A driving shaft is disposed within a compressor driving chamber. A swash plate is inclinably and slidably coupled to the driving shaft. The swash plate rotates together with the driving shaft at an inclination angle with respect to a plane perpendicular to the rotational axis of the driving shaft. A cylinder bore is disposed adjacent to the compressor driving chamber. A piston is disposed within the cylinder bore and an end portion of the piston is connected to a peripheral edge of the swash plate by a shoe. Preferably, the piston reciprocates within the cylinder bore to compress the refrigerant in response to rotation of the inclined swash plate. A rotor is connected to the driving shaft. A hinge mechanism connects the swash plate with the rotor and transmits torque from the driving shaft to the swash plate regardless of the inclination angle of the swash plate. The hinge mechanism includes a projection disposed on one of the rotor or the swash plate and at least one arm disposed on the other of the rotor or the swash plate. The projection has a recessed structure and at least one arm is coupled to the projection to transmit torque from the driving shaft.

摘要： A displacement control apparatus is used for a variable displacement compressor. The compressor is driven by an internal combustion engine. The compressor has an inclining swash plate and a piston, which is reciprocated by the swash plate. The stroke of the piston is changed in accordance with the inclination angle of the swash plate. The displacement of the compressor is changed between a minimum displacement and a maximum displacement in accordance with the stroke of the piston. The apparatus includes an actuator coupled to the swash plate. The actuator is actuated by exhaust pressure or intake pressure from the engine. A controller changes the inclination angle of the swash plate by actuating the actuator.

摘要： A vehicle air conditioning apparatus includes a refrigerant circulation circuit. The vehicle air conditioning apparatus has a variable displacement type compressor, a first pressure monitoring point, a second pressure monitoring point and an oil separator in the refrigerant circulation circuit. Also, the vehicle air conditioning apparatus has a control valve in the compressor. The compressor compresses refrigerant gas. Displacement of the compressor is variable. The refrigerant gas includes oil. The second pressure monitoring point is located more downstream than the first pressure monitoring point. The control valve controls the displacement based on differential pressure between the first and second pressure monitoring points. The oil separator is located between the first and second pressure monitoring points in order to separate the oil from the compressed refrigerant gas, thereby the oil separator serves as means for manifesting the differential pressure.

摘要： A variable displacement compressor has a housing, a drive shaft, a rotor, a swash plate, a piston and a decelerating mechanism. The housing includes a cylinder bore and supports the drive shaft. The rotor is secured to the drive shaft. The swash plate is operatively connected to the rotor and the drive shaft so as to rotate therewith and varies its inclination angle relative to the drive shaft. The piston is connected to the swash plate so as to reciprocate in the cylinder bore with rotation of the swash plate. A stroke of the piston varies in accordance with the inclination angle of the swash plate. The deceleration mechanism between the rotor and the swash plate decelerates the inclination speed of the swash plate in a range from a near maximum inclination angle to the maximum inclination angle when the swash plate inclines to increase the stroke of the piston.

摘要： A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.
