摘要:
A compressor includes a rotary shaft, a cam, a cylinder block, pistons, a thrust bearing, a rotary valve, and an oil passage. The rotary shaft has an in-shaft passage formed therein. The in-shaft passage has an outlet open to the outer peripheral surface of the rotary shaft. The cam rotates integrally with the rotary shaft. The pistons are coupled to the rotary shaft through the cam. The thrust bearing is provided between the cam and the cylinder block. The thrust bearing includes a first race in contact with the cam, a second race in contact with the cylinder block, and rolling elements retained between the first and second races to form a gap therebetween. The oil passage is formed in the outer peripheral surface of the rotary shaft so as to extend from the gap to the outlet of the in-shaft passage.
