Die vorliegende Erfindung betrifft ein Verfahren, mittels welches sich die Bremswirkung bei Türschließern so regeln läßt, daß der erste Teil des Schließweges der bezüglichen Tür mit größerer, der andere Teil aber mit verringerter Geschwindigkeit vor sich geht, und daß hierbei das Verhältnis dieser beiden Wegteile innerhalb weiter Grenzen beliebig bestimmt werden kann.The present invention relates to a method by means of which the braking effect for door closers can be regulated so that the first part of the closing path of the related The door is moving at a higher speed, but the other part is moving at a lower speed, and that the relationship between these two parts of the route is arbitrary within wide limits can be determined. Bei diesem Verfahren kommen in einem und demselben Bremszylinder zwei Bremsmittel zur Verwendung, welche verschiedene Flüssigkeitsgrade haben. Als dünnflüssigeres dient die Luft, als dickflüssigeres Öl, GlyzerinWith this method, two braking means come in one and the same brake cylinder for use which have different degrees of fluidity. As a thinner the air serves as a thicker oil, glycerine oder dergl. Beide Bremsmittel Luft und öl befinden sich während des Ruhestandes des Türschließers gemeinsam in einem Raum, wobei natürlich die Luft den oberen und die Flüssigkeit den unteren Teil desselben einnimmt.or the like. Both braking means air and oil are together in the same room during the retirement of the door closer, the air being the upper part and the liquid the lower part, of course occupies. Das beim Öffnen der Tür in Bewegung gesetzte Bremsorgan des Türschließers verdrängt die Bremsmittel aus diesem ihrem Ruheraum. Dabei verlassen sie diesen Raum gleichzeitig, beispielsweise durch ein selbsttätig wirkendes Ventil, und füllen schließlich den anderen, den Bremsraum, in welchem sie wiederum übereinander liegen. ■The braking element of the door closer, which is set in motion when the door is opened, is displaced the braking means from this their relaxation room. They leave this room at the same time, for example by automatically acting valve, and finally fill the other, the brake chamber, in which they again lie on top of each other. ■ Aus dem Bremsraum nach dem Ruheraum werden die Bremsmittel aufeinander folgend zurückgeleitet, und zwar erst die Luft und dann die Flüssigkeit. - Dabei erfolgt der Übertritt der Luft naturgemäß schneller und der der Flüssigkeit langsamer. Entsprechend der geringeren Bremswirkung der Luft und der stärkeren der Flüssigkeit geht die Schließbewegung der bezüglichen Tür während ihres ersten Teils schneller und dann langsamer vor sich. Wie groß der eine dieser beiden Teile gegenüber dem anderen sein soll, hängt von dem Füllungsverhältnis der beiden Bremsmittel ab.The braking means are successive from the braking space to the rest space returned, first the air and then the liquid. - The Naturally, the air passes faster and that of the liquid passes more slowly. Corresponding The closing movement goes to the lower braking effect of the air and the stronger of the liquid the relevant door faster during its first part and then more slowly. How big one of these two Parts should be opposite to the other depends on the filling ratio of the two braking means away. In der Zeichnung ist ein Türschließer dargestellt, bei welchem das vorstehend beschriebene Verfahren zum Regeln der Bremswirkung angewendet ist.In the drawing, a door closer is shown in which the above-described Procedure for regulating the braking effect is applied. Der Bremskolben α befindet sich in der Stellung im Zylinder b, welche der geschlossenen Tür entspricht. Dabei nehmen die Bremsmittel den Zylinderraum c ein, weleher durch den Kolben α von dem übrigen Zylinderraum d geschieden ist. Der Kolben a ist zu einem selbsttätig wirkenden Ventil e,f, g ausgebildet, durch welches beide Bremsmittel gemeinsam ihren Weg vom Ruheraum c nach dem Bremsraum d nehmen, wenn sie durch den beim Öffnen der Tür in Bewegung gesetzten Kolben aus ersterem verdrängt werden. Damit der Rücklauf der Bremsmittel nur in der Aufeinanderfolge erfolgen kann, so daß dabei erst die Luft und dann die Flüssigkeit ihre Bremswirkung äußert, ist an höchstgelegener Stelle des Kolbens α eine Rille h als Durchlaß angebracht.The brake piston α is in the position in cylinder b which corresponds to the closed door. The braking means take the cylinder space a c weleher by the piston α from the rest of the cylinder chamber is divorced d. The piston a is designed as an automatically acting valve e, f, g , through which both braking means jointly take their way from the rest area c to the braking area d when they are displaced from the former by the piston set in motion when the door is opened. So that the return of the braking means can only take place one after the other, so that first the air and then the liquid expresses its braking effect, a groove h is provided as a passage at the highest point of the piston α.
