Claims

[Scope of utility model registration request]

It has a cylindrical piston inserted externally into the drive shaft and a cylinder into which the piston is inserted, and a wavy groove in the circumferential direction is provided on either the outer circumferential surface of the piston or the inner circumferential surface of the cylinder. In a compressor, a pin that fits into the wavy groove is protruded from the other side, and the piston is reciprocated in the axial direction by rotation of the drive shaft, and oil in an oil reservoir in the casing is guided to the pin. A compressor characterized by:
