<p>A door closer including a casing-like body (1) enclosing a piston member (2), which is movable back and forth according to the movements of a door or the like and which cooperates with a least one closer spring (6), and a closer shaft (4) with a pinion member (5) connected thereto for transmitting the force of the movement of the door or the like to the piston member (2), whereby the pinion member (5) is mounted on the closer shaft (4) eccentrically with regard to its rolling curve (5a). The piston member (2) has a casing-like form and is provided with a rack (3) arranged at its inner surface, having a rolling curve (3a) which is at least substantially linear and which is arranged transversely relative to the direction of movement of the piston member (2). The pinion member (5) is located inside the piston member (2) and has teeth meshing with teeth of the rack (3) so that the force transmitting moment of the pinion member (5) is at its maximum in a position corresponding to the closed position of the door or the like. <IMAGE></p> |
