    摘要： A mixing valve includes a housing having inlet ports and an outlet port that intersect at a valve chamber. A valve core within the valve chamber includes passages in fluid communication with the inlet and outlet ports. The passages intersect at a cavity within the valve core. An elastomeric seal retained within the cavity sealingly engages the valve core around the passages in the absence of fluid pressure in the inlets. Injection of a pressurized fluid in one of the inlets causes the seal to move away from both the corresponding inlet passage to permit fluid flow from the pressurized inlet port to the outlet port and compresses the seal around the other inlet port to provide a tighter seal than existed before application of pressure to the first port.

    摘要翻译： 混合阀包括具有入口和与阀室相交的出口的壳体。 阀室内的阀芯包括与入口和出口流体连通的通道。 通道在阀芯内的空腔处相交。 保持在腔内的弹性体密封件在入口处没有流体压力的情况下密封地接合通道周围的阀芯。 在一个入口中注入加压流体使得密封件从相应的入口通道移开，以允许流体从加压入口端口流到出口端口并且压缩围绕另一个入口端口的密封件以提供更紧密的密封件 在向第一港口施加压力之前存在。
