Abstract

PURPOSE: To control discharge rate by a method wherein a rotating body introduces a pressure fluid into a pressure chamber being formed by a support body and a casing and thereby an optional tilt angle of the rotating body to a cylinder block can be obtained.
CONSTITUTION: When a pressure fluid of a fixed pressure is introduced into pressure chambers 123aW123d, the tilt angle α of a rotating body 106 to a cylinder block 114 is increased or decreased to the position where it balances a moment due to the pressure fluid by a moment due to the component force (proportional to the torque of an input-output axis 102) of the gearing force of bevel gears 107a and 107b. That is, the control of the tilt angle α (the control of discharge rate) becomes possible by using the torque of the input-output axis. In addition, the force acting on the rotating body 106 is limited to the liquid pressure caused by a pump and the gearing force applied to the bevel gears 107a and 107b, which makes it possible to employ a fluid bearing 105, thereby a pump motor being made to be small and noises being reduced.
