ABSTRACT:
There is disclosed herein a lubrication system for a compressor which provides means for separating and flushing foreign particles contained in the lubricant so as to minimize the number of such particles being circulated through the lubrication system thereby reducing the possibility of damaging the bearings. The foreign particles are separated from the main lubricant flowpath by centrifugal forces and are flushed downwardly into collection means in the lower bearing housing and out through a passage provided therein back to the oil sump. An extension of this passage in the lower bearing housing is also adapted to cooperate with a portion of an axial thrust bearing to prevent rotation thereof.
