are completed by the time the tank is refilled.

Abstract: An adjustable riser for a toilet tank is formed of a pair of mutually telescoped members slidably sealed to each other and readily locked in any one of a selected number of longitudinally adjusted positions by means of a number of tapered fingers having projections that are pressed into one of a series of grooves in the inner member by a threaded lock nut.

Abstract: An apparatus for isolating a ball-cock assembly locatable within a water closet flush tank from fluids contained within the flush tank has independent sleeve means of a material impervious to the fluid within the flush tank which is associated with a fluid riser of the ball-cock assembly and encloses the riser to provide a fluid-tight barrier between the riser and the fluid within the flush tank and mounting means for securing the sleeve means to the flush tank and providing a fluid-tight seal therebetween.

Abstract: An extendible ballcock assembly including a support pipe threaded at its lower end for partial receipt in a support fitting.The support fitting furthermore includes a peripheral cavity in the upper end thereof adapted to receive a toroidal seal.

Abstract: Telescoped inlet and outlet tubes having a valve between upper extremities thereof are each formed with end telescoped, upper and lower parts, the tube upper parts being assembled movable together and the tube lower parts being assembled movable together for simultaneously increasing and decreasing the respective tube end telescoping to selectively change the overall height of the ball cock. Positive securement in a height adjusted position against straight vertical relative movement is obtained by positive radial interengagement between the outlet tube parts with either selective relative rotation or selective release of the interengagement with re-engagement providing the height adjustment. An upper main case covers the valve assembly and an inner end of a float connected valve actuating lever projects into the upper main case to a case slot, being pivoted therein and operably connected to the valve.

Abstract: A valve for controlling the level of water in a toilet flush tank includes a body and cover having interfacing surfaces defining a valve chamber and a diaphragm chamber. A valve seat in the valve chamber communicates with a water inlet by way of a projection integral with the body adapted to extend through the flush tank water inlet opening to mount the housing in a normally submerged position. A diaphragm is held in the diaphragm chamber between the cover and body, and a flexible valve member is held in the valve chamber between the cover and body. An air passage defined in part by the projection vents the diaphragm chamber to atmosphere through the flush tank floor, and liquid pressure is communicated through the cover to the opposite side of the diaphragm. The water inlet passage extends to the center of the valve seat, which is surrounded by a valving surface having a number of segment shaped outlet ports communicating with water outlet passages in the valve body.

Abstract: A diaphragm controlled toilet bowl valve of simple construction that is substantially silent in operation, will not permit water to be siphoned from the tank in which it is disposed during an emergency in which the pressure of water in the supply lines decreases substantially, and one in which the actuating float is easily adjusted without hindering or deforming the rod on which it is supported.
