    Abstract: A variable fluid displacement apparatus includes a plate which is located in a crank chamber and is tiltably connected to a drive shaft so as to vary the variable slant angle responsive to a pressure differential between the crank chamber and a suction chamber. A first communication path communicates the crank chamber with a discharge chamber to control pressure within the crank chamber. A first valve device opens and closes a first opening area in the first communication path to adjust the pressure level. A second valve device closes a second communication path, which communicates the crank chamber with the suction chamber. A second opening area in the second communication path is closed when a pressure difference between the crank chamber and the suction chamber falls below a predetermined value. Thus, a variable displacement compressor obtains a desired compression capacity after the variable displacement compressor commences operation.

    Abstract: A variable displacement compressor controls a discharge displacement by changing an inclination of a swash plate (5) depending on a pressure differential between a crank chamber (3) and a suction chamber (13) thereby to change a piston stroke. A first communication passage (18) establishes communication between a discharge chamber (14) and the crank chamber. A pressure control valve (19) opens and closes the first communication passage. On the other hand, a second communication passage (20) establishes communication between the crank chamber and the suction chamber. A valve member (21) is disposed in the second communication passage and fully closes the second communication passage due to a biasing force of a spring when a pressure differential between the discharge chamber and the suction chamber becomes not greater than a given value.

    Abstract: A slant plate type compressor with a capacity or displacement adjusting mechanism is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a member having a surface with an adjustable incline angle. The incline angle is controlled by the relative pressure between the crank and suction chambers. The relative pressure is controlled by a control mechanism which comprises a passageway communicating between the crank chamber and a suction chamber, a first valve device to control the closing and opening of the passageway and a second valve device to control the pressure in an actuating chamber. The first valve device includes a bellows and a valve shifting element coupled to the bellows. The valve shifting element includes a first surface which receives pressure in the actuating chamber and a second surface which receives discharge pressure in order to apply a force to the bellows at another and thereby shift the response pressure of the bellows in response to changes in the actuating chamber pressure and changes in the discharge pressure.

    Abstract: 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 immediately 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 visibility 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.
