Abstract

CONTROL APPARATUS USED FOR A REFRIGERANT
CIRCUIT HAVING A COMPRESSOR WITH A VARIABLE
DISPLACEMENT MECHANISM
ABSTRACT OF THE DISCLOSURE
An automobile air conditioner system including a refrigerant circuit having a condenser, expansion element, evaporator and wobble plate type compressor with a variable displacement mechanism. Two passages communicate between the crank chamber and the suction chamber in the cylinder block. A bellows is disposed in a first passage and controls the communication between the crank chamber and the suction chamber response to crank chamber pressure. A control valve is disposed in the second passage and controls communication between the crank chamber and the suction chamber in the second passage in response to a signal representing the temperature of the air immedi-ately leaving from the evaporator. An electric clutch is mounted on the compressor in order to intermittently transmit the rotational motion of an automobile engine to the drive shaft of the compressor in response to the signal. The automobile air conditioning system is provided with a demist switch for preventing the reduction of visibil-ity through the windshield of the automobile. The operation of the control valve overrides the operation of the bellows without regard to the temperature signal when the demist switch is turned on.
