AI Technical Summary

Problems solved by technology

During compressor operation, pressure fluctuations can displace seals, creating leak paths between areas of differing pressure
More severe pressure surges have the potential to deform or otherwise damage seals

Embodiment Construction

[0026] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0027] The present teachings are suitable for incorporation in many different types of scroll or rotary compressors, including hermetic machines, open drive machines, and non-hermetic machines. For purposes of illustration, compressor 10 is shown as a low side type hermetic scroll refrigeration compressor, i.e., as in figure 1 Shown in vertical section, where the motor and compressor are cooled by the suction gas in the hermetic housing.

[0028] see figure 1 with Figure 4 Compressor 10 may include seal housing assembly 12 , main bearing housing assembly 14 , motor assembly 16 , compression mechanism 18 , seal assembly 20 , refrigerant discharge fitting 22 , discharge valve assembly 24 , and suction inlet fitting 26 . Housing assembly 12 may house main bearing housing assembly 14 , motor assembly 16 , and compression mechanism 18 .

[0029] Housing assembly 12 may in...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Utility Patent Application No. 12 / 207,016 and US Provisional Patent Application No. 60 / 993,453, filed September 11, 2007. The entire disclosure of the above application is hereby incorporated by reference. technical field [0003] The present disclosure relates to compressors, and more particularly, to a seal for a compressor. Background technique [0004] This section provides background information which is not necessarily prior art related to the present disclosure. [0005] The compressor may include seals to isolate regions of different pressure from each other. During compressor operation, pressure fluctuations can displace seals, resulting in leak paths between areas of different pressure. More severe pressure surges have the potential to deform or otherwise damage the seal. Contents of the invention [0006] This section provides an overview of the disclosure, but is...
