Abstract: An automotive air conditioner comprises a housing having an air flow passage defined therein. The housing includes mutually opposed side walls between which a part of the air flow passage is defined. A fan is installed in an upstream part of the air flow passage to introduce air into the air flow passage. An evaporator is installed in the air flow passage at a position downstream of the fan. The evaporator is of a stack type including a plurality of flat tube elements which are stacked on one another. Every adjacent two of the flat tube elements leave therebetween a clearance which has inlet and outlet sides. The evaporator is postured in such a manner that the flat tube elements extend between the mutually opposed side walls of the housing having the inlet sides of the clearances of the flat tube elements directed upstream toward the fan.

Abstract: In a variable displacement wobble plate type compressor, first, second and third connecting passages are defined. The first connecting passage fluidly connects a bellows chamber in which a bellows is installed with a suction chamber to which refrigerant from an evaporator is returned. The second connecting passage fluidly connects a discharge chamber and a crank chamber through a valve port. The discharge chamber is a chamber from which compressed refrigerant is discharged and the crank chamber is a chamber in which a wobble plate is operatively disposed. The bellows installed in the bellows chamber changes its volume in accordance with a pressure in the bellows chamber. A control valve controls the valve port in response to the volume change of the bellows. The third connecting passage is a passage which fluidly connects the suction passage and the crank chamber without using the bellows chamber as a part thereof.
