ABSTRACT:
A horizontal type rotary compressor includes a lubricant distribution system which does not require a check valve for preventing the return of lubricant from the frictional bearing surfaces to the blade chamber. An eccentric blade within a blade chamber pumps lubricant out of the blade chamber through an aperture in one wall thereof. A dispensing pipe communicates the aperture of the blade chamber with the frictional bearing surfaces and includes an opening in the pipe adjacent the blade chamber. Reciprocal movement of the blade causes lubricant to be sucked through the aperture of the blade chamber and discharged from the blade chamber into the dispensing pipe. The opening in the pipe permits a larger amount of lubricant to pass into the pipe than out of the pipe, thereby effectively acting as a check valve and negating the need for a separate check valve in the lubricant distribution system.
