PURPOSE:To obtain a control device for a variable capacity compressor having excellent control properties by providing an auxiliary control means supplementing the drive of a capacity varying mechanism for a compressor corresponding to a judging means judging the variation of control variables. CONSTITUTION:The capacity of a variable compressor 10 is controlled by a capacity control means depending on the thermal loading of refrigerating cycle. On the other hand, it is judged by a Judging means that the capacity of a variable compressor 10 is controlled by a control means, that is, the wobble plate 10d of a swash plate type compressor is driven. Then, the frequency of current driving a solenoid valve 10o is lowered corresponding to the aforesaid judgement so as to let the pressure in a crank room 10c be fluctuated for facilitating the movement of the wobble plate 10d. |
