Abstract:
An axial piston device of the bent axis type comprising a housing, a main shaft rotatably supported relative to said housing, and defining an axis of rotation, a cylinder barrel rotatably disposed within said housing, said cylinder barrel defining a plurality of mutually parallel cylinders, a piston reciprocably disposed in each cylinder for axial displacement therein, said cylinder barrel being mounted to be pivotable within said housing relative to said axis of rotation; a universal type connection operable to transmit rotational movement between said main shaft and said cylinder barrel as said cylinder barrel pivots through its range of motion between a minimum displacement and a maximum displacement relative to said axis of rotation; a plurality of connecting rods arranged to correspond generally to said cylinders, each connecting rod having a pivotable connection to one of said pistons and including a ball portion pivotably received within a socket member fixed relative to said main shaft; characterized by:(a) each of said socket members defining an axis, each axis being oriented outwardly at an acute angle relative to said axis of rotation, thus permitting an increase in said maximum displacement of said cylinder barrel relative to said axis of rotation.
