Abstract
In a variable piston pump/motor, input/output shafts are pivotably supported by a housing via a shaft support cylinder formed with a spherical outer surface. The housing is disposed so that it can tilt in one direction, pivoting around hydraulic intake/discharge tubes fixed at a position along lines connecting spherical heads of pistons.
