Abstract

Es wird ein Türschließer (1) beschrieben, mit einem Gehäuse (2), einer in dem Gehäuse (2) angeordneten Getriebeanordnung und einem mit der Getriebeanordnung 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) und einen Kolbenraum (14) unterteilt, mit im Gehäuse (2) und im Kolben (8) angeordneten Überströmkanälen (16), und mit in den Überströmkanälen (16) angeordneten Ventilen zur Steuerung des Verhaltens des Türschließers (1). Es ist ein Schaltventil (21) vorgesehen, mit einem in einem Verschlussdeckel (13) des Gehäuses (2) längs seiner Erstreckung verstellbaren Ventilstößel (22), dessen Position den Einsatzpunkt einer Öffnungsdämpfung bestimmt, indem der Ventilstößel (22) eine Ventilkugel (23) von deren zugeordneten Ventilsitz im Überströmkanal (16.2) im Kolben (8) abhebt.

The invention relates to a door closer (1) comprising a housing (2), a gear arrangement arranged in the housing (2) and a piston (8) operatively connected to the gear arrangement, displaceable in a linearly displaceable manner and acted upon by a compression spring (9) Interior of the housing (2) filled with a hydraulic fluid is subdivided into a spring chamber (12) and a piston chamber (14), with overflow channels (16) arranged in the housing (2) and in the piston (8), and in the overflow channels (16). arranged valves for controlling the behavior of the door closer (1). It is a switching valve (21) provided with a in a closure cover (13) of the housing (2) along its extension adjustable valve stem (22) whose position determines the starting point of an opening damping by the valve stem (22) a valve ball (23) from the associated valve seat in the overflow channel (16.2) in the piston (8) lifts.
