Abstract

An axial-piston machine of the type in which a prismatic housing, usually of rectangular or square cross section, receives a rotatable cylinder drum, the pistons of which bear against an inclinable control surface. The control surface is formed on a rocker or tilting box which can be tilted about an axis perpendicular to the axis of rotation of the drum. The rocker-setting elements are disposed between the housing bottom and the reaction surface of the rocker (against which the pistons bear), at the corners of a rectangle which closely circumscribes the orbit of the pistons. Consequently, the presence of the rocker-displacing means does not increase the dimensions of the machine over those necessary for a fixed control surface machine.
