Abstract

Es wird ein Türschließer beschrieben, mit einem Gehäuse (2), einer in dem Gehäuse (2) angeordneten Getriebeanordnung und einem mit der Getriebeanordnung mittels einer Kolbenstange (7) wirkverbundenen, linear verschiebbar geführten, mit einer Druckfeder (9) beaufschlagten Kolben (8), welcher den mit einer Hydraulikflüssigkeit gefüllten Innenraum des Gehäuses (2) in einen Federraum (12) mit einem sich diesem anschließenden Achsraum (15) und einen Kolbenraum (14) unterteilt, mit im Gehäuse (2) angeordneten Überströmkanälen (16), und mit in den Überströmkanälen (16) angeordneten Drosselventilen (18,19,22) zur Steuerung des Verhaltens des Türschließers (1). Ein durch das Drosselventil (22) für eine Öffnungsdämpfung ab einem bestimmten Türöffnungswinkel bewirkter Druckanstieg im Federraum (12) ist gegenüber dem Achsraum (15) unmittelbar vor dem Einsetzen des Druckanstiegs im Federraum (12) mittels einer durch die Bewegung der Kolbenstange (7) in Wirkstellung gebrachten Kolbenstangendichtung (27) abgedichtet.

A door closer is described, having a housing (2), a gear arrangement arranged in the housing (2) and a piston (8) which is operatively connected to the gear arrangement by means of a piston rod (7) and guided in a linearly displaceable manner by a compression spring (9). which subdivides the interior of the housing (2) filled with a hydraulic fluid into a spring chamber (12) with a subsequent axial space (15) and a piston chamber (14), with overflow channels (16) arranged in the housing (2), and with in the overflow channels (16) arranged throttle valves (18,19,22) for controlling the behavior of the door closer (1). A pressure increase in the spring chamber (12) caused by the throttle valve (22) for an opening damping at a certain door opening angle is opposite to the axle space (15) immediately before the onset of pressure rise in the spring chamber (12) by means of a movement of the piston rod (7) Working position brought piston rod seal (27) sealed.
