  • this seal is supported against the spring or on a support element arranged on it, for example a disk.
  • the piston has inserts which support the forces acting on the piston.
  • the toothing part carries the toothing, in which meshes the pinion of the output shaft, and is connected to a static part, which supports the spring force.
  • the toothing part and the static part can also be formed in one piece.
  • the inserts can be made of metal as stamped or bent parts by a Forming process be prepared. But they can also be made of a stable, for example glass fiber reinforced plastic.
  • the inserts can on one side - inside or outside - or on all sides, to form the Koibenform, are covered by plastic, the insertion side can be shaping the piston.
  • the inserts may have formations or extensions that remain free of plastic to introduce forces directly into the inserts, thereby advantageously avoiding these forces deform or damage a less stable plastic. At the inserts imprints can be provided, which increase their stability.
  • One of the inserts may have recesses in which engages the other insert, wherein the parts are fixed together by caulking, bending, or
  • the inserts can also have recesses to arrange valves in the piston, as well as recesses, which are traversed by plastic when spraying the plastic piston, and ensure a secure connection of plastic and insert.
