Description
Die Erfindung betrifft ein Lärmschutz- und Belüftungsventil für eine Otoplastik, mit einem Ventilgehäuse aus Kunststoff und einem in diesem angeordneten Ventilkörper aus Metall, der einen im wesentlichen zylindrischen Einschraubteil mit axialen Luftkanälen und einen konischen Teil aufweist, welcher mit einer Durchtrittsöffnung des Ventilgehäuses einen Luftdurchtrittsspalt begrenzt. The invention relates to a noise protection and ventilation valve for an earmold, with a valve housing made of plastic and a valve body made of metal arranged therein, which has a substantially cylindrical screw-in part with axial air channels and a conical part which, with a passage opening of the valve housing, delimits an air passage gap.
Bei Ventilen dieser Art hat sich in der Praxis das Problem ergeben, daß der in das Ventilgehäuse eingeschraubte Ventilkörper im Gebrauch die Tendenz hat, sich infolge von Bewegungen, Erschütterungen u.dgl. zu verstellen, wodurch sich der Luftdurchtrittsspalt unerwünscht verändert.In practice, valves of this type have the problem that the valve body screwed into the valve housing tends to become displaced during use as a result of movements, vibrations, etc., causing undesirable changes in the air passage gap.
Die Erfindung schafft nun eine Abhilfe für das vorstehend geschilderte Problem dadurch, daß in dem Einschraubteil zwischen zwei Gewindeabschnitten desselben eine Umfangsausnehmung zur Aufnahme eines O-Ringes aus elastischem Material ausgebildet ist, der an der Innenwand des Ventilgehäuses unter Vorspannung angreift.The invention now provides a remedy for the problem described above in that a circumferential recess is formed in the screw-in part between two threaded sections thereof for receiving an O-ring made of elastic material, which engages the inner wall of the valve housing under prestress.
Auf diese Weise wird jeglicher Tendenz des Ventilkörpers zu einer unbeabsichtigten Verstellung entgegengewirkt, weil der O-Ring selbsttätige Drehbewegungen des Ventilkörpers hintanhält.In this way, any tendency of the valve body to unintentionally adjust is counteracted, because the O-ring prevents the valve body from rotating automatically.
Die Erfindung wird nachfolgend an einem Ausführungsbei-0 spiel unter Bezugnahme auf die Zeichnungen näher erläutert, in welchen die Fig.l und 2 jeweils einen Teilaxialschnitt durch ein Ventilgehäuse gemäß der Erfindung mit einem in dieses eingeschraubten Ventilteil in zwei unterschiedlichen Ventilstellungen zeigt.The invention is explained in more detail below using an exemplary embodiment with reference to the drawings, in which Figs. 1 and 2 each show a partial axial section through a valve housing according to the invention with a valve part screwed into it in two different valve positions.
Das in Fig.l gezeigte Ventil ist für eine nicht gezeigte Otoplastik bestimmt, die in den Gehörgang eines menschlichen Ohres eingesetzt wird, um dieses vor Schäden durch Lärmeinwirkung zu schützen. Die Otoplastik ist aus Kunststoff gegossen und der Form des Gehörganges angepaßt. In einem Kanal der Otoplastik ist ein Ventil gemäß der Erfindung angeordnet, das aus einem in den Kanal formschlüssig eingesetzten Ventilgehäuse 1 aus Kunststoff und aus einem in dieses eingeschraubten " Ventilkörper 2 aus Metall besteht.The valve shown in Fig. 1 is intended for an earmold (not shown) that is inserted into the ear canal of a human ear to protect it from damage caused by noise. The earmold is cast from plastic and adapted to the shape of the ear canal. A valve according to the invention is arranged in a channel of the earmold, which consists of a plastic valve housing 1 that is inserted into the channel in a form-fitting manner and a metal valve body 2 that is screwed into it.
Wie die Zeichnung zeigt, ist das Ventilgehäuse im wesentlichen kegelstumpfförmig ausgebildet. Das Innere des Ventilgehäuses 1 weist einen zylindrischen Abschnitt 1' und einen daran anschließenden kegelförmigen Abschnitt 1'' auf. In ein Schraubgewinde des zylindrischen . Abschnitts 1' ist der Ventilkörper 2 eingeschraubt, der einen Gewindeeinschraubteil 2' mit zwei Gewindeabschnitten 2'' und einer zwischen diesen vorgesehenen Umfangsausnehmung 2''' für einen O-Ring 3 aus elastischem Material aufweist. An den Einschraubteil 2' schließt ein in den kegelförmigen Abschnitt 1'' ragen-As the drawing shows, the valve housing is essentially truncated cone-shaped. The interior of the valve housing 1 has a cylindrical section 1' and an adjoining conical section 1'' . The valve body 2 is screwed into a screw thread of the cylindrical section 1', which has a threaded screw-in part 2' with two threaded sections 2'' and a circumferential recess 2''' provided between them for an O-ring 3 made of elastic material. The screw-in part 2' is adjoined by a
TVTV
der konischer Teil 2 an, welcher mit der kleineren Kegelbasis des Ventilgehäuses 1 einen einstellbaren Öffnungs-Luftspalt I''' bildet. Im Gewindeeinschraubteil 2' sind zwei nicht gezeigte, axial verlaufende Bohrungen für den Luftdurchtritt zum Öffnungs-Luftspalt I''' ausgebildet. Der O-Ring 3 hat größeren Außenumfang als der Innenumfang des Ventilgehäuses, so daß er am Ventilgehäuse unter Vorspannung angreift und jegliche unbeabsichtigte Schraubbewegung des Ventilkörpers 2 vermeidet.the conical part 2, which forms an adjustable opening air gap I''' with the smaller cone base of the valve housing 1. In the threaded screw part 2', two axially extending holes (not shown) are formed for the passage of air to the opening air gap I'''. The O-ring 3 has a larger outer circumference than the inner circumference of the valve housing, so that it engages the valve housing under pre-tension and prevents any unintentional screwing movement of the valve body 2.
Durch die gezeigte Konstruktion wird eine sichere Anordnung der Ventilkörper im Gehäuse erzielt.The design shown ensures a secure arrangement of the valve bodies in the housing.
