To provide a control device for a hybrid compressor which prevents the efficiency deterioration of a refrigerating cycle during the drive of an electric motor.
A compressor body 101 of the hybrid compressor 100 is of a variable discharge displacement type decreasing discharge displacement by the pressure buildup of a crank chamber 15 and increasing discharge displacement by the pressure drop of the crank chamber 15. The pressure of the crank chamber 15 is regulated by changing the opening of a supply passage 38 that connects the crank chamber 15 to a discharge chamber 28. An air conditioner ECU 70 regulates the rotating speed of an electric motor part 102 and the valve opening of a control valve 39. At the stop of an engine E, the air conditioner ECU 70 controls the refrigerant discharge per unit time of the compressor body 101 by regulating the rotating speed of the electric motor part 102 in the state of the control valve 39 being fixed to total closure.
