ABSTRACT:
A piston type compressor has a plurality of cylinder bores in which a plurality of pistons reciprocate to effect suction, compression and discharge of refrigerant gas in response to rotation of a drive shaft. The compressor has a gas receiving chamber for receiving the refrigerant gas before compression, a discharge chamber for receiving the compressed gas, and at least one rotary valve mounted on the drive shaft to be rotatable with the drive shaft. The rotary valve has a suction passageway for providing fluid communication between the gas receiving chamber and each of the compression chambers formed in the cylinder bores. A groove is provided on the outer circumferential wall of the rotary valve. The groove is connected with the outlet of the suction passageway and extends to a vicinity of the opposing end portions along the outer circumferential wall. The groove supplies the lubricant oil within the refrigerant gas in the suction passageway to and between the outer circumferential wall of the rotary valve and the inner wall of the recessed chamber during the rotation of the rotary valve.
