Title:
圧縮機
Document Type and Number:
Japanese Patent JP6540954
Kind Code:
B2
Abstract:
An oil circulation ratio OCR of a compressor is reduced with a simple structure. A cylinder head 104 has a suction chamber 141 formed on the inside thereof in a radial direction and a discharge chamber 142 formed on the outside thereof in the radial direction, the suction and discharge chambers being separated by a first annular partition wall 104d. An oil storage chamber 148 is formed at a central portion of the cylinder head 104 by being separated from the suction chamber 141 by a second annular partition wall 104e. A pressure release passage 146 (101c→101d→103c→148→104e1) allows a crank chamber 140 and the suction chamber 141 to communicate with each other. The oil storage chamber 148 forms a portion of the pressure release passage 146, separates oil from a refrigerant flowing through the pressure release passage 146, and stores the oil.
