压缩机密封组件
摘要：
一种压缩机，可以包括：罩体、第一涡旋构件、第二涡旋构件、以及密封组件。罩体限定第一压力区和第二压力区。第一涡旋构件可以包括限定室的第一端板。密封组件可以围绕排出通道并且将第一压力区与第二压力区彼此流体地分隔。密封组件可以包括第一密封构件和第二密封构件。当第二压力区内的第一流体压力比该室内的第二流体压力高时，第一密封构件可以防止该室与第二压力区之间的流通。当第一流体压力比第二流体压力低时，第一密封构件可以限定泄漏路径。当第一流体压力比第二流体压力低时，第二密封构件可以将该室与第二压力区流体地分隔。
摘要（英）：

A compressor may include a shell, first and second scroll members, and a seal assembly. The shell defines a first and second pressure regions. The first scroll member may include a first end plate defining a chamber. The seal assembly may surround the discharge passage and fluidly separate the first and second pressure regions from each other. The seal assembly may include first and second sealing members. The first sealing member may prevent communication between the chamber and the second pressure region when a first fluid pressure within the second pressure region is higher than a second fluid pressure within the chamber. The first sealing member may define a leakage path when the first fluid pressure is lower than the second fluid pressure. The second sealing member may fluidly separate the chamber and the second pressure region when the first fluid pressure is lower than the second fluid pressure.
