ABSTRACT:
An adjusting drive operated by a pressure medium with a spring-loaded roller diaphragm secured to plates and displaceable within a housing by the pressure medium; the roller diaphragm actuates an adjusting member that is securely connected with a plate and extends out of the housing; in addition to its end positions, the adjusting member is also able to assume at least one intermediate position; the plates are thereby connected with each other by the roller diaphragm while a plate not directly connected with the adjusting member sealingly rests on a ring-shaped abutment projecting out of the inner wall of the housing in the intermediate position of the adjusting member.
