PROBLEM TO BE SOLVED: To provide a variable displacement compressor loading no unnecessary load to an engine in a high load area, and an air conditioning technology related to the compressor.;SOLUTION: A capacity control valve 30 constitutes a swash plate type variable displacement compressor 100, and is set so as to increase suction pressure Ps together with an increase in delivery pressure Pd in a low load area R3, and is set so as to reduce the suction pressure Ps together with an increase in the delivery pressure Pd. At this time, an inclination of a line L3(R3) and a line L1(R1) is different, and an inflection point T1 is formed between the low load area R3 and a medium load area R1. The valve is set so as to maintain the suction pressure Ps in a prescribed value regardless of an increase in the delivery pressure Pd in a high load area R2. At this time, the inclination of the line L1(R1) and a line L2(R2) is different, and an inflection point T2 is formed between the medium load area R1 and the high load area R2.;COPYRIGHT: (C)2003,JPO
