Abstract
An annular seal assembly which is adapted to be utilized in a vehicle air conditioning compressor. The seal assembly includes an outer annular support housing which is sealingly secured to the main body of the compressor in coaxial relationship with a rotatable shaft. An annular PTFE seal element includes an outer annular periphery sealingly secured to the support housing, and an inner annular periphery adapted to sealingly engage the rotatable shaft. In the preferred embodiment of the invention, the outer annular housing of the seal assembly is formed to include an inwardly facing annular recessed portion which is adapted to receive an annular gasket ring utilized to provide a seal between the PTFE seal element and the outer annular housing. The outer annular housing is also provided with an outwardly facing inner annular recessed portion which is adapted to receive a suitable tool for removing the seal element from the main body of the compressor.
