ABSTRACT:
In a scroll type compressor unit including two interfitting fixed and orbiting scroll members in the compressor housing, a crank shaft projecting from the interior of the compressor housing and rotatably supported by a radial bearing, a crank pin on the inner end of the crank shaft on which the orbiting scroll member is rotatably supported by another radial bearing, and a rotation preventing mechanism for preventing the orbiting scroll member from rotating, an oil accumulating chamber is provided in the compressor housing to connect with the fluid inlet port of the compressor housing in order to lubricate those radial bearings and other moving parts. A shaft seal assembly is mounted on the crank shaft in a shaft seal cavity which is communicated with the oil accumulating chamber through a first oil passageway formed in the wall of the compressor housing. The compressor housing is provided with an oil deflector depending from its inner surface and a second oil passageway formed in the wall of the compressor housing to communicate between the interior of the compressor housing adjacent to the oil deflector and the oil accumulating chamber. The cool lubricating oil in the oil accumulating chamber circulates through the first oil passageway, shaft seal cavity, the interior of the compressor housing and the second oil passageway, lubricating the shaft seal assembly, the radial bearings, scroll members and other moving parts in the compressor housing.
