<p>PROBLEM TO BE SOLVED: To ensure lubrication of a compressor at a high revolution of a vehicular engine. SOLUTION: The compressor 2 is driven by the vehicular engine 11, and has an electromagnetic capacity control valve 15 for controlling discharge capacity by a control signal received from external. The electromagnetic capacity control valve 15 lowers the discharge capacity by an increase in volume of discharged refrigerant flowing into a crank chamber of the compressor 2. A signal relating to speed of the vehicular engine 11 is inputted to a control apparatus 14 for controlling the electromagnetic capacity control valve 15. When the speed of the vehicular engine 11 is increased to a predetermined speed or more, the control apparatus 14 controls the electromagnetic capacity control valve 15 to lower the discharge capacity to be a predetermined value.</p> |
