ABSTRACT:
A scroll-type compressor is provided in an inclined or inverted position with an oil sump disposed adjacent to a gas inlet of the scroll wraps to allow droplets of oil to be entrained in the gas being compressed so that the oil droplets in the gas can cool the scroll wraps. An oil injection fitting also extends through the compressor shell and communicates lubricating oil to a lubrication passage in the crankshaft for providing lubricant to the bearings of the crankshaft of the compressor and other components. The oil injection fitting is supplied with lubricant from an externally disposed source.
