  Hydraulische Dämpfeinrichtung für Türschliesser 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 der Bohrung 2 ein ringförmiger Flüssigkeitsraum verbleibt. In dem Ventilstift 6 ist eine vorzugsweise
V-förmige Nut 7 vorgesehen, die unterhalb der Wurzel des Ventilstiftes 6 beginnt und deren Querschnitt nach der Spitze des Ventilstiftes 6 zu zunimmt. 



   Bei der in Fig. 1 wiedergegebenen Stellung der Regelschraube 4 ist das Ventil der Dämpfeinrichtung geschlossen und es kann keine Flüssigkeit aus dem Zylinder derselben in den diesen umgebenden Flüssig- keitsraum fliessen. In Fig. 2 ist das Ventil bis zu einem bestimmten Querschnitt geöffnet. Bei zunehmen- der Aussentemperatur, bei der die Viskosität des vorzugsweise als Dämpfflüssigkeit dienenden Öles zu- nimmt, dehnt sich der Ventilschaft 5 und der anschliessende Ventilstift 6 aus, so dass der durch die Nut 7 bestimmte Querschnitt des Flüssigkeitsdurchlasses selbsttätig verkleinert wird und die Dämpfwirkung der
Einrichtung konstant bleibt.

   Nimmt die Viskosität des Öles infolge Sinkens der Aussentemperatur ab, so ziehen der Ventilschaft 5 und der Ventilstift 6 sich zusammen und der   wirksameFlüssigkeitsdurchlass   wird selbsttätig vergrössert. 



   Die in Fig. 4 und 5 dargestellte Ausführungsform unterscheidet sich von der vorstehend beschriebenen lediglich dadurch, dass der Ventilschaft 5 in der Aufnahmehülse 8 der Regelschraube 4 lose drehbar   ange-.   ordnet ist, so dass er an der Drehbewegung der Regelschraube 4 nicht teilnimmt. Unterhalb der Aufnah- mehülse 8 ist der Ventilschaft 5 mit einer Schulter 9 versehen, und zwischen dieser und dem Boden der zweiten Stufe der Bohrung 2 kann eine leichte Feder 10 eingespannt sein. Der Ventilstift   6'hat   in Übereinstimmung mit der dritten Stufe der Bohrung 2 vorzugsweise einen quadratischen Querschnitt und ist wiederum mit der Nut 7 versehen. 



   Bei dieser Ausführungsform ist der Ventilstift   6'in   der dritten Stufe der Bohrung 2 undrehbar geführt, und der Ventilschaft 5 wird durch den Flüssigkeitsdruck und gegebenenfalls durch die Feder 10 gegen die Aufnahmehülse 8 der Regelschraube 4 angedrückt. Die Regelung des Flüssigkeitsdurchlasses ist im übrigen die gleiche wie bei der vorstehend beschriebenen Ausführungsform. 



    PATENT ANSPRÜCHE :    
1. Hydraulische Dämpfeinrichtung für Türschliesser mit einem als Thermostat ausgebildeten und mindestens teilweise aus einem Werkstoff, insbesondere Kunststoff, mit grosser Wärmeausdehnung hergestellten Regelglied, das mit seinem zapfenförmigen Ende in einen Flüssigkeitskanal ragt und in diesem verschiebbar ist, dadurch gekennzeichnet, dass mindestens das im Flüssigkeitskanal angeordnete Ende (6) des Regelgliedes aus einem Werkstoff mit grosser Wärmeausdehnung besteht, in dem Flüssigkeitskanal geführt ist, diesen in der einen Endstellung absperrt und die Fläche seines Querschnittes innerhalb des Kanals nach der Spitze zu abnimmt.

  Hydraulic damping device for door closers
 EMI1.1
 

 <Desc / Clms Page number 2>

 an annular fluid space remains in the bore 2. In the valve pin 6 one is preferably
V-shaped groove 7 is provided, which begins below the root of the valve pin 6 and whose cross section increases towards the tip of the valve pin 6.



   In the position of the regulating screw 4 shown in FIG. 1, the valve of the damping device is closed and no liquid can flow from the cylinder of the same into the liquid space surrounding it. In Fig. 2 the valve is open up to a certain cross section. With increasing outside temperature, at which the viscosity of the oil, which is preferably used as a damping fluid, increases, the valve stem 5 and the adjoining valve pin 6 expand so that the cross-section of the fluid passage determined by the groove 7 is automatically reduced and the damping effect of the
Establishment remains constant.

   If the viscosity of the oil decreases due to a drop in the outside temperature, the valve stem 5 and the valve pin 6 contract and the effective liquid passage is automatically enlarged.



   The embodiment shown in FIGS. 4 and 5 differs from the one described above only in that the valve stem 5 is loosely rotatably mounted in the receiving sleeve 8 of the regulating screw 4. is arranged so that it does not participate in the rotary movement of the regulating screw 4. Below the receiving sleeve 8, the valve stem 5 is provided with a shoulder 9, and a light spring 10 can be clamped between this and the bottom of the second step of the bore 2. In accordance with the third stage of the bore 2, the valve pin 6 ′ preferably has a square cross section and is in turn provided with the groove 7.



   In this embodiment, the valve pin 6 ′ is non-rotatably guided in the third stage of the bore 2, and the valve stem 5 is pressed against the receiving sleeve 8 of the regulating screw 4 by the fluid pressure and possibly by the spring 10. The regulation of the liquid passage is otherwise the same as in the embodiment described above.



    PATENT CLAIMS:
1. Hydraulic damping device for door closers with a control element designed as a thermostat and at least partially made of a material, in particular plastic, with large thermal expansion, which protrudes with its pin-shaped end into a liquid channel and is displaceable in this, characterized in that at least that in the liquid channel arranged end (6) of the regulating member consists of a material with great thermal expansion, in which the liquid channel is guided, this closes off in one end position and the area of its cross-section within the channel decreases towards the tip.
