PURPOSE:To reduce vibration and noise during operation with a large capacity by electrically controlling a wobble type variable displacement type compressor so as to maintain the difference between blow-off and suction temperatures of an evaporator within a predetermined range. CONSTITUTION:Since a swing type swash plate 11 oscillates reciprocally through a rotary drive plate 8 by a rotary shaft 4 which is rotated, a piston 13 reciprocates in a cylinder bore 12. As a result, coolant gas is sucked from a suction chamber 3a into the cylinder bore 12 so as to be compressed, and thereafter, it is discharged into a discharge chamber 3. In this arrangement, computer C controls a solenoid control valve mechanism 15 in accordance with blow-off and suction temperatures respectively detected by temperature detectors 28, 34 and a temperature set by a temperature setting unit 31. Further, the pressure of a crank chamber 2a is electrically controlled so as to maintain the difference between the blow-off and suction temperatures within a predetermined temperature range. |
