  • Patent number: 10934698
    Abstract: According to various embodiments, a toilet system includes a toilet fill valve and a bowl fill valve that is configured to attach directly to the toilet fill valve. The toilet fill valve can include a body having an extended portion that forms a bowl fill outlet port, a water inlet configured to couple to a water source, and a tank water outlet configured to output water to a toilet tank. The bowl fill valve can include a bowl fill valve inlet port that is configured to mate directly to the bowl fill outlet port of the body of the toilet fill valve, a bowl fill valve outlet port, a protrusion configured to insert into a recess of the toilet fill valve and retain the bowl fill valve to the toilet fill valve, a slot that is configured to receive an extension of the toilet fill valve, and a water flow adjustment handle.

  • Patent number: 9151028
    Abstract: A flushing valve suitable for reducing water wastage from a cistern of a toilet is described. The flushing valve comprising an inlet valve, an outlet valve and a timer valve. The timer valve is mechanically connected to both the inlet valve and the outlet valve so as to control their movement between an open and a closed position such that the timer valve prevents both the inlet valve and the outlet valve from simultaneously being in their open positions. By preventing the inlet valve and the outlet valve from simultaneously being in their open positions results in the fact that the flushing valve does not allow the cistern to start to refill until after the flush process is complete. This results in a significant reduction in the volume of water passing through the cistern during each flushing cycle.

  • Patent number: 6934976
    Abstract: A tank-type flusher includes an intake valve, i.e., a fill valve, a diaphragm-operated flush valve, and a pressure control mechanism. The intake valve is connected to an external water source and is constructed to close water flow to a water storage tank at about a predefined water level in the water tank. The diaphragm-operated flush valve is constructed to control a flush valve member between a seated state and an unseated state allowing water discharge from the water tank into a toilet bowl. There is a diaphragm, separating a flush-valve chamber and a pilot chamber, arranged to seal the flush-valve chamber and thereby maintain pressure forcing the flush valve member to the seated state preventing the water discharge from the water storage tank to the toilet bowl.

  • Patent number: 6321395
    Abstract: By depressing a push button (42), a toilet user opens a valve (44) that permits pressure holding a flush valve (12) seated to be exhausted through a pressure-relief line (48). The pressure in the flow path by which liquid thereby leaves the outlet (46) of the remote valve (44) tends to hold that remote valve's valve member (100) open after the user releases the push button (42). But pressure from the pressure-relief line (48) slowly builds up in a seating-pressure chamber (110) by fluid flow through a high-flow-resistance path provided by a passage containing a fluted pin (114). After a resultant delay sufficient to permit the toilet's tank (16) to empty through the outlet (22) controlled by the flush valve (12), the pressure within the seating-pressure chamber (80) reaches a point at which the force exerted by it on the valve member (110) exceeds the flow-path-pressure force tending to keep that valve member unseated.

  • Patent number: 5652970
    Abstract: A toilet reservoir water dumping valve for sealing the reservoir's water outlet by hydraulic pressure and for controlling the water volume to be flushed. The dumping valve is situated in the toilet reservoir at the water outlet to the toilet bowl, the dumping valve comprising a membrane housing, and a rod connected to a flush valve. In a first position, when the flush lever is in OFF position, the membrane disconnects communication between the supply line and the reservoir. Simultaneously, the rod is pressed by hydraulic pressure, tightly pushing a flush valve against the reservoir exit. In a second position, when the water is flushed, the membrane opens communication between the supply line and the reservoir, reducing the pressure on the rod, such that the rod pulls the flush valve away from the reservoir outlet, permitting water to be flushed down the toilet bowl.

  • Patent number: 5421038
    Abstract: A refilling preventing system for a toilet tank, to prevent refilling of the tank in case of a leak, comprising: a receptacle in the tank in which the buoyant float of the fill valve is placed; a water filling conduit to fill the receptacle after a flush discharge; a plug closing the overflow tube, to cause a momentary vacuum at a flush conduit of the toilet bowl connected to the discharge opening of the toilet tank after a flush discharge and when the stopper is at a closing position; and a siphon conduit, operable by a lever mechanism, which is connected to the discharge opening and to said receptacle, that allows to flush the receptacle, after a flush discharge, by a siphon effect created by the vacuum at the flush conduit of the bowl. In case of a leak emptying the tank, the receptacle will remain filled and the buoyant float will be at its closing position impeding the fill valve to refill of the tank.

  • Patent number: 4225986
    Abstract: A mechanism for releasing a selected volume of water from a tank has a U-shaped bracket which mounts on the interior of the tank via a bushing which passes through a hole in the wall of the tank. A rod is pivotally supported by the bushing and, in turn, supports a valve which mates with the tank drain when the rod is pivoted to raise a valve support arm to which the valve is attached. A key on a latch arm pivotally mounted on the bracket falls into a notch in the periphery of a latch collar on the rod when the rod is pivoted to raise the valve so that water is drained from the tank so long as the key is engaged by the notch. A float collar journally mounted on the rod is positioned by a float as the water level falls to move an electrical contacting member on the float collar along an arcuate path.
