Abstract
The invention relates to an actuator (10) for generating high regulating forces and large regulating distances with a web (12) for the transmission of regulating forces, which actuates an internal pressure, which may be purposefully influenced, in an actuator cavity (14), sealed at least in an indirectly pressure-tight manner, wherein a tubular cavity profile (13) forms the active actuator cavity (14), the shell surface of which is heavily indented in linear form in the effective direction (11) of the regulating forces and in the longitudinal direction of the cavity profile (13) to receive and operate the web (12), and the cavity profile (13) is divided into two mirror-symmetric partial cross-sectional faces (15).
