A tank-type flusher is located in the water storage tank for flushing a toilet. The tank-type flusher includes an intake valve and a flush valve. The intake valve is connected to an external water source and constructed to close water flow to the water storage tank at about a predefined water level in the water tank. The flush valve is constructed to control a flush valve member between a seated state and an unseated state allowing water discharge from the water tank into a toilet bowl. The tank-type flusher may be controlled by a sensor module located at a reference location external to the water storage tank.

Toilet flusher for water tanks with novel valves and dispensers

A tank-type flusher includes an intake valve, i.e., a fill valve, a diaphragm-operated flush valve, and a pressure control mechanism. The intake valve is connected to an external water source and is constructed to close water flow to a water storage tank at about a predefined water level in the water tank. The diaphragm-operated flush valve is constructed to control a flush valve member between a seated state and an unseated state allowing water discharge from the water tank into a toilet bowl. There is a diaphragm, separating a flush-valve chamber and a pilot chamber, arranged to seal the flush-valve chamber and thereby maintain pressure forcing the flush valve member to the seated state preventing the water discharge from the water storage tank to the toilet bowl. The pressure control mechanism is constructed and arranged, upon actuation, to reduce pressure in the pilot chamber of the diaphragm-operated flush valve to cause deformation of the diaphragm and thereby reduce pressure in the flush-valve chamber causing the water discharge.

Toilet flusher with novel valves and controls

A valve device and a method for operating at least two valves is actuated by an actuator and arranged for controlling fluid flow in at least two separate fluid lines. The two valves are preferably diaphragm operated valves, but may be also piston valves. The valve device includes a pressure release mechanism constructed to change pressure in a diaphragm chamber of each diaphragm operated valve and thereby open or close the valve. The pressure release mechanism may include a fluid passage in communication with each diaphragm chamber, where it is simultaneously controlled by a movement of a single sealing member actuated by a single actuator. The valve device may also include a manual actuator.

Device and method for operating at least two valves

A combination junction provides a fluid, electrical-power and control-signal connections. A combination tap comprises a flow probe that pierces a main conduit when it is attached to it. It thereby provides fluid communication between a tap conduit and the main conduit. The combination tap also includes one or more tap electrical conductors to tap electrical conductors embedded in the main-conduit wall.

Method and apparatus for combined conduit/electrical-conductor junction installation

Disclosed is a valve device and a method for operating at least two valves actuated by an actuator and arranged for controlling fluid flow in at least two separate fluid lines. The valve device can simultaneously control at least two diaphragm operated valves using a single actuator. The valve device includes a pressure release mechanism constructed to change pressure in a diaphragm chamber of each diaphragm operated valve and thereby open or close the diaphragm operated valve.

Pressure from the input water line (,) holds a toilet's flush-valve member (,) in its seat so as to prevent water in the toilet tank (,) from flowing through flush ports (,) and a flush conduit (,) into the toilet bowl or urinal. To release water through the flush conduit (,) a solenoid (,) is actuated to relieve the pressure acting on the flush-valve (,) so that a bias spring (,) lifts the flush-valve (,) off its seat (,). A solenoid (,) for performing this function can be located remotely from the flush-valve assembly and communicate with it by a hydraulic line (,).
