The supporting body presses the sealing body against the housing rear wall and is press fit and weldable there. A positioning cylinder with an outer shell is on the supporting body. An elastomer sealing body positioning cap with an elastomer sealing body is press fit on the outer shell so that the sealing body bears against a supporting body supporting web press-on collar and has a self-supporting supporting arch web, at the pressure space-side end of which is the sealing lip. A cord spring is centrally above the arch web on the sealing body outer circumference in an outer groove.
