The device has a valve (14) provided in a connection that is conducted from a cylinder chamber (4) to another cylinder chamber (3), where the connection facilitates a gas flow from the cylinder chamber (4) to the cylinder chamber (3) and is lockable in an opposite flow direction by the valve. The two cylinder chambers are connected with each other by a manually operable interconnection valve (16), where a flow regulator is arranged in the connection. The valve exhibits a radial circumferential slot (6) that is connected with the cylinder chamber (3). |
