Door closer, electro-hydraulic damping module and method for influencing a drive movement of a door closer

摘要

Drive device (20) for a relative to a frame member (12) movable wing element (14) such as a door, a window, a flap, in particular in the form of a door closer, with a housing (22) in which a fluid piston (24) mounted axially displaceable configured to transmit a driving force (48) and acting on a first fluid volume (26), having a fluid transducer (66) coupled to the first fluid volume (26) and being adapted to receive fluid energy in a mechanical transducer movement (s) of a transducer member (68) to convert and with an electrical machine (70) which is coupled to the transducer member (68) and which is adapted to the transducer movement (s) in auxiliary electrical energy and / or in Convert heat energy.
