Patent ID: 10012218

Abstract:
A variable displacement compressor having means for regulating the minimum inclination angle of a swash plate, a spring urging the swash plate in the inclination angle-increasing direction, and a spring urging the swash plate in the inclination angle-decreasing direction. The swash plate inclination angle is θa as the sum of the urging forces of both springs is zero, when the drive shaft is not rotated; and, when the drive shaft is rotated, its inclination angle is θb at which the sum of moments MS, MF is zero. Moment MS of rotational motion is based on selling the product of inertia in the variable-angle direction of the swash plate to decrease the inclination angle of the swash plate from θa. Moment MF is based on the combined urging force of both springs set so that the inclination angle θb is positioned at a minimum angle at maximum rotational speed.
