Abstract: The refill device is used with water-saving flush valves which retrofit into existing toilet tanks. These valves normally do not allow enough time to refill the bowl to its proper level. This diminishes their effectiveness and efficiency. The refill device is depicted here on a two-level valve of the inventor's previous patent. It comprises a chamber (40) between a valve (20) and a plate (34) which rotate up off of an outlet (22). As the valve is lifted the chamber contracts. After upper float (28) or lower floats (66) allow the valve to drop, water pulling down on the valve draws water into the chamber. The water pulls a flap (54) shut over a hole (56) in the plate. The plate then supports the chamber which holds the valve slightly open, permitting a predetermined amount of water to flow under it to refill the toilet bowl. Water seeps under the flap at a controlled rate allowing the valve to completely close.

Abstract: A flushing device which permits flushing with two different amounts of flushing fluid. The bottom valve member of the device comprises two float rods which are each connected to a float. The float rod for the small flushing amount is fixedly connected to the bottom valve member, whereas the float rod for the large flushing amount is connected to the bottom valve member via a lost-motion coupling to make it possible for the bottom valve member to move upwards and downwards relative to this float road. In the resting position, the float rod for flushing with the large amount of flushing fluid is locked by means of a lock, such that the float connected to this float rod does not affect the lowering of the bottom valve member towards its valve seat during flushing. The flushing with the small amount of flushing fluid will thus be determined completely by the movements of the other float rod and its associated float.

Abstract: The flushing device has an actuating device for optionally triggering a complete or partial flushing. A valve body of drain fittings is raised for this purpose. In the case of a partial flushing, the valve body is raised with a weight body, which loads the valve body with the valve body raised and brings same prematurely into the closed position against the lifting force of a float after a flushing process has been triggered. A coupling device has a switching member mounted on the weight body in its lower area. This switching member automatically connects the weight body to the valve body during the raising of the weight body with a pulling element connected to the weight body.

Thirdly, secure the second end of the line to a float floating in the toilet tank. Fourthly, use a plurality of direction altering line guides to orient the line such that when the flapper valve is in the open position and the water level falls, the lowering of the float exerts a force upon the line thereby pulling the float into the closed position.

Abstract: A two-stage flush device for a toilet tank comprising a cylindrical bolt adapted to be fixed in a hole of a side wall of a toilet tank and partly exposed out of the side wall, a rotatable button having a shaft portion fitting in a center hole of the cylindrical bolt and also firmly connected with a first actuating arm connected with a low-level valve by means of chain, a push rod having a push button at an outer side and extending through the center hole of the rotatable button to protrude through the center hole to operate a second actuating arm connected with a high-level valve by means of a chain, the first actuating arm lifted by the rotatable button for flushing a larger volume of water, and the second actuating arm lifted by the push rod for flushing a smaller volume of water.

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 bidirectional two-volume flush control mechanism which permits a part of the water to be suddenly driven out of the water tank when the trip handle is pulled upwards and, which permits the whole volume of the water to be completely driven out of the water tank when the trip handle is pushed downwards to move an actuating rod over a roller, which is mounted on the top end of a cylindrical float that is coupled to a swivel rod.

Abstract: An improved toilet tank flush control system provides a spring member which engages a rear surface of the flap control valve of the tank to apply a pressure to the flap tending to close it, which allows the user to control the amount of water discharged in the flushing action from a minimum up to the full quantity within the tank.

Abstract: An apparatus and a method for conserving the volume of water consumed during the flushing of waste deposited in the bowl of a toilet. A secondary water reservoir is mounted externally on the primary water reservoir of a conventional toilet. The primary water reservoir holds a first body of water whose volume is greater than a second body of water held by the secondary water reservoir. The first body of water may be discharged from the primary water reservoir directly into the bowl. Alternatively, the second body of water may be discharged from said second water reservoir into a water feed member which is mounted externally on the rim of the bowl and which directs said second body of water into said bowl along its perimeter in a slight downwardly direction.

Abstract: A device to restore the water level in a toilet bowl is disclosed wherein bleed water issued by the float actuated valve in a toilet tank reservoir is used to prime a syphon tube so that additional water from the toilet tank reservoir is shuttled down the overflow pipe to the toilet bowl to restore the toilet bowl water level during shortened partial flush operations of the toilet. The syphon tube consists of an inverted "U" shaped tube having one leg situated interiorly the overflow pipe and the other leg reaching down into the water of the toilet tank. The syphon tube operation is commenced by the bleed water injected into the base of the syphon tube through an initiator tube intersecting the syphon tube base so as to direct bleed water into the leg residing in the overflow pipe. An air vent opening situated in the initiator tube is effectively covered by water running through the initiator tube so no air is permitted to enter the syphon tube to disrupt the syphon operation.

Abstract: A flush device for toilet comprises within a water tank a support arm including a check member, a restricting member and a outlet valve attached in series to an overflow tube, and an actuating assembly including a actuator arm connected with the outlet valve via the support arm by a lift wire or chain.

Abstract: An improvement for a dual flush mechanism which permits a partial flush of a toilet in addition to the full flush. When the operator pushes the partial flush handle down, the partial flush mechanism lifts the flapper valve off the annular valve seat a small distance by raising the connected flush lever arm a similarly small distance. The improvement is a flush lever arm holder adapted to suspend the flush lever arm in the slightly raised partial flush position after the operator has released the partial flush handle. More particularly, a rotatable cam resides on a plate secured to the toilet tank wall, the cam, operably attached to a float, engages the underside of the flush lever arm such that the float holds the rotatable cam under the flush lever arm to secure it in the raised position during the partial flush. As the water level in the toilet tank falls, the float begins to fall with the water and lowers the cam holding up the flush lever arm.

Abstract: There is disclosed a level control valve arrangement preferably for use in a water closet cistern for controlling the liquid level in the cistern or container. The arrangement has a liquid inlet (3) feeding an inlet chamber (1) and a movable valve member (7,10) mounted on a seating (11,12) and movable between an open position in which liquid flows from the inlet into the cistern and a closed position in which liquid is prevented from flowing into the cistern. The movable valve member is biased preferably by a float arm into the closed position in response to liquid in the cistern rising to a predetermined level. 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.

Abstract: A flush control mechanism for a toilet and associated method that enables the toilet to be flushed with either a long flush cycle for solid wastes or a short flush cycle for liquid wastes. The present invention includes a nonbouyant flush valve that controls the duration of the flush cycle. A handle assembly is provided that is rotatably manipulative around its longitudinal axis from a set orientation to a rotated orientation. The handle assembly is also reciprocally manipulative along its longitudinal axis from an extended position to a retracted position.

Abstract: A system for controlling and saving water to be used with a toilet flushing apparatus permitting adjustable partial flush and full flush capabilities. A control housing having a pin inserted therethrough has a pointed tip portion entering an aperture formed in a bottom end of the control housing providing an adjustable needle valve. The effective size of the needle valve determines the rate at which water expels from the housing. A flexible tube attached to the control housing leads to a cavity in a flapper valve. The flapper valve covers a drainage port in a holding tank of a toilet when the toilet is unflushed. When the toilet is flushed, air is drawn from the cavity of the flapper into an inner chamber of the control housing as water leaves the control housing, thereby causing the flapper to change from a positive to a negative buoyancy state. The flapper can therefore be reseated upon the port before all the water has left the holding tank.

The lever restraining device being in a form of an angular restrainer has a ring connector attached to the overflow tube, a right-angled stop rod at a first side of the ring connector, and a positioning screw at a second side of the ring connector. This device controls the amount of the flush water discharged.

Abstract: There is disclosed a mechanism for initiating and controlling a toilet: flush mechanism of the type which permits selection between two flush cycles which use different volumes of water end which, to do that, requires that the flush valve be lifted to either of two levels. Each of two rotating handles drives a shaft which rotates a flush lever arm. The shafts are concentric. One of flush lever arms has a longer crank portion than the other so that points on the lever portion move a greater vertical distance for a given angular rotation than move corresponding points on the flush lever arm with the shorter crank portion. A single blocking member limits the rotation of both flush lever arms to the same range of angular motion. Tabs on a bushing for the shafts supplement the blocking member by stopping rotation of the handle approximately when the blocking member contacts the flush lever arm driven by that handle.
