摘要： A diaphragm valve cartridge for a faucet wherein a generally cylindrical valve body has a surface recess which receives at least one resilient valve member of rubber-type material of conforming size. An inlet port from a support duct and an outlet port to a discharge duct are located in the valve body recess in spaced relation with the recess walls and bottom engaged by the valve member. A retainer holds the valve member in the recess and applies sufficient pressure on the marginal portion of the valve member to establish a liquid-proof seal between the valve member and valve body which exists at least at low liquid pressure. The resilient valve member responds to liquid pressure within the valve, and the seal with the valve body is enhanced in proportion to liquid pressure, giving the valve a self-sealing characteristic over a wide range of liquid pressures. A movable actuator has a cam surface which positions the resilient valve member in relation to the inlet port, closing the port in one position, and in other positions varying the spacing between the valve member and port for varying the rate of flow through the valve. The various parts of the valve, including the actuator, are preassembled economically, and the valve is installed at the point of use as a unit, thereby avoiding any installation step, such as conventional compression seal, which might permit leakage in the valve. The disclosed valve has two supply lines, and when one of these is externally blocked, the valve operates as a single supply line valve. The liquid handled by the valve flows from the supply duct to the discharge duct without traversing a region within the valve cartridge from which leakage is possible as a result of abuse or improper installation. Valves embodying the invention easily can be installed by the user without tools of any kind, and the structure involved in installation is such that leakage at the couplings for the supply and discharge lines is virtually impossible.
摘要翻译：一种用于水龙头的隔膜阀芯，其中大致圆柱形的阀体具有接收至少一个符合尺寸的橡胶类材料的弹性阀构件的表面凹槽。从支撑管道和出口到排放管道的入口端口位于阀体凹部中，与凹部壁和由阀构件接合的底部间隔开。保持器将阀构件保持在凹部中并且对阀构件的边缘部分施加足够的压力，以在至少存在液体压力的阀构件和阀体之间建立防液体密封。弹性阀构件响应于阀内的液体压力，并且与阀体的密封度与液体压力成比例地增加，使阀在宽范围的液体压力下具有自密封特性。可移动致动器具有凸轮表面，其将弹性阀构件相对于入口端口定位，将端口关闭在一个位置，并且在其它位置改变阀构件和端口之间的间隔，以改变通过阀的流量。阀门的各个部件（包括致动器）经济地预先组装，并且阀门作为一个单元安装在使用点处，从而避免任何可能允许阀门泄漏的安装步骤，例如常规的压缩密封件。
