摘要： In a variable displacement compressor that draws, compresses, and discharges refrigerant gas, the displacement is adjusted by varying the inclination of a cam plate in accordance with the difference between the pressure in a crank chamber and the pressure in cylinder bores. A pressurizing passage connects the crank chamber to a discharge passage. A bleed passage connects the crank chamber to a suction chamber. A displacement control valve is externally controlled and varies the pressure in the crank chamber by adjusting the opening size of either the pressurizing passage or the bleed passage. A suction control valve closes a duct between the suction chamber and an evaporator when the pressure in the crank chamber exceeds a predetermined level to prevent an excessively high pressure in the crank chamber.

摘要： A maximum inclination setting projection comes into contact with a rotary support in a region closer to a point corresponding to a top dead center than an imaginary two-part dividing plane, thereby establishing a maximum angle of inclination of a cam plate. Thus, a hinge mechanism is not required to support any proportion of a compressive load in the region closer to the point corresponding to the top dead center than the imaginary two-part dividing plane when the cam plate is in its maximum angle of inclination. Bulbous parts of guide pins do not come in contact with halves of cylindrical inside surfaces of guide holes closer to the rotary support, and there is made a clearance between the bulbous part of the guide pin and the guide hole and between the bulbous part of the guide pin and the guide hole, interrupting transmission of the compressive load between them.

摘要： A variable displacement compressor that decreases displacement to reduce compression load without imbalancing the rotation of the drive shaft when the rotating speed of the compressor's drive shaft exceeds a predetermined limit value. The compressor includes a pressurizing passage connecting a crank chamber to a discharge chamber. A rotated guide rotates integrally with the drive shaft. The pressurizing passage is opened and closed by a valve body. Orbiting balls, which contact the valve body, are arranged about the axis of the drive shaft and the rotated guide. The balls follow the rotation of the rotated guide and orbit about the axis. The orbiting radius of the balls varies. A spring urges the balls in a direction decreasing the orbiting radius of the balls. When the rotating speed of the drive shaft exceeds the limit value, centrifugal force moves the balls against the force of the spring and increases the orbiting diameter of the balls. This moves the valve body and increases the size of the pressurizing passage.
