Abstract (en)
[origin: EP2243558A2] The piston (30) has a piston peripheral wall (32) and a front wall (36) that comprises a shape curved in pressing direction in unloaded condition, where the piston is made of elastic material. The front wall is deformable in condition of smaller curvature under pressure loading, and the front wall is radially expanded in transition region (37) to the piston peripheral wall. A rotating section (50) is formed in the piston peripheral wall with smaller wall thickness. A sealing edge (46) is formed from the front wall to the piston peripheral wall in the transition region.
