The door actuator comprises a housing (2) and a driven shaft (3) mounted in the housing in a rotationally movable manner for actuating a door leaf. A piston (5) is linearly guided in the housing and is operatively connected with the driven shaft. The piston comprises a bearing scaffold and a tubular cladding component enclosing the scaffold. An outer surface of the cladding component is guided to an inner surface of the housing. |
