Abstract
An axial piston displacement machine for converting hydraulic work into mechanical work or vice-versa with a plurality of hydraulic cylinders which are rotatably arranged with substantially parallel axes about a joint longitudinal axis, including pistons which are movably arranged in the cylinders and which are in connection with a swivellable plate an adjusting device for setting the swiveling angle of the plate a sleeve which rotates with the cylinders and is arranged outside of the plate, and engagement means for transmitting a torque between the plate and the sleeve on the plate and on the sleeve. An increased efficiency is achieved by including a toothed wheel attached on the outer circumference of the sleeve in order to tap a torque from the sleeve or to introduce a torque to the sleeve.
