Abstract: A control unit for a clutchless variable displacement compressor with a solenoid is used in an air conditioning system for vehicles. The control unit includes a solenoid drive for adjusting a current flowing in the solenoid, a voltmeter for detecting a voltage applied to the solenoid, an ammeter for detecting the current of the solenoid, and a control for supplying current to the solenoid drive during a first predetermined time period when the air conditioning system is not in operation, and current has been prevented from flowing to the solenoid during a second predetermined time period. A resistance of a coil of the solenoid is calculated from the detected voltage and the detected current. A temperature of the compressor is determined from the calculated resistance based on a predetermined relationship between the resistance and the temperature of the coil of the solenoid when the air conditioning system is not in operation; the compressor is operated by supplying current to the solenoid when the calculated temperature exceeds a set value. Thus, the temperature of the compressor may be detected by a control mechanism, and the compressor may be protected against an excessive increase of temperature.

Abstract: A variable capacity type slant plate type compressor including a crank chamber, a suction chamber and a discharge chamber is disclosed. The crank chamber is linked by a first communication path to the suction chamber, and is linked by a second communication path to the discharge chamber. A first valve control mechanism is disposed within the first communication path and second valve control mechanism is disposed within the second communication path. Fluid communication between the crank and suction chambers is controlled by the first valve control mechanism so that the suction chamber pressure is maintained at one predetermined constant value while fluid communication between the crank and discharge chambers is continuously closed. Fluid communication between the crank and discharge chambers is opened by the second valve control mechanism when the predetermined constant value of the suction chamber pressure must be increased. However, in the latter condition, fluid communication between the crank and suction chambers is continuously closed as long as the crank chamber pressure is not abnormally increased.
