<p>PURPOSE:To perform such inclination control that is stabilized over the whole inclination area by installing a control pressure compensating means provided with a pair of spring members for energizing a swash plate in the inclination decrement direction in opposition to pressure in a control pressure chamber. CONSTITUTION:A control pressure compensating means is constituted of a guide bush 7 and a pair of pressing springs 8, 36. The pressing spring 8, 36. The pressing spring 8 gives force to the guide bush in a direction of making a swash plate inclination larger according to an inclination increase over the whole inclination area of a swash plate 9, while the pressing spring 36 increment pressing action force to the guide bush 7 according to the inclination increase only in and around the max. inclination. With this constitution, even in any area ranging from the max. inclination to the min. one, if control pressure in a control pressure chamber 20a is increased or decreased, a tilt angle of the swash plate 9 is increased or decreased according to this variation, so that the continuous control over discharge displacement is made possible.</p> |
