Abstract (en)
[origin: EP2267259A1] The drive (1) has throttle valves (18, 21, 23, 24) for hydraulically damping movement of a working piston (3). The working piston includes an extension (11) with control rings (12, 13), where an area with a taper (15) is provided between the control rings, An overflow channel (16) provided in the extension opens in the area, where the overflow channel runs out from a front side of the extension and causes loading and unloading of an accumulator piston (6) during a specific angle range of a door or a window. A set of overflow channels (17, 20.1. 20.2, 22.1-22.4) is formed in a housing (2).
