To make small the size of a bent axis fluid pressure unit wherein a pushing and removing quantity is adjustable.
On a flame 12, a fluid pressure module containing one pair of shafts 25, 26 is rotatably supported, two yokes 14 and 16 are pivoted, each yoke has a surface complementary with respect to other yokes and frames so as to minimize a space which the yokes occupy. On the yoke and the frame, stopper means 50, 52, 54, and 56 for limiting the pivotal movement of the yokes are formed. By each of the yoke, a fluid pressure power unit is supported, each of the yokes is connected with one of the shafts. A control system 62 which has a single part control housing that contains a servo piston is made to pivotally drive the yoke. The servo piston determines the orientation of each of the yokes independently. In the control housing, an integrated port plate for hydraulic control is fixed so as to determine routes of the hydraulic fluid to a plurality positions in the control housing.
