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.
