Claims

[Claims for Utility Model Registration] It is possible to slide along the outer periphery of one end of the drive shaft along the partial direction. A cylindrical piston is fitted into the drive shaft and has a communication hole between the drive shaft and the communication hole and a check valve at the top, and the piston is accommodated so as to be relatively slidable along the axial direction. , either the outer circumferential surface of the piston or the inner circumferential surface of the cylinder in a compressor comprising a cylinder having a valve plate having a valve hole and a check valve, and a casing housing the cylinder and having a gas suction port and a gas discharge port. A wavy groove having a predetermined period and amplitude meandering in a direction perpendicular to the axis of the drive shaft is provided on one of the cylinders, and a pin that slidably engages with the wavy groove is provided on the other side of the cylinder. The pin is fixed through a pin screw hole provided in the piston, and when the drive shaft rotates, the pin is held so as to slide in the axial direction, and when the piston slides in the suction direction, the suction port In the compressor configured to discharge the gas sucked in from the cylinder through the discharge port when the gas is slid in the compression direction, a lubricating oil filter is attached to the screw hole of the pin into the cylinder. A compressor characterized by:
