Abstract: A water saving device for a flush toilet comprising a flapper valve limit structure which yieldably limits the upward movement of a toilet tank flapper valve after it has been moved upwardly from its lower closed position towards its upper position thereby reducing the amount of water which will be discharged from the water tank into the toilet bowl during a flushing cycle.

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 flush and tap toilet water saver system is provided for use in the modem 1.6 gallon toilets that can utilize a flapper valve, a water supply valve which is controlled by a float ball, and a conventional operating handle. A main flapper valve has a bleeder valve installed thereon. The operating handle is rotated normally to open the main flapper valve and simultaneously open the bleeder valve thereby venting air from the main flapper valve and causing it to lose buoyancy and close sooner thus allowing only an abbreviated flush cycle in the toilet tank. When the operating handle is first pushed and then quickly tapped, the tap doses the bleeder valve and cuts off the venting air which causes the flapper valve to maintain full buoyancy and only close when the valve pusher mechanism rotates a valve pusher to force the flapper valve closed just when 1.6 gallons of water is released.

Abstract: A flush and tap flapper valve apparatus is provided for use in a toilet with a conventional operating handle. A main flapper valve has a bleeder valve installed therein. The flush handle is rotated normally to operate the main flapper valve and open the bleeder valve together thereby venting air from the main flapper valve so as to make the main flapper valve close faster causing an abbreviated flush cycle in the toilet tank. The flush handle when tapped just after the first push will close the bleeder valve and cut off the venting air and thus cause a full flush cycle.

Abstract: A water saver attachment for toilets being pivotally connected to selectively cover a drain pipe within a flush tank of the toilets. The water saver attachment includes a hollow L-shaped water weight box having a horizontal section with an open top side and a vertical section connected thereto. A support arm is connected to the hollow L-shaped water weight box and a cover is connected to the support arm. The water saver attachment is pivotally connected within the flush tank by a connection device. The water saver attachment is pivotable between a first at rest position in which the cover seals the drain pipe to prevent water from flowing therethrough and a second flushing position in which the water saver attachment is pivoted whereby the cover is pivoted to selectively allow water to flow through the drain pipe. The water saver attachment automatically pivots back to the first at rest position upon completion of flushing of the toilet to limit an amount of water flowing through the drain pipe.

Abstract: A dual flush valve that can be operated in a partial flush mode to release only about half of the tank water to the toilet bowl, or in a full flush mode to release almost all of the tank water, is of simple and reliable construction. For a partial flushing a chain device (64, FIG. 2) connected to the outer end of the flush member, is pulled to raise the flush member only a small amount (to 14C), and a release mechanism (90) is connected to a separate location on the flush member to keep it up until a float (110) senses that about half of the tank water has been released. The float pivots an arm (102) to disengage a latch 94 on the arm from a catch (96) on the yoke of the flush member to release it. The float slides along the refill/overflow tube (26).

Abstract: The Two-Level Flush Valve retrofits into standard toilet tanks replacing the flush valve and pull cord. Depressing the toilet handle through the usual first resistance lifts a non-buoyant valve (20) open. It is held open by an upper float (28) fastened onto a pull cord (24). When water lowers to the level of upper float (28) the float drops, allowing the valve to close. This accomplishes a short-duration flush that clears liquid waste from the toilet bowl and saves about a half tank of water. Depressing the handle through a second resistance causes valve (20) to pull a carriage (32) up and out of a latch (52). Lower floats (40) on carriage (32) hold valve (20) open until the tank is almost empty. This accomplishes a full flush that ensures that solid waste is flushed out without leaving dirty water in the toilet bowl. A valve delayer (62) holds valve (20) slightly open for a few seconds to allow complete refilling of the toilet bowl.

Abstract: A double flush toilet valve apparatus for permitting full and partial flushes of a toilet water tank by providing a vent hole in the toilet flush valve float which can be opened by an extended additional force actuation of the toilet flush handle to permit flooding of the float valve and premature closing of the discharge outlet of the toilet tank which is regulated by a float which is attached to the actuation chain of the toilet valve. The vent hole is regulated by a flapper seal and flapper seal actuator disposed within the flush valve float.

Abstract: A flapper valve for sealing the discharge outlet in a water tank and for regulating the quantity of water discharged during each flush by reducing the buoyancy of the flapper valve through water inflow into the flapper during flushing. The pivotally mounted flapper has an upper body section including an integral soft annular sealing flange and a downwardly depending body member. A cap is insertable at the lower ends of the side wall and defines a water inflow aperture therein. The cap is of a relatively rigid material and serves to support the buoyancy chamber formed by the upper body portion and the end cap against deformation under operating conditions. The cap may be provided with a valve disk for selective registry with one of multiple apertures to regulate the water inflow into the cone as a function of the dimension of the aperture selected in registry with the opening.

The connector is held in place by a radially outwardly extending flange and a locking ring inside the connector.

Abstract: A flush valve device is described for use in a toilet that includes a pressured water source, which can drain away water in the event of excess pressure with minimal modification to the toilet and which facilitates initial operation of the flush valve device. The flush valve device includes a valve member (16, FIG. 2 ) which lifts off a valve seat (22) at the beginning of a flushing, the valve member carrying a pressure operated relief valve (50) which dumps water at excess pressure through the opening (52) within the valve seat, to avoid the need for additional fluid-tight couplings in the water source. The valve member includes a sealing portion (60) which normally lies against the valve seat and which is lifted completely away from the valve seat during a flushing.

Abstract: A device for regulating the discharge of water from a storage tank associated with a toilet bowl for flushing of the toilet bowl, with the operation of the device being through slight pressure on a push button on a rod extending through a front or end wall of the storage tank. This device has a flapper assembly for opening and closing access to a drain from the storage tank, with this flapper assembly having a storage volume with an adjustable opening for controlled release of water therefrom to control the timing of the closure of the flapper assembly against the drain. A trigger assembly portion has a trigger arm with one end engaged with the push button and the other end adapted to engage a distal arm of a pivotal lever arm, this lever arm carrying a buoyant float. Release of the engagement of the distal ends of the trigger arm and the lever arm causes the lever arm to rise, due to the float, and the lever arm engages the flapper assembly to open the drain.

Abstract: A commode flush valve for providing short and adjustable flush cycles. The flush valve includes a valve seat around the upper end of a discharge pipe for a tank, and a body pivoted to it.

A cup beneath the valve seal has a perforation near its top for exit of air, and an opening at its bottom to enable water to flow therethrough. A removable insert is fitted in this opening with an orifice sized to regulate the rate of flow water therethrough, and perforations to enable substantially all water to drain from the cup where the valve seal rests on the valve seat.

Abstract: A semi-flush flapper valve apparatus is provided for use in a toilet and consists of a two position operable flush handle on the toilet tank. A main flapper valve has a bleeder valve pivotally mounted thereto. The operating handle is rotated in a first direction to operate the main flapper valve normally thereby causing a conventional full flush cycle in the toilet tank. The operating handle is rotated in a second direction to open the bleeder valve and operate the main flapper valve together thereby venting air from the main flapper valve so as to make the main flapper valve close faster causing a semi-flush cycle in the toilet tank.

Abstract: A double flush toilet valve apparatus and method for permitting full and partial flushes of a toilet water tank by providing a vent hole in the toilet flush valve float which can be opened by an extended additional force actuation of the toilet flush handle to permit flooding of the float valve and premature closing of the discharge outlet of the toilet tank which is regulated by a float which is attached to the actuation chain of the toilet valve.

Abstract: A valve assembly for selectively allowing either a partial or a complete draining of a toilet flush tank. A hollow valve member having both a small vent hole and a larger opening therein is selectively pivoted in a first or or a second direction depending upon which one of two activation levers is depressed. Opening the valve by pivoting it in one direction allows trapped air to vent from within the hollow valve. Inflowing water eventually imparts a negative buoyancy to the valve assembly and allows it to settle onto the valve seat to seal the tank prior to the discharge of the entire volume of water held by the flush tank. Alternatively, opening the valve by pivoting it in the opposite direction allows substantially less air to escape by virtue of the placement of the vent hole. The valve therefore never achieves negative buoyancy and the entire tank drains before the valve can settle onto its valve seat to seal the tank.

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: A flush valve for use in a flush tank for control by the operator of the amount used in flushing, the valve including an elongate body having a solid generally hemispherical protuberance extending outwardly on one side and a hollow frusto-conical cup member extending outwardly from the other side. A tab and opening therethrough on the forward portion of the body for connection to the valve operating system allows the valve to be alternatively turned with the cup member facing upward and being non-buoyant or having the cup member facing downwardly whereby air trapped therein renders the valve buoyant for substantially a full flush. Spaced arm members extend laterally from the rearward portion of the valve body and have one or more openings pivotally mounting the valve to the normal overflow tube to position the valve with respect to the water outlet in either selected position.

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.
