Claims

[Scope of utility model registration request]

A cylinder head is attached to the upper part of the cylinder via a valve seat plate, and a suction chamber and a discharge chamber are defined inside the cylinder head, and the air inside the cylinder is connected to both chambers via a valve provided on the valve seat plate. In a reciprocating compressor in which a cylinder head is provided with a suction port communicating with a compression chamber and communicating with the suction chamber to the outside, and a discharge port communicating with the discharge chamber to the outside, at least one of the suction chamber and the discharge chamber. A plurality of inner fins are formed on the inner wall surface of the ceiling of the cylinder head facing the cylinder head in a direction substantially perpendicular to the air flow, and at least one of the plurality of inner fins is made longer than the remaining inner fins protruding from the inner wall surface of the ceiling. A reciprocating compressor characterized by:
