Abstract

PURPOSE:To permit suspension of operation of a vane in the held state and permit start from the non-compressed state by intercepting the conduction of a coil of a power source for controlling the movement of a movable iron core, when the supply voltage is lower than a standard voltage. CONSTITUTION:When an electric outlet is pulled-out during the operation of a rotary compressor 27A, the supply voltage of a compressor motor 42 is detected by a voltmeter 31, and the voltage monitoring part 32 of a microcomputer 43 judges whether the supply voltage is lower or not than a standard voltage set beforehand, and if the detected voltage is lower than the set standard voltage, a signal 44 for cutting-off the current to a coil 37 for holding the vane 2 through which said holding operation can be released from a power source 16 is transmitted to the power source which controls the movement of a movable iron core 38 for holding the vane 2 by inserting a pin 33. As a result of this, the movable iron core 38 immediately acts to hold the vane 2 and continues the above operation during the time in which a compressor motor 42 is in revolution, and the compressor 27A is stopped in the state of holding the vane 2. Start from the non-compressed state is permitted, and the starting torque can be reduced.
