Abstract
An integral valve body of elastic material for use in the multiple function valve of a vacuum-operated brake power booster has two roughly circular cylindrical parts which are arranged one behind the other. Two annular portions of the valve body which succeed the cylindrical parts are formed to be particularly rigid. A bellows portion which forms a roll fold and interconnects the annular portions has an S-shaped longitudinal sectional profile in the longitudinal direction of the valve body, the profile being comparatively thin-walled.
