摘要： A electromagnetic control valve which is capable of controlling with small electromagnetic force is provided. In such electromagnetic control valve, a pressure-sensitivity control mechanism is provided in a space leading to the suction side of the compressor such that the pressure-sensitivity control mechanism faces to the crankcase pressure introducing opening of the valve main body. This pressure-sensitivity control mechanism is formed by a piston which comes into contact with the bottom surface of the valve rod. The differential pressure between the crankcase pressure and the suction pressure of the compressor is detected by the piston. Upon receipt of detection signals from a temperature sensor and a pressure sensor and an external signal, the pressure-sensitivity control mechanism adjusts the flow of refrigerant from the discharge side (high-pressure side) to the crankcase side of the compressor. Thus, the differential pressure can be controlled.

摘要： A control valve used in a variable displacement compressor. The valve includes a valve chamber having a valve hole. A valve body is accommodated in the valve chamber for selectively closing and opening the valve hole. An opening spring urges the valve body in a direction opening the valve hole. An actuator generates force in a direction closing the valve hole. A solenoid rod transmits the force of the actuator to the valve body. A pressure sensing chamber is defined independently from the valve chamber to receive refrigerant from a suction passage. A pressure sensing member is located in the sensing chamber for sensing the pressure in the sensing chamber. A pressure sensing rod transmits the pressure sensed by the sensing member to the valve body. A compression spring, a cap and stoppers maintain proper alignment of the pressure sensing member. The valve body is moved based on the refrigerant pressure sensed by the sensing member, the force of the spring and on the force of the actuator.

A bellows actuates the valve body through a first rod in accordance with an operating pressure introduced to a pressure sensing chamber. A solenoid biases the valve body through a second rod with a force based on the level or an electric current supplied to the solenoid. The cross-sectional area of the second rod is no smaller than the cross-sectional area of a valve hole of the control valve.

The cylinder block has a shutter chamber opening to the first end and the second end. A shutter member is accommodated in the shutter chamber. The shutter member is movable between a first position and a second position in response to the inclination of the drive plate to selectively connect and disconnect an external circuit with an suction chamber. The drive plate is held at the minimum inclination position when the shutter member is positioned in the second position. The shutter chamber has a diameter that is constant in an axial direction with respect to the shutter chamber. The shutter member is removably inserted into the shutter chamber from the second end of the cylinder block.

摘要： In a variable-capacity swash-plate type compressor, which can vary the outlet capacity by controlling an inclination angle of a swash plate, the swash plate is aligned by contacting a washer (19) with a tapered surface to the swash plate (18). Thus, in a case where a compression operation is not carried out or in a case where a compression operation is carried out at a small outlet capacity regarded as zero substantially, the noises, etc., which generate between the swash plate and a driving shaft (6), are inhibited.

摘要： A control valve is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve has a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber. The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber and the second pressure chamber forms a part of the refrigerant circuit.

摘要： The variable displacement swash plate compressor includes a housing, a drive shaft, a swash plate, a piston, a bleed passage, a supply passage and a low-melting member. The housing has a cylinder bore, a suction chamber, a discharge chamber and a crank chamber. The swash plate is supported in the crank chamber by the drive shaft and inclination angle of the swash plate is adjustable. The piston is reciprocally movably received in the cylinder bore. The bleed passage is formed in the housing in communication with the crank chamber and the suction chamber. The supply passage is formed in the housing in communication with the discharge chamber and the crank chamber. The low-melting member is disposed in the bleed passage so as to restrict fluid flow therethrough and has a lower melting point than the housing. When the low-melting member is melted, an opening of the bleed passage is increased.

摘要： Pistons are accommodated in each cylinder bores of a variable displacement compressor. A swash plate is coupled to the piston for converting rotation of the drive shaft to reciprocation of the pistons. A thrust bearing located between a rotor and a housing of the compressor. The outermost load-bearing points of the thrust bearing are radially farther from the axis of the drive shaft than the axes of the pistons. This permits the thrust bearing to directly receive a reaction forces from the pistons through the rotor without applying a moment to the bearing.
