Abstract: An improved water-saving toilet flapper valve (20) that calls for an end to automatic toilet flushing; instead it is operated manually. By manually depressing the toilet flush handle (72) for a desired amount of time, the user regulates the amount of water flushed down the toilet in a single session, thus saving water. A short flush interval or full flush interval can be achieved. This is accomplished by designing the flange body (50) of the toilet flapper valve to house a solid inner core (54) containing a weighted mass (56). This allows the toilet flapper valve to become non-buoyant when submerged underwater in a toilet tank (60). The flange body design is an improvement on prior-art since it acts as a flange to create a positive seal with the valve seat (68) of the toilet tank; thus preventing water leakage. This improved toilet flapper valve design can replace a standard toilet flapper valve without the need of additional tools or costly modifications.
Abstract: A toilet tank flush valve structure includes a valve base for installation in the outlet hole formed in the floor of a toilet tank and defining a water outflow passage and including a first valve member at the upper end of the water outflow passage. A float assembly is movable relative to the valve base between a sealing position in which a second valve member at a lower end of the float assembly engages the first valve member in sealing relationship and a flushing position in which the second valve member is spaced upwardly from the first valve member. The float assembly includes an outer shell that is open downwards and has a lower edge at which the shell is provided with the second valve member, and a closure member within the outer shell and cooperating with the outer shell to define a float chamber. The closure member is adjustable in position relative to the outer shell, whereby the float chamber is adjustable in volume.
Abstract: A cistern outlet valve assembly (10). The assembly includes an outlet orifice (14) and a buoyant member (20). The buoyant member (20) has an outlet seal (22) on one side and a housing seal (26) on the other. The assembly (10) also includes a valve housing (18) is adapted to cover the buoyant member (20). The housing (18) has large clearance guide means (30) adapted to guide movement of the buoyant member (20) from a closed position in which the outlet seal (22) seals against the outlet orifice (14) and an open position in which the housing seal (20) seals against the housing (18). When the buoyant member (20) is in the open position any fluid incident on the guide means (30) is prevented from flowing onto the buoyant member (20) by the housing seal (20) sealing against the housing (18).

Abstract: A tank valve for a lavatory has a body having a plug with a hollow. A flange is formed on a top edge of the plug. A pair of arms is formed on the flange and extends outwards. An upper ring made of a metal is mounted on a top surface of the flange. A lower ring made of a metal is mounted on a bottom surface of the flange. When a user releases a handle, the valve is immediately pivoted downwards to close a water outlet. Thus, a flow-out capacity of water can be controlled by a time of holding a handle, and a lot of water can be saved.
Abstract: Controlling a volume of water contained in the toilet's water tank by manipulating short or long a drawing line connected to an operating lever, includes an operating part having an operating member connected with the line and either operated short by pressing an auxiliary button along with the operating lever's handle, or operated long by pressing the overall handle without pushing the auxiliary button; a flush valve opening a drain pipe's intake with a buoyancy maintained if a working distance of the line is short; and a buoyancy control part letting the flush valve's upper part communicate with the water tank and closing the valve to remove the buoyancy if the working distance of the line is long. This system is easily installed in a drain pipe of the water tank already provided to the toilet body, and is capable of controlling a volume of water after installation just by turning the operating lever's handle in one direction only, thus attaining an advantageous economical aspect.
Abstract: A method and device for limiting upward movement of a flapper valve in a toilet having an overflow pipe, wherein upon flushing the toilet the flapper valve is raised to a maximum height. The device comprises a spherical body having a bore therethrough with a diameter slightly less than the diameter of the overflow pipe. The method comprises inserting the spherical body onto the overflow pipe and positioning it at a height on the overflow pipe such that upon flushing the toilet, the flapper valve is raised and contacts the spherical body, which prevents the flapper valve from being raised to its maximum height. The device limits the amount of water used with each flush and prevents the flapper valve from becoming stuck in an upright position.

Abstract: A reversible buoyant and non-buoyant flush tank valve is adapted for use in various types of flush tanks each having different selective valve operating attachments for moving the valve. The valve for use in one type of tank includes an elongated base with opposite end portions with a valve operating attachment selectivity at one end for opening and closing the valve. The other end portion of the valve is selectively attachable to the overflow pipe. The base has opposite sides with a vertically extending hollow frusto-conical cup member on one side. When the valve is used in another type of tank the opposite end portions are removed for connecting a vertical rod valve operating attachment to a first and second oppositely disposed bores to selectively position the cup member upwardly for non-buoyant operation or downwardly for buoyant operation.
Abstract: Savings in water consumption are obtained and problems with leakage are avoided by using a water-closet valve which is made of flexible air- and water-tight material and has not only a generally frustoconical seat-engaging portion provided with a pair of circumferential rings or protuberances so as to permit the formation of a double seal but also an interior hollow portion such that towards the end of a flushing operation there is produced within the valve member a partial vacuum which creates a thrust force to perfect the sealing of the valve member within its seat.
Abstract: An improved water closet valve is provided having two separate and distinct circular sealing rings interposed between the valve bulb and the conical opening which constitutes the valve seat. Both sealing rings may be secured to the bulb; both may be secured to the conical opening or one may be secured to the valve bulb and another to the surface of the conical opening. When the valve is in a closed position, at least two distinct spaced-apart seals are provided to obstruct the flow of water.
Abstract: This invention comprises an improved hydraulically operated flush valve for toilet flush tanks and similar devices. Its main components are a cylinder and piston assembly positioned with its longitudinal axis directly above and vertically aligned with the vertical axis of the outlet or flush tube of the flush tank. The moveable piston within the fixed cylinder acts as the moving and sealing element of the flush valve. By means of an inner valve connected to the flush tank operating lever hydraulic force is caused to lift the piston thereby opening the flush valve. There is no direct mechanical connection between the operating arm and the flush valve, and there are no chains or hinges. There is a positive permanent flush valve alignment and a minimum of friction. In addition, the amount of water used per flushing action can be regulated to prevent water and energy wastage.
Abstract: An improved ball valve for toilet flush tanks for regulating the quantity of water released from a tank in a flush includes a gauged or adjustable water inlet hole at the bottom of the ball valve and an air bleed hole at the top of the ball valve. The water inlet hole at the bottom of the ball valve is adjustable in size for selectively setting the flow rate of water entering the ball valve during a flush action, and thereby determining the time the ball valve remains open to allow flush water to drain from the tank.
