Abstract

Es wird ein Türschließer (1) 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. 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 mittels einer durch die Bewegung der Kolbenstange (7) in Wirkstellung gebrachte Dichtungseinrichtung (29) abgedichtet.

Figure imgaf001
A door closer (1) is described, comprising a housing (2), a gear arrangement arranged in the housing (2) and a piston operatively connected to the gear arrangement by means of a piston rod (7) and displaceable linearly and acted on by a compression spring (9) (8) which divides 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 throttle valves (18, 19, 22) disposed in the transfer passages (16) for controlling the behavior of the door closer. A by the throttle valve (22) for an opening loss effected at a certain door opening angle pressure increase in the spring chamber (12) is opposite the Achsraum (15) immediately before the onset of pressure rise in the spring chamber by means of a movement of the piston rod (7) brought into operative position sealing means (29) sealed.
