The actuator (1) has a driven shaft (3) rotatably mounted in a housing (2) for performing an operation of a door leaf. The housing is linearly guided and operatively connected to a piston (5) by the output shaft. The piston comprises a component that is connected with a cylindrical receiving face and a tubular component i.e. thermoformed part. The piston is attached to the receiving face of the tubular component. An inner surface of the housing is arranged at an outer surface of the component and the tubular component. A pressure roll (7) is supported on the component. |
