Patent ID: 7207784

Claim:
A control device in a hybrid compressor that is within a refrigerating circuit and driven by one of an engine and an electric motor, wherein the hybrid compressor includes a compression mechanism that is driven by rotation of a swash plate, and an inclination angle of the swash plate is varied by a capacity controller that is externally controlled, the control device comprising a controller for (i) operating the hybrid compressor, after the engine stops, in a low capacity state, in which a displacement of the hybrid compressor is decreased to a second displacement from a first displacement that is generated by the engine before the engine is stopped, (ii) then operating the hybrid compressor by setting the capacity controller to a first control value to trigger the swash plate to be rapidly inclined when the hybrid compressor starts being driven by the electric motor, and (iii) then operating the hybrid compressor by setting the capacity controller to a second control value after the controller has operated the hybrid compressor based on the first control value, wherein the first control value increases the displacement more than the second control value does, and the second control value is obtained from a status of the refrigerating circuit.
