Description

Titel: Türschließer mit einem Regulierventil Beschreibung Die vorliegende Erfindung betrifft einen Türschließer mit einem Gehäuse und einem in dem Gehäuse angeordneten Regulierventil.  Title: Door closer with a regulating valve The present invention relates to a door closer with a housing and a regulating valve arranged in the housing.

Die Regulierventile in einem Türschließer regulieren den Ölstrom durch eine Veränderung eines Ringspaltes. Bedingt durch die geringen Ölmengen, die zur Regulierung zur Verfügung stehen, ist das Ventil sehr weit zuzudrehen, um die benötigte hydraulische Drosselung zu erzeugen. Die Breite des Ringspaltes beträgt z. T. nur wenige hundertstel Millimeter (0,01-0,02 mm). Dies wiederum hat den großen Nachteil, dass selbst kleinste im Öl befindliche Schmutzpartikel diesen geringen Spalt verstopfen, da sie nicht durch den Spalt hindurch fließen können. The regulating valves in a door closer regulate the oil flow by changing an annular gap. Due to the small amounts of oil available for regulation, the valve must be turned very far to produce the required hydraulic throttling. The width of the annular gap is z. T. only a few hundredths of a millimeter (0.01-0.02 mm). This in turn has the great disadvantage that even the smallest particles of dirt in the oil clog this small gap, since they can not flow through the gap.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Türschlie- ßer mit einem Regulierventil zu schaffen, bei dem das Regulierventil unanfälliger gegen Verunreinigungen im öl ist. It is therefore an object of the present invention to provide a door closer with a regulating valve in which the regulating valve is less susceptible to contamination in the oil.

Diese Aufgabe wird bei einem Türschließer mit einem Gehäuse und einem in dem Gehäuse angeordneten Regulierventil, erfin- dungsgemäß dadurch gelöst, dass das Regulierventil einen hohlzylindrischen Fortsatz aufweist, der mit zumindest einer die Wandung des Fortsatzes radial durchsetzenden Ausnehmung versehen ist, und dass die Außenseite der Wandung des Fortsatzes im Gehäuse des Türschließers fluiddicht geführt ist.„Fluiddicht" meint This object is achieved according to the invention in a door closer with a housing and a regulating valve arranged in the housing, in that the regulating valve has a hollow cylindrical extension which is provided with at least one recess passing radially through the wall of the extension, and in that the outside of the Wall of the extension in the housing of the door closer is fluid-tight. "Fluidproof" means

BESTÄTIGUNGSKOPIE hier eine weitgehende Abdichtung, wobei kleine Leckagen möglich sind. CONFIRMATION COPY Here is an extensive seal, with small leaks are possible.

Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfin- dung zum Inhalt. The subclaims contain advantageous developments of the invention.

Bevorzugt ist vorgesehen, dass die Außenseite der Wandung des Fortsatzes in einem im Gehäuse gelagerten Dichtring geführt. Alternativ zum Dichtring ist eine annähernd dichte Ausgestaltung der entsprechenden Flächen zwischen dem Fortsatz und dem Gehäuse vorgesehen. Insbesondere ist vorgesehen, dass für die fluiddichte Führung des Fortsatzes die Außenseite der Wandung des Fortsatzes aus einem weicheren oder härteren Material be- steht als die entsprechende Dichtfläche im Gehäuse. It is preferably provided that the outside of the wall of the extension is guided in a sealing ring mounted in the housing. As an alternative to the sealing ring, an approximately dense configuration of the corresponding surfaces is provided between the extension and the housing. In particular, it is provided that, for the fluid-tight guidance of the extension, the outside of the wall of the extension consists of a softer or harder material than the corresponding sealing surface in the housing.

Durch Verschieben des Fortsatzes wird somit die Ausnehmung wahlweise vom Dichtring bzw. der Dichtfläche verschlossen oder ist offen. By moving the extension thus the recess is optionally closed by the sealing ring or the sealing surface or is open.

Besonders bevorzugt kommt für die Dichtflächen die Materialpaarung Kunststoff/Metall, insbesondere Kunststoff/Grauguss oder Messing/Kunststoff, zur Anwendung. Dabei sind jeweils eines der Materiaien am Fortsatz und das jeweils andere Material an der Dichtfläche am Gehäuse vorgesehen. Insbesondere wird ein Fortsatz aus Kunststoff mit einem Gehäuse aus Grauguss oder ein Fortsatz aus Messing mit einem Kunststoffgehäuse gepaart. Particularly preferably, the material pairing of plastic / metal, in particular plastic / gray cast iron or brass / plastic, is used for the sealing surfaces. In each case, one of the Materiaien on the extension and the other material are provided on the sealing surface on the housing. In particular, a plastic extension is mated to a gray cast iron housing or a brass extension to a plastic housing.

Die erfindungsgemäße Lösung bietet den Vorteil, dass durch die Änderung der Geometrie des für die hydraulische Funktion ent- scheidenden Querschnitts weg vom Ringspalt hin zu einem durch eine Ausnehmung und einen Dichtring oder Dichtfläche gebildeten Fenster, sehr viel größere Partikel ungehindert durch das Regulierventil hindurch strömen können, so dass sich das Regulierventil nicht mehr durch die Schmutzpartikel zusetzen kann. The solution according to the invention has the advantage that, due to the change in the geometry of the hydraulic function, outgoing cross-section away from the annular gap towards a window formed by a recess and a sealing ring or sealing surface, much larger particles can flow unhindered through the regulating valve, so that the regulating valve can no longer be clogged by the dirt particles.

Gemäß einer vorteilhaften Weiterbildung weist der Dichtring einen scharfkantigen Querschnitt auf. Nach einer weiteren bevorzugten Ausgestaltung weist die Ausnehmung einen rechteckigen oder quadratischen Querschnitt auf. According to an advantageous development, the sealing ring has a sharp-edged cross section. According to a further preferred embodiment, the recess has a rectangular or square cross-section.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung anhand der Zeich- nungen. Es zeigen: Further details, features and advantages of the invention will become apparent from the following description with reference to the drawings. Show it:

Figur 3 eine Teilansicht eines erfindungsgemäßen Türschließers gemäß einem zweiten Ausführungsbeispiel mit teilweise geöffnetem Regulierventil. Figure 3 is a partial view of a door closer according to the invention according to a second embodiment with partially open regulating valve.

In den Figuren 1 und 2 ist der Bereich eines Gehäuses 1 eines Türschließers gemäß dem ersten Ausführungsbeispiel gezeigt, in dem ein Regulierventil 2 angeordnet ist. Das Regulierventil 2 ist in einer zylindrischen Führung 3 im Gehäuse 1 des Türschließers in Axialrichtung bewegbar geführt und ragt mit einem hohlzylindrischen Fortsatz 4 in einen zylindrischen Kanal 5 hinein. In dem hohlzylindrischen Fortsatz 4 ist eine des- sen Wandung radial durchsetzende Ausnehmung 6 angeordnet. Diese Ausnehmung 6 hat einen rechteckigen oder quadratischen Querschnitt. In the figures 1 and 2, the area of a housing 1 of a door closer according to the first embodiment is shown, in which a regulating valve 2 is arranged. The regulating valve 2 is movably guided in a cylindrical guide 3 in the housing 1 of the door closer in the axial direction and protrudes with a hollow cylindrical extension 4 into a cylindrical channel 5. In the hollow cylindrical extension 4, a recess 6 penetrating radially through this wall is arranged. This recess 6 has a rectangular or square cross-section.

In den Kanal 5, in den der hohlzylindrische Fortsatz 4 des Regu- lierventils 2 hineinragt, ist eine umlaufende Ringnut 7 eingeformt, die einen vorzugsweise rechteckigen oder quadratischen Querschnitt hat. In diese Ringnut 7 ist ein Dichtring 8 mit vorzugsweise einem scharfkantigen, rechteckigen oder quadratischen Querschnitt eingesetzt, der von dem hohlzylindrischen Fortsatz 4 des Regulierventils 2 sowohl in der geöffneten als auch in der geschlossenen Stellung des Regulierventils 2 durchsetzt ist. In the channel 5, in which the hollow cylindrical extension 4 of the regulating valve 2 protrudes, a circumferential annular groove 7 is formed, which has a preferably rectangular or square cross-section. In this annular groove 7, a sealing ring 8 is preferably used with a sharp, rectangular or square cross-section, which is penetrated by the hollow cylindrical extension 4 of the regulating valve 2 both in the open and in the closed position of the regulating valve 2.

Der Dichtring 8 und die Ausnehmung 6 in dem hohlzylindrischen Fortsatz 4 sind so zueinander ausgerichtet, dass durch Drehen des Regulierventils 2 die Größe der Ausnehmung 6, die zum Ausströmen des Öls zur Verfügung steht, variiert und dadurch der Olfluss gesteuert werden kann. The sealing ring 8 and the recess 6 in the hollow cylindrical extension 4 are aligned with each other so that by rotating the regulating valve 2, the size of the recess 6, which is available for outflow of the oil, varies and thereby the Olfluss can be controlled.

Die Ausnehmung kann auch andere Geometrien oder Ausgestal- tungen annehmen. Beispielsweise ist es möglich, im hohlzylindrischen Fortsatz 4 eine Bohrung vorzusehen, von welcher aus der Ölfluss durch eine Querbohrung oberhalb des Dichtrings 8 abfließt kann. Fig. 3 zeigt den Bereich des Gehäuses 1 eines Türschließers gemäß dem zweiten Ausführungsbeispiel, in dem das Regulierventil 2 angeordnet ist. Gleiche bzw. funktional gleiche Bauteile sind in beiden Ausführungsbeispielen mit denselben Bezugszeichen ver- sehen. The recess may also assume other geometries or configurations. For example, it is possible to provide in the hollow cylindrical extension 4 a bore, from which the oil flow can flow off through a transverse bore above the sealing ring 8. 3 shows the region of the housing 1 of a door closer according to the second embodiment, in which the regulating valve 2 is arranged. Identical or functionally identical components are provided with the same reference numerals in both exemplary embodiments.

Im zweiten Ausführungsbeispiel wird auf den Dichtring 8 verzichtet. Gemäß Fig. 3 ist eine Dichtfläche 10 als integraler Bestandteil des Gehäuses 1 ausgebildet. Die fluiddichte Führung erfolgt zwi- sehen einer Außenseite 9 des Fortsatzes 4 und dieser Dichtfläche 10 am Gehäuse 2. Durch entsprechende Materialpaarungen ist diese Führung fluiddicht oder annähernd fluiddicht. Die Dichtfläche 10 endet, insbesondere scharfkantig, mit einer Aufweitung des Kanals 5. In the second embodiment, the sealing ring 8 is dispensed with. According to FIG. 3, a sealing surface 10 is formed as an integral part of the housing 1. The fluid-tight guide takes place between see an outer side 9 of the extension 4 and this sealing surface 10 on the housing 2. By appropriate material pairings, this guide is fluid-tight or approximately fluid-tight. The sealing surface 10 ends, in particular sharp-edged, with a widening of the channel 5.
