Kind Code:
Provided is a compressor in which an oil circulation ratio OCR is reduced with a simple structure. A cylinder head 104 has formed therein an intake chamber 141 towards the inside of the cylinder head in the radial direction and a discharge chamber 142 towards the outside, the intake chamber and the discharge chamber being separated from each other by a first ring-shaped partition 104d. In the center of the cylinder head 104, an oil retention chamber 148 is formed, the oil retention chamber being separated from the intake chamber 141 by a second ring-shaped partition 104e. A pressure release path 146 (101c → 101d → 103c → 148 → 104e1) communicates with a crank chamber 140 and with the intake chamber 141. Here, the oil retention chamber 148 constitutes a portion of the pressure release path 146, separates oil from a refrigerant flowing in the pressure release path 146, and retains the oil.
