<P>PROBLEM TO BE SOLVED: To provide a displacement control system of a variable displacement compressor applied to the variable displacement compressor used together with a check valve, stably controlling delivery displacement in the vicinity of effective minimum delivery displacement by clearly regulating the effective minimum delivery displacement, and reducing consumption power in the variable displacement compressor. <P>SOLUTION: This displacement control system (B) of the variable displacement compressor includes the check valve (200), a displacement control valve (300) having a valve element (304) in which pressure of a suction pressure area and electromagnetic force of a solenoid unit of the variable displacement compressor (100) act in the direction for opposing pressure of a delivery pressure area of the variable displacement compressor (100), and electric current adjusting means (453, 454, 405) for adjusting an electric current supplied to a coil (316) of the solenoid unit based on external information detected by external information detecting means (403, 451, 452) and preset differential pressure of the check valve (200). <P>COPYRIGHT: (C)2010,JPO&INPIT |
