AbstractA lubricating system for a scroll type compressor which includes a housing having a front end plate and a cup-shaped casing. A fluid inlet port is formed on the cup-shaped casing positioned opposite and opening onto a rotation preventing/thrust bearing device. In one embodiment, a cut portion may be formed in the fixed ring of the rotation preventing/thrust bearing device opposite the fluid inlet port. An oil passageway may then be formed in the front end plate to communicate between the cut portion and a shaft seal cavity.
