A shutoff structure is provided including an axially extending seal, which opens only in the case of a predetermined pressure difference in the chambers. This seal of the shutoff structure of the overflow channel includes at least two sealing lips, which are separated from one another, have a hook-type profile in their cross section with a radial undercut and are deformable radially to the central axis of the sleeve rubber spring.
