Abstract (en)

[origin: WO02064933A1] The invention relates to a hydraulic drive for a turning sash, comprising a door-closing element (1) having an eccentrically positioned pinion (6) comprising a circular working curve. Said pinion intermeshes with a toothed rack (5) arranged on a piston (4), causing a particular embodiment of the working curve and the teeth (9) of the toothed rack (5), adapting to an involute toothing of the pinion (6). The invention aims to improve the closing delay in order to obtain an optimum movement sequence of the piston (4) in the housing (2) of the door-closing element (1).
