Abstract (en)

[origin: WO8703926A1] A piston is used in axial piston machines, in particular short-stroke axial piston machines of the type having an inclined disk and a through-bore in the axis of symmetry of the piston. In order to obtain a piston having a dead volume and a mass as reduced as possible and which is easy to manufacture, the piston is provided, in the axial direction, only in a first zone turned towards the free end of the cylinder, i.e. the ball-and-socket joint of the cylinder, and in a second zone, at its other end, with the outer profile that corresponds to the cross-section of the cylinder. In the intermediary zone lying between its two ends the piston has a considerably smaller cross-section.
