Abstract

A swash-plate type compressor wherein a valve plate confronting an oil reservoir is provided with a vertical oil passage therein which is communicated with the oil reservoir via a relatively large through-bore formed at the lower end thereof, and is also provided with a gas inducing bore of a small diameter at a slightly higher position than the oil level in the oil reservoir for communicating therewith. By means of advantageously utilizing the pressure difference between the inside of the oil reservoir and that of the suction chamber as well as the centrifugal force caused by the rotation of the driving shaft and the swash-plate, the oil in the reservoir can be carried up together with the blow-up gas to each of the places requiring appropriate lubrication through two of the passages for the mixture of gas and oil, tandem arranged, large diametered and then small diametered, bored through the driving shaft, and a plurality of oil distribution bores formed in the boss of the swash-plate.
