<p>The invention relates to an electromechanical swing leaf operator having a door closer ( 1 ) with an eccentrically supported pinion ( 6 ) that presents a circular rolling curve and meshes with a toothed rack ( 5 ) being disposed at a piston ( 4 ), whereby a particular execution of the rolling curve and of the teeth ( 9 ) of the toothed rack ( 5 ) in adaptation to a toothing of the pinion ( 6 ) is achieved. With the intention to realize an optimized moving course of the piston ( 4 ) in the housing ( 2 ) of the door closer ( 1 ) an improved execution of the delayed closing operation is provided.</p> |
