Definitions

  • stiffening elements which, as has been mentioned above, intends to ensure a contact pressure in the area of the outer edges of the sealing band.
  • Fig. 2b The cross section of the piston seal in a vertical cut is shown in Fig. 2b and its construction in other respects by the perspective view in Fig. 3, wherein 11 indicates a guide pin for simplifying adequate mounting of the seal in the piston.
  • a number, here three, surrounding sealing groves 12 are arranged in order to increase the sealing effect.
  • the invention may be modified within the scope of the annexed claims.
  • the mutual relations between the holding portion and the sealing lip of the piston seal may be different as well as the construction of the protrusion 9 and provision or lack of stiffening elements 10. It is, however, important that the protrusion has such flexibility that it can reach the position shown in the figures as well as a position corresponding to a relieved sealing band.
  • the piston seal is preferably manufactured from a per se known material such as a polyurethane material.
