Abstract
An axial piston device ( ) of the bent axis type including a housing ( ), a main shaft ( ) defining an axis of rotation (A), a cylinder barrel ( ) defining a plurality of mutually parallel cylinders ( ), and a piston ( ) reciprocably disposed in each cylinder ( ). The cylinder barrel is mounted to be pivotable within the housing relative to the axis of rotation (A). A universal type connection ( ) is operable to transmit rotational movement between the main shaft ( ) and the cylinder barrel as the cylinder barrel pivots through its range of motion between a minimum displacement and a maximum displacement (FIG. 2) relative to the axis of rotation (A). A plurality of connecting rods ( ) is arranged to correspond generally to the cylinders, each connecting rod including a ball portion ( ) pivotably received within a socket member ( ) fixed relative to the main shaft ( ). Each socket member ( ) defines an axis ( ), each axis being oriented outwardly at an acute angle relative to the axis of rotation (A), thus permitting an increase in the maximum stroke angle (FIG. 3) of the cylinder barrel relative to the axis of rotation.
