Abstract

The piston has a supporting body (2) whose radially outer part has an annular guide part (8) defining a guide surface (12). A separate sealing body is molded onto the support body and has two sealing sections (15) positioned axially on both sides of the guide part and joined by several connecting arms (26) belonging to the sealing body and spaced peripherally apart. The connecting arms extend into holder-ducts (25) axially penetrating the guide part.
