摘要： A flush valve operating arrangement, having a pair of tubes between a flush valve actuator assembly and a remotely controlled unit for operating a flush valve; a third tube under supply line pressure is connected between the flush valve and the remotely controlled unit, which is responsive to supply line pressure from the third tube, and a control, coupled with the pair of tubes and with a fixture connected with the flush valve, responsive to water level in the fixture for prevention of actuation of the flush valve actuator assembly by the remote unit to thereby prevent overflow of the fixture and flooding of a surrounding area.A water level sensor is associated with the fixture, and includes a piston-housing assembly having an inlet and an outlet associated with the housing, a plunger associated with the water level sensor device either to isolate the inlet from the outlet or to place them into communication depending on the level of water in the fixture, and a bleed inlet line connected from one pair of the tubes to the inlet, and an outlet line connected from the water level sensor to a drain for diverting water in the one tube to the drain when the sensor activates the plunger to place the inlet and the outlet into communication and the remotely controlled unit is operated to place the pair of tubes into communication with the third tube.

摘要： A flush valve construction for water closets, urinals, showers and the like including a cylindrical jacket and associated piston assembly. A stop is adapted to be seated in the fluid supply line which will achieve flow adjustment and also render the valve inoperative and thereby permit repairs to the construction. The shaft supporting this stop is threaded and a nut is mounted thereon. This nut is positioned for engagement with the end of the valve piston to thereby control the stroke of the piston. This enables the saving of water by preventing an undue volume of water from passing through the valve during each operating cycle.

摘要： A cylindrical casing is attached at one end to a flush valve and at the other end supports an electric solenoid. Connecting fluid flow passages in the flush valve body and through the length of the casing lead to the solenoid valve seat. A piston in the casing is operated by hydraulic pressure through the fluid passages when the solenoid is operated. This action projects a plunger forward into the flush valve to cause it to operate. The solenoid may be operated by an electrical push button located at a remote point from the flush valve.

摘要： This control valve associated with flush valves in plumbing systems serves as a check valve which under certain conditions prevents the flush valve from operating unintentionally and causing flooding. The control valve has a loose valve plug which is spring pressed towards its seat and is arranged to shut off the water flow as well as throttle the flow through the flush valve. The control valve therefore serves three purposes; as a shutoff valve, as a check valve to prevent back flow, and as a throttle valve, all in a single unit.

摘要： The present invention provides a flush water tank device (4) that supplies flush water to an upper and lower spout port of a flush toilet (2) including; a flush water tank (10); a discharge valve (12); a first on-off valve (19) that performs switching between ejection and stopping of the flush water from the upper spout port; a first on-off valve driving mechanism (16) that is moved from a stopped position to an ejection position based on an user operation; a biasing mechanism (17) that causes the first on-off valve driving mechanism to move to the stopped position; a holding mechanism (20) that holds, at the ejection position, the first on-off valve driving mechanism at the ejection position against the bias force; and a releasing mechanism (21) that releases the holding of the first on-off valve driving mechanism, using the flush water flowing out from the first on-off valve.

摘要： A tank assembly for a pressure-assist toilet includes a flush assembly having an outer chamber and an inner chamber disposed in the outer chamber. The flush assembly further includes a flush valve disposed in the inner chamber, and a pilot valve disposed in the inner chamber and extending through the flush valve. The tank assembly further includes an actuator engaging the pilot valve and configured to hold the pilot valve at each of a first height, a second height offset a first distance from the first height, and a third height offset a second distance from the first height greater than a first distance.
