Abstract

The valve (1) has a control section attached to a base body, and a thread provided in the base body. An elevation (6) is present in a retainer for an inserted part (8). The elevation engages in a surface of the inserted part in such a manner that the inserted part is moved in a direction of rotation during an axial rotary movement of the valve. The inserted part is lockably cooperated with a borehole or an internal thread of a door closer, where the outer diameter of the inserted part has a larger diameter than the borehole or the internal thread.

Description

Die Erfindung betrifft ein Regulierventil, das insbesondere in eine mit einem Innengewinde ausgeführte Bohrung eines hydraulischen Türschließers befestigbar ist, mit einem Grundkörper, an den sich ein Regulierabschnitt anschließt, und einem am Grundkörper befindliches Gewinde, welches in das Innengewinde der Bohrung eines hydraulischen Türschließers eingeschraubt wird, wobei der Grundkörper eine Aufnahme mit Erhebungen aufweist, welche in eine Oberfläche eines montierten Einlegeteils eingreifen.The invention relates to a regulating valve which can be fastened in particular in a running with an internal thread bore of a hydraulic door closer, with a base body, followed by a Regulierabschnitt, and a thread located on the body, which is screwed into the internal thread of the bore of a hydraulic door closer wherein the main body has a receptacle with elevations, which engage in a surface of a mounted insert.

In der DE 102 28 872 B4 ist ein Regulierventil für einen Türschließer offenbart, der aus einem Grundkörper und einem Regulierabschnitt besteht. Am Grundkörper befindet sich zur Regulierung des Regulierventils ein Gewinde, das in einer Bohrung des Türschließers eindrehbar ist. Der Regulierabschnitt ist hierbei hülsenartig ausgeführt und über eine Kugelgelenkverbindung mit dem Grundkörper verbunden. Um ein ungewolltes Verdrehen des Regulierventils, insbesondere des Regulierabschnittes, zu verhindern, ist eine am Regulierabschnitt angeordnete Verdrehsicherung vorgesehen, die als Ansatz oder Vorsprung ausgebildet ist. Dieser Ansatz ist in einer Nut innerhalb des Gehäuses des Türschließers längsbeweglich geführt.In the DE 102 28 872 B4 discloses a regulating valve for a door closer, which consists of a base body and a Regulierabschnitt. On the main body is to regulate the regulating a thread that can be screwed into a bore of the door closer. The Regulierabschnitt is in this case designed like a sleeve and connected via a ball joint connection with the body. In order to prevent unintentional rotation of the regulating valve, in particular of the regulating section, an anti-rotation device arranged on the regulating section is provided, which is designed as a projection or projection. This approach is longitudinally movably guided in a groove within the housing of the door closer.

Es ist Aufgabe der vorliegenden Erfindung, ein Regulierventil der eingangs beschriebenen Art zu schaffen, das einfach gestaltet ist, wobei ein ungewolltes, eigenständiges Verstellen des Regulierventils während des Betriebes ausgeschlossen ist.It is an object of the present invention to provide a regulating valve of the type described above, which is simple, with an unwanted, independent adjustment of the regulating valve is excluded during operation.

Zur Lösung dieser Aufgabe wird ein Regulierventil mit den Merkmalen des Anspruches 1 vorgeschlagen. In den abhängigen Ansprüchen sind bevorzugte Weiterbildungen ausgeführt.To solve this problem, a regulating valve with the features of claim 1 is proposed. In the dependent claims preferred developments are carried out.

Dazu ist erfindungsgemäß vorgesehen, in einer Aufnahme, in der ein Einlegeteil montiert wird, mindestens eine Erhebung vorzusehen, wobei die Erhebung in dem in eine Oberfläche eines Einlegeteils eingreifenden Abschnitt kerbförmig ausgeführt ist. Damit kann der erhabene Abschnitt in die Oberfläche eines Einlegeteils eingreifen und als eine Art Mitnehmer für das Einlegeteil fungieren.For this purpose, the invention provides, in a receptacle in which an insert is mounted to provide at least one elevation, wherein the survey is performed in the recess engaging in a surface of an insert section notched. Thus, the raised portion can engage in the surface of an insert and act as a kind of driver for the insert.

Dadurch wird eine klemmende und dichtende Wirkung auch bei axialer Drehbewegung erzielt. Weiterhin wird durch die Klemmwirkung ein unbeabsichtigtes, eigenständiges Lösen oder Verdrehen des Regulierventils vermieden.As a result, a clamping and sealing effect is achieved even with axial rotation. Furthermore, an unintentional, independent loosening or twisting of the regulating valve is avoided by the clamping action.

Von besonderem Vorteil ist, dass das Einlegeteil elastisch verformbar ist. Hierdurch kann die Erhebung auf leichte Art in eine Oberfläche eines Einlegeteils eingreifen. Ebenso können Toleranzfelder überbrückt werden.It is particularly advantageous that the insert is elastically deformable. As a result, the survey can easily engage in a surface of an insert. Likewise, tolerance fields can be bridged.

Weiterhin von Vorteil ist, dass das Einlegeteil mit der Bohrung oder dem Innengewinde des Türschließers dichtend zusammenwirkt. Hierdurch wird die erforderliche Dichtfunktion umgesetzt.Another advantage is that the insert cooperates sealingly with the bore or the internal thread of the door closer. As a result, the required sealing function is implemented.

Eine weitere Verbesserung wird dadurch erzielt, dass die Erhebung, welche in eine Oberfläche eines montierten Einlegeteils derart eingreift, um bei einer axialen Drehbewegung des Regulierventils das Einlegeteil in Drehrichtung zu bewegen, wobei das Einlegeteil mit der Bohrung oder dem Innengewinde des Türschließers klemmend, sowie mit einem Reibmoment versehen, zusammenwirkt. Der Außendurchmesser des Einlegeteils weist einen größeren Durchmesser auf als die Bohrung oder das Innengewinde des Türschließers. Hierdurch erhöht sich das Reibmoment des Einlegeteils an der Bohrung oder an dem Innengewinde des Türschließers.A further improvement is achieved in that the elevation, which engages in a surface of a mounted insert so as to move in an axial rotational movement of the regulating valve, the insert in the direction of rotation, wherein the insert with the bore or the internal thread of the door closer clamping, and provided a friction torque, cooperates. The outer diameter of the insert has a larger diameter than the bore or the internal thread of the door closer. This increases the friction torque of the insert at the bore or at the internal thread of the door closer.

Selbstverständlich können in der Aufnahme mehrere Erhebungen vorhanden sein. Es ist ebenfalls denkbar, dass Erhebungen vorhanden sind, die innerhalb der Aufnahme an gegenüberliegenden Flächen angeordnet sind.Of course, several surveys may be present in the recording. It is also conceivable that elevations are present, which are arranged within the receptacle on opposite surfaces.

Zur Veranschaulichung der Lösung sind nachfolgende Figuren beigefügt.To illustrate the solution, the following figures are attached.
