    摘要： A solenoid plunger (36) is disposed for reciprocation in a plunger pocket that is formed by the stationary parts of a solenoid-type actuator (10). A flexible diaphragm (22) closes the plunger pocket's open mouth and is deformed by movement of a plunger (36) between an open position, in which it is displaced from a valve seat (20), and a closed position, in which it is seated on the valve seat and thereby prevents flow from a valve inlet (16) to a valve outlet (18). The diaphragm thereby isolates the plunger from the fluid thereby being controlled, but a separate, incompressible fluid fills the chamber in which the plunger reciprocates. A through-plunger passage (44, 56) provides a low-flow-resistance path for the incompressible fluid to flow into and out of the portion (52) of the plunger chamber behind the plunger as the plunger moves. This reduces actuation time and thus the energy required for an actuation. The chamber in which the plunger reciprocates is formed by elements (22, 26, 32, and 34) through which the incompressible fluid can diffuse only very slowly, so the actuator can be long-lived even if it small in size.

    摘要： A tank-type flusher including an intake valve, a diaphragm-operated flush valve, a pressure control mechanism. The intake valve is connected to an external water source and 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 that allows water discharge from the water tank into a toilet bowl. The diaphragm separates a pressure chamber and a pilot chamber. The diaphragm is arranged to seal the pressure chamber to maintain pressure forcing the flush valve member to the seated state thereby preventing the water discharge from the water storage tank to the toilet bowl. The pressure control mechanism is constructed an arranged, upon actuation, to reduce pressure in the pilot chamber of the diaphragm-operated flush valve thereby reduce pressure in the pressure chamber causing the water discharge. The tank-type flusher also includes a manifold that supplies pressurized water through a pressurizer conduit to the pressure chamber. A check valve maintains the pressure in the pressure chamber that keeps the flush valve closed, despite loss in source pressure.

    摘要： The present invention is directed to novel optical sensors and novel methods for sensing optical radiation. The novel optical sensors and the novel optical sensing methods are used, for example, for controlling the operation of automatic faucets and flushers. The novel sensors and flow controllers (including control electronics and valves) require only small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. A passive optical sensor includes a light detector sensitive to ambient (room) light for controlling the operation of automatic faucets or automatic bathroom flushers.

    摘要： An actuator base, bobbin, and pole piece form a pocket for an armature that a flexible membrane encloses to form an armature chamber filled with an incompressible fluid. The membrane protects the armature from exposure to corrosive fluids flowing in a conduit. Conduit flow can be stopped by driving the membrane against a valve seat. Pressure from the controlled fluid in the conduit is transmitted through the membrane to the fluid within the armature chamber so that the armature does not need to counteract force applied to the membrane by the conduit fluid's pressure.
