PURPOSE:To provide the possibility of starting with a low voltage without requiring any particular start device, large-sized motor, or costly pressure control device by furnishing a solenoid to move a suction valve with a plunger which is in contact with the suction valve. CONSTITUTION:A plunge 19 in contact with the suction valve 14 is moved by a solenoid 20 installed on the outside of a cylinder head 16. When a compressor 1 is to be started, the plunger 19 in contact with the suction valve 14 is attracted by feeding current to the solenoid 20, and the load for fluid compression at this time is reduced by moving thereby the suction valve 14 and opening it forcedly, and also at the time with overload. the load of fluid compression due to high pressure is reduced. Thus it is possible to start a drive motor 2 with a low voltage, while at the time of overload, failure due to lock of the motor 2 is avoided. |
