Abstract
A multi-piston swash plate type compressor, in which there is provided an improved internal arrangement for lubricating internal moving elements, especially steel ball bearings and shoes connecting the swash plate and the multi-pistons. The improved internal arrangement for lubricating the steel ball bearings and shoes comprises providing means for directly introducing a part of said oil particles suspended in the refrigerant gas which rushes into the combined block from the exterior of the compressor through one or more inlet ports formed in the combined block, into a swash plate chamber for rotatably mounting the swash plate therein, whereby the oil particles lubricate said ball bearings and shoes during operation of the compressor. The improved internal arrangement further contributes to effective employment of the blow-by refrigerant gas for distribution of oil lubricant to the cylinder bores along with said internal moving elements.
