<p>The invention relates to a differential cylinder (1) for a hydro-mechanical drive for actuating an electric switch, in particular a high-voltage switch, comprising: a first pressure area (3) to be loaded with an operating pressure; a second pressure area (4); and a piston (2) which can be moved in a movement range and which can be moved as a function of the pressure difference between the first and second pressure area (3, 4); characterized in that a damping device is provided which, during a movement of the piston (2) in the direction of the second pressure area (4) in one section (D) of the movement range, provides additional damping against the movement of the piston (2), wherein the additional damping is adjustable.</p> |
