<p>PURPOSE: To provide a variable delivery compressor which is excellent in housing performance and installing workability to an engine room. CONSTITUTION: A solenoid opening-closing valve 55 to adjust pressure of a crank chamber 25 is arranged in the middle of a pressure supply passage 54 so as to be adjacent to a delivery muffler 41 above a compressor main body. In the pressure supply passage 54, its one end is opened in a lower end part of a delivery chamber 40, and the other end is opened in the crank chamber 25, and a delivery pressure area and the crank chamber 25 are connected to each other. In compressing operation in minimum delivery capacity, refrigerant gas is sent to the crank chamber 25 from the delivery chamber 40, and is also sent to a suction chamber 38, and the inside of a compressor is lubricated. The solenoid opening-closing valve 55 opens and closes the pressure supply passage 54.</p> |
