Piston for an axial piston machine

摘要

The piston has a cavity that closed in a pressure-tight way in the interior of a piston portion (4). The webs are left between several chambers into which the cavity is divided. The hollow and cylindrical chambers are arranged beside the other in cross-section of the piston portion and/or extended axially in the piston portion. The piston portion is provided with an integral base element in which the chambers are incorporated, and wherein the chambers are closed towards a working surface of the piston by one or more closure elements. An independent claim is included for the method for manufacturing piston for axial piston machine.
