Abstract: A compressor may include a shell, a compression mechanism, and a seal assembly. The shell may define a first discharge passage. The compression mechanism may be supported within the shell and may include first and second scroll members. The first scroll member may include a second discharge passage. The seal assembly may extend between the first scroll member and the shell and may form a sealed discharge path between the first and second discharge passages. The seal assembly may include a first seal member axially displaceable relative to the shell and the first scroll member. The first seal member may axially abut the first scroll member when in a first position and may be free from axial contact with the first scroll member when in a second position. The seal assembly may maintain the sealed discharge path when the first seal member is in the first position.

Abstract translation: 压缩机可以包括壳体，压缩机构和密封组件。 壳可以限定第一排放通道。 压缩机构可以被支撑在壳体内并且可以包括第一和第二涡旋构件。 第一涡旋构件可以包括第二排放通道。 密封组件可以在第一涡旋构件和壳体之间延伸并且可以在第一排出通道和第二排出通道之间形成密封的排出路径。 密封组件可包括相对于壳体和第一涡旋构件可轴向移位的第一密封构件。 当处于第一位置时，第一密封构件可以轴向地邻接第一涡旋构件，并且当处于第二位置时，第一密封构件可以不与第一涡旋构件轴向接触。 当第一密封构件处于第一位置时，密封组件可以保持密封的排出路径。
