Abstract
A shaft seal assembly for a compressor in which the compressor includes a drive shaft adapted to be connected with the crank shaft of an combustion engine, comprising: an annular seal lip made of rubber and an annular seal ring made of fluoropolymer. The annular seal lip and seal ring are disposed in an axial direction which is substantially parallel with the axis of rotation of the drive shaft in such a manner that the escape of lubricating oil and refrigerant around the drive shaft is prevented.
