摘要： A toilet includes a bowl portion, a rim portion, and a reservoir. The bowl portion defines a bowl cavity that is in fluid connection with a trapway. The bowl cavity is configured to hold a volume of water to provide a water seal for the trapway. The rim portion extends about an upper portion of the bowl portion. The rim portion defines an internal rim cavity that extends about an upper portion of the rim portion and a plurality of apertures that extend from the internal rim cavity and through a sidewall of the rim portion to direct water from the internal rim cavity to the bowl cavity. The reservoir is in fluid communication with the internal rim cavity and the bowl cavity and configured to receive a supply of pressurized water from a water source and direct at least a portion of the pressurized water to the internal rim cavity.

摘要： The smaller volumes of water currently required to flush toilets and urinals may be insufficient to clear the fixtures and the drainage lines to which they are connected of waste and other undesirable materials, which can build up over a period of flushes or non-use. A flush valve control device programmed or otherwise configured to provide a selectable, periodic heavier flush volume of water after a predetermined number of low volume flushes and/or after a predetermined period of inactivity of the toilet or urinal can provide for sufficient drainage line carry-out of waste and prevent undesirable buildup of minerals, etc. on the inside surfaces of the fixtures and drainage pipes.

摘要： A flushometer toilet is used in a bathroom that has access to only a small diameter water supply pipe that usually would be useful only with a gravity toilet. A water storage apparatus (60) is provided that includes large diameter pipes (of 1.5 inches diameter) lying close to the flushometer valve (44) so at the beginning of a flushing, a large volume of water is available at a pressure of at least 30 psi.

摘要： A flush valve includes a body having a water inlet and a water outlet. There is an inner cover mounted on the body and with portions of the flush valve defines a chamber which is in communication with the flush valve inlet. A sensor for detecting the presence of an object adjacent the flush valve is mounted on the inner cover, as is an electrical circuit for causing operation of the flush valve. There is an outer cover which encloses the inner cover, sensor, and electrical circuit. The outer cover is formed of a plastic which will transmit radiation from the sensor whereby the sensor can detect the presence of an object adjacent the flush valve. The inner and outer cover have interfitting lugs which restrict relative rotation therebetween and provide a means for attaching the covers to the flush valve body through the use of a ring which applies a load only to the inner cover.

摘要： A bottom discharge toilet in which a trap is formed integrally with the toilet base. While the trap plays no role in the flushing action of the toilet itself, it is adapted to receive the discharge from other plumbing fixtures and thereby to serve as a single, common trap for such fixtures. By directing the received discharge through the interior of the toilet, the trap also assists in keeping the toilet outlet line clear. To further reduce the overall cost, the toilet is formed in several interlocking pieces as a kit which can be conveniently shipped and handled, and then assembled on-site. A novel water inlet valve operates in cooperation with a flushing mechanism to clear the toilet and refill the bowl with a minimum of water consumption.

摘要： A valve, plug and pressure responsive diaphragm combination for use in a flushing device of the type which includes a closed container for receiving and retaining a quantity of pressurized water. The plug is capable of being seated within the outlet of the tank and has an aperture therein into which the valve is slidably received. The valve is attached to a stem which in turn is affixed to the diaphragm. The valve is pushed downward from a seated position in the plug against the action of the diaphragm when the tank is flushed. This downward movement of the valve opens the aperture in the plug in which the valve was seated which decreases the pressure within the cylinder above the plug and causes the plug to move upwardly from its seated position in the tank outlet thus opening the outlet for the passage of water from the tank during the flushing cycle. As the tank empties, the plug, diaphragm and valve drop. The plug cannot move to a position lower than the seated position. However, when pressure in the tank is low, the valve can move in a downward direction from the seated position. Because the valve is free to move in a downward direction when the plug is seated, liquid can flow through the aperture in the plug to reseal a bowl after the tank has been flushed and the plug has been seated. To reseal the tank, the diaphragm responds to the pressure created by liquid coming into the tank, after the tank has been flushed, by rising and thereby slowly raises the valve until the valve is seated in the aperture in the plug.
摘要翻译：一种用于冲洗装置的阀，塞和压力响应隔膜组合件，其包括用于接收和保持一定数量的加压水的封闭容器。插头能够位于容器的出口内并且具有孔，可滑动地容纳阀。阀被连接到杆上，杆又固定在隔膜上。当罐被冲洗时，阀门从插座的就座位置向下推动，抵抗隔膜的作用。阀的这种向下运动打开阀座中的孔，其中阀被安置，其减小了塞子内部的气缸内的压力，并使塞子从其在罐出口处的就位位置向上移动，从而打开通道的出口在冲洗循环期间来自罐的水。当坦克清空时，塞子，隔膜和阀门掉落。插头不能移动到低于就座位置的位置。然而，当罐内的压力低时，阀门可以从就座位置向下移动。因为当插头就位时，阀可以沿向下的方向自由移动，所以当罐被冲洗并且插头已经就座后，液体可以流过插头中的孔，以重新密封一个碗。为了重新密封油箱，隔膜响应液体进入油箱后产生的压力，在油箱冲洗后，通过升高，从而缓慢升高阀门直到阀门位于插头孔中。

摘要： An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

摘要： A water delivery system includes a water input port, a control circuit, and a valve device. The water input port is constructed to be coupled to a water conduit receiving water from a remotely located water source. The valve device includes an actuator located near and connected to the water input port; wherein the valve device is constructed to receive control signals from the controller for providing water to a water delivery unit. The controller may be battery operated. The actuator may be a latching actuator, a non-latching actuator, or an isolated latching actuator. The controller may include a microcontroller coupled and to a sensor. The system may include a communication interface constructed and arranged to provide data to the microcontroller. The control circuit may include a power consumption controller. The control circuit includes a voltage regulator.
