    Abstract: A hybrid compressor selectively driven by an engine and an electric motor. The hybrid compressor includes a variable displacement compression mechanism. When the compression mechanism is driven by the motor, the cooling capacity of a refrigeration circuit that includes the hybrid compressor is adjusted by controlling the inclination of the swash plate and the motor speed. In the control procedure, the inclination angle of the swash plate and the motor speed are controlled so that the compression mechanism and the motor are most efficiently operated to achieve the required cooling capacity. Therefore, the hybrid compressor is constantly operated with maximum efficiency.

    Abstract: A control device is herein disclosed which comprises a drive piston 12p for changing the position of a slanting plate in a variable capacity pump 11, an electromagnetic proportional valve 13 for driving the drive piston, and a position detector 14 for detecting a position of the slanting plate. The control device performs a flow rate control of operating oil by controlling the electromagnetic proportional valve in accordance with a difference between a flow rate instruction value Fr for the operating oil and a position detection value from the position detector so as to change the position of the slanting plate. The control device further includes a pressure detector 18 for detecting a pressure of the operating oil supplied to an injection cylinder 10, and correcting means for correcting the flow rate instruction value on the basis of a pressure detection value from the pressure detector to output a corrected flow rate instruction value.
