<p>The invention relates to a door closer, comprising a door closer housing, a drive unit which can be coupled to a door by means of a door closer shaft and a linkage and is disposed in the door closer housing, and a hydraulic damping unit, which has a damping piston which is guided in a damping cylinder of the door closer housing and is operatively connected to the drive unit. Said damping piston cooperates with a first oil discharge channel associated with a rapid door closing movement and a second oil discharge channel associated with a slow door closing movement, wherein the first and second discharge channels are disposed one after the other and wherein the first discharge channel, as seen looking in the direction of movement of the damping piston, is disposed downstream of the second discharge channel.</p> |
