Abstract (en)
[origin: WO9729265A1] The invention concerns a door operator in which the fixed coupling between the loading spring (1) and the door piston (3) has been removed. By inserting a hydraulic transmission an embodiment dependent on travel and direction is obtained with at least two different transmission ratios and thus different moment characteristics.
