A hydrostatic axial piston machine with a swash plate achieves a high power with a compact and simple construction. Two cylinder drums are at some axial distance from one another and are in synchronous rotation. Each drum contains a group of concentric cylindrical borings, between which, and at an angle with respect to the axis of rotation of the axial piston machine there is a rotationally locked circular ring-shaped eccentric disc. The pistons are guided against the disc so that they can move longitudinally in the cylinder bores. Each piston consists of two piston segments having the same diameter oriented coaxially to one another and at some distance from one another. The segments are inserted in cylinder bores which are located opposite one another and are connected to one another by a bridge segment. Two support bodies, one on either side of the eccentric disc, are provided for movement on the eccentric disc along a track. The bridge segments are oriented radially inward toward the axis of rotation (D) of the axial piston machine.

[ I claim:] [1.] A hydrostatic axial piston machine utilizing a swash plate construction said piston machine comprising:two cylinder drums axially spaced from each other and in synchronous rotation, each said cylinder drum comprising a group of concentric cylindrical bores;a circular ring-shaped eccentric disc non-rotatably mounted in said piston machine between said cylinder drums; andpistons guided against said disc for longitudinal movement within said cylindrical bores for the displacement of hydraulic medium or for pressurization by hydraulic medium on both piston ends, each said piston including two piston segments having the same diameter orientated coaxially at a distance from each other, said piston segments inserted oppositely positioned ones of said cylindrical bores, and each said piston including a bridge segment connecting said two piston segments, and said piston including two support bodies positioned on opposite sides of said eccentric disc, said support bodies provided for movement relative to said disc, and wherein said bridge segments are orientated radially inward relative to said concentric cylindrical bores toward the axis of rotation of the axial piston machine.
