ABSTRACT:
A scroll-type compressor is disclosed which includes both a high pressure lubricant sump and a low pressure lubricant sump. Lubricant from the low pressure lubricant sump is supplied to the various bearing, thrust surfaces and other moving parts to lubricate same and a portion thereof is also supplied to the suction gas entering the compressor to replenish the lubricant in the high pressure sump. An oil separator is disposed in a discharge chamber to separate entrained oil from the compressed gas. A level control assembly is also provided in the discharge chamber and serves to return excessive accumulations of oil from the high pressure sump to the low pressure sump. In one embodiment, the compressor is specifically designed for compression of helium while in a second embodiment, the compressor is adapted for use as an air compressor.
