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.

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 valve used in a variable displacement compressor includes a valve chamber, a valve body and a pressure sensing chamber. A pressure sensing ball is movably located in the pressure sensing chamber and divides the pressure sensing chamber into a first pressure chamber and a second pressure chamber. First and second pressure monitoring points are located in a refrigerant circuit. The first pressure chamber is exposed to the pressure at the first pressure monitoring point. The second pressure chamber is exposed to the pressure at the second pressure monitoring point. The ball is displaced based on the pressure difference between the first pressure chamber and the second pressure chamber. The position of the valve body is determined based on the position of the pressure sensing member.

摘要： The object of the present invention is to offer a structure of a suction valve enough to prevent a noise or clatter caused by vibrations of a suction valve in a variable displacement compressor having pistons. The suction valve is a bendable flexible valve composed of flexible portions, and of a closing portion placed adjoining to the flexible portions to form a free end to close a suction port. The lengths of the flexible portions of the suction valve are nearly equal, but the widths of the flexible portions of the suction valve are different each other. And the distance between the suction valve and a receiving portion which regulates maximum opening degree, is determined so that the lower bending flexibility side of the flexible portions contacts the receiving portion from the beginning or as soon as the suction valve starts to open, and that the higher bending flexibility side of the flexible portions approaches the receiving portion with the lower bending flexibility side of the flexible portion contacting the receiving portion, while the suction valve is twisted.

摘要： An improved control apparatus for a vehicle air conditioning system controls a variable displacement compressor. The discharge capacity of the compressor is changed by changing the difference between the pressure in the crank chamber and the suction pressure. The difference between the pressure in the crank chamber and the pressure of the suction chamber is maintained at a set value. A target value is determined based on the temperature of the passenger compartment. The target value is corrected based on the rotational speed of the engine driving the compressor, which is detected. The set value is determined by the corrected target value.

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 control valve used for a variable displacement compressor comprises a valve housing, a valve chamber defined in the valve housing, a valve body. The valve body is located in the valve chamber. A pressure sensing chamber is defined in the valve housing. A movable wall is located in the sensing chamber to divide a first pressure chamber and a second pressure chamber. The movable wall moves in accordance with the pressure difference between the first pressure chamber and the second pressure chamber. A rod transmits the movement of the movable wall to the valve body. The pressure directed in the vicinity of the end portion of the rod is the same type pressure directed in the first pressure chamber or in the second pressure chamber. An actuator determines the target pressure difference between the two pressure chambers. This permits the displacement of the compressor to be quickly changed.

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.
