ABSTRACT OF THE DISCLOSURE The present invention relates to a machine of the axial piston pump type which can be selectively used as a pump or as a motor, which comprises a cylinder drum which is mounted rotatably in a casing and in which working pistons are axially displaceable in working cylinders in axial bores distributed over its periphery, wherein piston rods are con- nected to the working pistons and their other ends run on a control cam which is fastened to the casing, is concentric to the shaft, and extends undulatingly in the axial direction, so that a rotary movement in the cylinder drum is converted into a reciprocating movement of the working pistons, or vice versa, and wherein at least one suction opening and one pressure opening are provided which are fixed to the casing and which in predetermined rotational positions of the cylinder drum are in communication at any given time by way of rotary slide valves with one of the cylinder spaces, which are formed between the working cylinder and the working piston on the side remote from the piston rod, characterized in that the cylinder drum rotates with its free end directly in the medium being pumped.
