Document Type and Number:
Japanese Patent JP4246976
Kind Code:
B2
Abstract:
PURPOSE: To secure sealability at starting up of a compressor at a low cost. CONSTITUTION: A fixed scroll 6 and a movable scroll 7 are provided at the inside of a casing 3 provided with a suction port 3a and a discharge port 3b, and the movable scroll 7 is turned by a shaft 4. The shaft 4 is driven by a pulley 8 coaxially disposed at the shaft 4. An electromagnetic clutch mechanism 20 is provided between the pulley 8 and the shaft 4, and the electromagnetic clutch mechanism 20 is controlled by a control device 30. The control device 30 energizes a coil 21 of the electromagnetic clutch mechanism 20 when an engine temperature is lower than a first prescribed temperature T1 after a prescribed time passes after a driving instruction is performed to the electromagnetic clutch mechanism 20, thus obtaining the sealing capability around the shaft by heat generation of the coil 21.
