    Abstract: Sliding skirt valves for waterless urinals and method of controlling fluid flow through the sliding skirt valve are presented. The sliding skirt valve has a valve body, which includes an inlet, an outlet and a sealing surface. The sliding skirt valve also has a central shaft with an upper stop and a lower stop and a barrier interface. Between the upper and the lower stops, a conical barrier is slidingly engaged with the barrier interface. In a normal pressure state, the conical barrier lies against the lower stop of the central shaft. In a back pressure state, the conical barrier moves upwardly to lie against the upper stop of the central shaft and block the vent to upward fluid flow from the downstream of the sliding skirt valve.

  • Patent number: 8387652
    Abstract: An improved fill valve has a pivot valve body that is pivotally suspended immediately below a float housing and is movable between two positions. In a first position, the pivot valve body blocks the flow of water from the float housing. In a second position, the pivot body allows the flow of water from the float housing. The pivot valve body has two top compartments, each separated from the other by a wall. The first compartment retains an amount of water in it. The second compartment functions as a water flow restriction apparatus and includes an upwardly-extending member for sealing off a check valve that is disposed within the bottom of the float housing. The fill valve also includes a pressure compensating drip emitter that allows water to trickle into the float housing at a very slow rate.

Upon finding vacuum the deposit indicates that water was used for a normal bowl discharge or because the liquid leaked by the drain pipe because of anomalies in the discharge system, this valve will supply only what's necessary to fill the toilet bowl and tank to do a required flush, this valve won't supply water if the knob is not actuated to open the valve, or the lever to perform the same function.

The movable valve member (7,10) is mounted in the inlet chamber into which water is fed from the inlet (3) and in the closed position the valve is acted upon by a head of water in the inlet chamber to maintain the movable valve member in the closed position.

  • Patent number: 5408705
    Abstract: A toilet water reservoir inlet and outlet control valve utilizing a float and hydraulic activator. Both function simultaneously. Whenever the user flushes the toilet he will activate such valve, which will open to fill the reservoir with water, and the hydraulic activator will close the water inlet after a preset amount of time whether or not the reservoir is full of water. Such a valve will cut the water supply to the reservoir either by the float or by the hydraulic activator and such a valve includes a control to disable it partially in case of a bad part within it. Such a valve will enable the control the pressure to itself in order to prolong its life, and such a valve includes an adjustment that will control the cycle of closing such valve.

  • Patent number: 5287882
    Abstract: A toilet tank ball cock is designed for use in a toilet tank having an operating lever, a flush valve controlled by the operating lever and a water supply, with the ball cock regulating the supply of water to the tank. The ball cock includes a vertical riser column communicating with the water supply and a water control valve regulating the flow of water from the water supply to the toilet tank. There is a float movable on the riser column and coupled to the water control valve such that downward movement of the float to a selected level opens the water control valve to fill the toilet tank and upward movement of the float to a selected upper level closes the water control valve to stop filling the tank. The float has openings therein in communication with the tank interior. The openings are located to provide for water flow from the float as the water level in the tank drops.

  • Patent number: 5282280
    Abstract: A water conserving refill valve for a reservoir connected to a pressurized water supply. The valve includes a hollow body divided by a diaphragm into a first and second chamber and a hollow plunger extending through the diaphragm between the chambers. The first chamber communicates with the reservoir through a port and the second chamber selectively communicates with the reservoir through a relief valve. The plunger closes communication between the liquid supply and the first chamber while providing communication between the supply and the second chamber in a first position. In a second position, the plunger provides communication between the supply and the first chamber. The plunger is biased to the first position by a float lever. The reservoir includes a flush valve operated by a movable lever and the relief valve is connected to the movable lever to be opened when the flush valve is opened.

  • Patent number: 5179739
    Abstract: A toilet flushing apparatus designed to prevent excess loss of water that may happen when the flush valve stays open as the inlet valve is putting water into the tank. The initial flushing lifts the flush valve which acts in conjunction with a counter-weight and controller arm attached to the float ball arm. The controller arm supports the float ball and thus allows the intake valve to remain in the closed position until the flush valve has closed completely, at which time the float ball is lowered and water is let in to the tank.

  • Patent number: 5031250
    Abstract: The mechanism comprises an inlet valve assembly which admits water into a toilet tank under the control of a valve plug mounted on the end of a vertical axle having a float on its upper end. The valve plug is unseated, to admit water, when the axle is tilted, and the plug is pulled into seated position by the float when the tank is filled. A drainage buoy, in cooperation with a buoy base, allows discharge of water from the tank when the buoy is pulled from the base. Pull chains are used, from a toilet handle, to tilt the axle and pull the buoy. The inlet valve includes a water pressure reducer, and a non-return valve assembly to prevent return of water to the water supply in the event of a loss of water supply pressure.
