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). Ein Schaltventil (21) ist aus einem in einer Aussparung (20) des Gehäuses (2) längs verstellbar angeordneten Magneten (22), einer in einem Überströmkanal (16.2) im Kolben (8) angeordneten Ventilkugel (23) und deren an einer Verjüngung (24) des Überströmkanals (16.2) angeordneten Ventilsitz gebildet, wobei die durch die Position des längs verstellbar angeordneten Magneten (22) bestimmte Lage der Ventilkugel (23) im Überströmkanal (16.2) den Einsatzpunkt einer Öffnungsdämpfung bestimmt, indem die Ventilkugel (23) durch die Verschiebebewegung des Kolbens (8) in Öffnungsrichtung an deren zugeordneten Ventilsitz gelangt und den Überströmkanal (16.2) verschließt.

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). A switching valve (21) consists of a in a recess (20) of the housing (2) longitudinally adjustable magnet (22), one in an overflow channel (16.2) in the piston (8) arranged valve ball (23) and its at a taper ( 24) of the overflow channel (16.2) arranged valve seat, said determined by the position of the longitudinally adjustable magnet (22) certain position of the valve ball (23) in the overflow (16.2) determines the point of application of an opening loss by the valve ball (23) through the Displacement movement of the piston (8) passes in the opening direction of the associated valve seat and the overflow channel (16.2) closes.
