Abstract (en)
[origin: EP2388422A2] The drive (1) has a piston acting upon a spring and arranged in a housing (2). The piston cooperates with a driven shaft for opening and/or closing a wing of a window and a door. A pressure equalization device (8) is arranged in the housing that is filled with hydraulic fluid (9). The pressure equalization device has a differential housing (11) whose inner space is in contact with an inner space of the housing by a channel (12) that is arranged in weight (15) of the differential housing. The channel is closed by a stopper, so that vacuum filling of the drive is enabled.
