Compressor

A compressor that includes a cylinder block that has a plurality of cylinder bores and has a piston mounted on each of the cylinder bores, and a cylinder head that is disposed on one end side of the cylinder block via a valve plate and defines a suction chamber on the inside thereof in a radial direction and a discharge chamber on the outside thereof in the radial direction, and in which the piston is reciprocated by a swash plate that rotates in synchronization with a driving shaft to draw a refrigerant into the cylinder bore from the suction chamber and compress the refrigerant within the cylinder bore to discharge the refrigerant to the discharge chamber, the compressor comprising:

• a pressure release passage that allows a crank chamber, in which the swash plate is disposed, and the suction chamber to communicate with each other;
• and
• an oil storage chamber that forms a portion of the pressure release passage and separates oil from the refrigerant flowing through the pressure release passage to store the oil,
• wherein the oil storage chamber is defined by an annular partition wall and the valve plate, wherein the annular partition wall is formed integrally with the cylinder head, is provided to protrude toward the valve plate from a bottom wall of the cylinder head, and has an outer peripheral portion surrounded by the suction chamber.
