Claims

[Scope of utility model registration request]

It has a cylindrical piston attached to the drive shaft and a cylinder that accommodates the piston, and a groove meandering in a direction perpendicular to the axis of the drive shaft on either the outer peripheral surface of the piston or the inner peripheral surface of the cylinder. and the other side is provided with a pin that engages with the groove,
Reciprocating motion in which the piston and cylinder are held so that they can move relative to each other only in the axial direction due to the rotation of the drive shaft, and suction and discharge ports are provided that communicate with the cylinder chamber inside the cylinder, which is closed by the top surface of the piston. A reciprocating type compressor, characterized in that an upper cavity and a lower cavity communicating with a discharge chamber are provided at the upper part of the valve plate side end of the cylinder and the lower outer periphery thereof.
