摘要： PROBLEM TO BE SOLVED: To prevent operational failure of a spool in a second control valve for adjusting opening of an extraction passage. SOLUTION: This variable displacement compressor reduces delivery capacity when crank pressure Pc increases, and increases the delivery capacity when the crank pressure Pc reduces. A first control valve CV1 adjusts opening of an air supply passage 29 for connecting a delivery chamber 22 and a crank chamber 5. The second control valve CV2 internally autonomously adjusts opening of a first extraction passage 27 for connecting the crank chamber 5 and a suction chamber 21, in response to valve opening of the first control valve CV1. The second control valve CV2 is composed of a spool valve, and a second valve part 88 is arranged in the spool 75. The second valve part 88 cuts off communication between a back pressure chamber 80 and a valve chest 71, via clearance 87 existing around a cylindrical surface 77 of the spool 75 in the second control valve CV2, when a first valve part 79 sets the first extraction passage 27 to minimum opening, in response to opening of the air supply passage 29 by the first control valve CV1.
