Abstract:
1. A variable displacement compressor comprising: a housing including a cylinder bore; a drive shaft supported by the housing; a rotor secured to the drive shaft; a swash plate operatively connected to the rotor and the drive shaft so as to rotate with the rotor and the drive shaft, the swash plate varying an inclination angle relative to the drive shaft; a piston connected to the swash plate so as to reciprocate in the cylinder bore with rotation of the swash plate, a stroke of the piston varying in accordance with the inclination angle of the swash plate; a spring for reducing the inclination angle of the swash plate; and a decelerating mechanism decelerating an inclination speed of the swash plate in a range from a near maximum inclination angle to a maximum inclination angle when the swash plate inclines to increase the stroke of the piston, wherein the decelerating mechanism is arranged between the rotor and the swash plate, wherein the decelerating mechanism includes a decelerating spring, which is provided separately from the spring for reducing the inclination angle of the swash plate, and the spring constant of the decelerating spring is greater than that of the spring for reducing the inclination angle of the swash plate.
