Abstract
Die vorliegende Erfindung betrifft einen Türschließer mit einem Gehäuse (1) und einem in dem Gehäuse (1) angeordneten Regulierventil (2), wobei das Regulierventil (2) einen hohlzylindrischen Fortsatz (4) aufweist, der mit zumindest einer die Wandung des Fortsatzes (4) radial durchsetzenden Ausnehmung (6) versehen ist, und wobei die Außenseite (9) der Wandung des Fortsatzes (4) im Gehäuse (1) des Türschließers fluiddicht geführt ist.The present invention relates to a door closer with a housing (1) and a regulating valve (2) arranged in the housing (1), wherein the regulating valve (2) has a hollow-cylindrical extension (4) which is connected to at least one wall of the extension (4) ) radially passing recess (6) is provided, and wherein the outer side (9) of the wall of the extension (4) in the housing (1) of the door closer is guided in a fluid-tight manner.
Description
Die vorliegende Erfindung betrifft einen Türschließer mit einem Gehäuse und einem in dem Gehäuse angeordneten Regulierventil. The present invention relates to a door closer having a housing and a regulating valve disposed 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 Türschließer 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, erfindungsgemäß 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 hier eine weitgehende Abdichtung, wobei kleine Leckagen möglich sind. This object is achieved in a door closer with a housing and a regulating valve arranged in the housing, according to the invention that the regulating valve has a hollow cylindrical extension which is provided with at least one radially passing through the wall of the extension recess, and that the outside of the wall of the Extension is performed in the housing of the door closer fluid-tight. "Fluid-tight" here means a substantial seal, with small leaks are possible.
Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt. The dependent claims have advantageous developments of the invention to the content.
Bevorzugt ist vorgesehen, dass die Außenseite der Wandung des Fortsatzes in einem im Gehäuse gelagerten Dichtring geführt It is preferably provided that the outside of the wall of the extension is guided in a sealing ring mounted in the housing
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 besteht als die entsprechende Dichtfläche im Gehäuse. 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 guide of the extension, the outside of the wall of the extension 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 Materialen 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 materials on the extension and the respective 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 entscheidenden 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, as a result of the change in the geometry of the cross-section crucial for the hydraulic function, from the annular gap to a window formed by a recess and a sealing ring or sealing surface, much larger particles can flow unhindered through the regulating valve that the regulating valve can no longer be clogged by the dirt particles.
Gemäß einer vorteilhaften Weiterbildung weist der Dichtring einen scharfkantigen Querschnitt auf. According to an advantageous development, the sealing ring has a sharp-edged cross section.
Nach einer weiteren bevorzugten Ausgestaltung weist die Ausnehmung einen rechteckigen oder quadratischen Querschnitt auf. According to a further preferred embodiment, the recess has a rectangular or square cross-section.
