摘要： 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.

摘要： A scroll type compressor has both a high pressure lubricant sump and a low pressure lubricant sump. Lubricant from the low pressure lubricant sump is supplied to the various bearings, thrust surfaces and other moving components of the compressor. It is then rested in such a way that it can absorb heat from the motor windings thus maintaining the operating temperature of the motor. Lubricant from the high pressure sump is supplied to the moving compression chambers defined by the scrolls at a point intermediate suction and discharge. The lubricant supplied from the high pressure sump is first cooled and then used to cool the low pressure sump prior to being supplied to the moving compression chambers. The compressed gas is routed through two lubricant separators and a gas cooler prior to being supplied for its intended use.
