Abstract
A compressor may include a shell, a bearing housing assembly located within and secured to the shell, a compression mechanism supported on the bearing housing assembly, a partition extending over the compression mechanism, and an annular seal assembly. The partition may be fixed to the shell and may abut an axial end surface of the bearing housing assembly to control a maximum axial distance between the partition and the compression mechanism. The annular seal may be sealingly engaged with the compression mechanism and the bearing housing assembly and may have a generally L-shaped cross-section including a first leg extending generally laterally between the compression mechanism and the partition. The first leg may have an axial thickness that is greater than the maximum axial distance.
