動することを特徴とする電磁クラッチ。[Claims for Utility Model Registration] A hold coil that is energized to connect the compressor and the power source during normal operation of the cooler cycle, and a hold coil that is energized and activated together with the hold coil to connect the compressor and the power source when the cooler cycle is started. However, in an electromagnetic clutch equipped with a start coil that is de-energized during normal operation, the start coil is connected to a pressure switch installed in the high pressure system of the cooler cycle, and the pressure switch maintains a constant value during normal operation. An electromagnetic clutch that is characterized by being activated when it detects and activates refrigerant pressure that exceeds that level.
