Description

"Atemschutzmaske" Die Erfindung bezieht sich auf eine Atemschutzmaske mit einem Nahrungsaufnahmeventil, durch das hindurch eine Kanüle eines Nahrungsmittelbehälters in das Maskeninnere eingeführt werden kann und das einen Führungskanal für die Kanüle, einen Ventilsitz und einen durch Federkraft gegen den Ventilsitz gedrückten und beim Einführen der Kanüle durch diese vom Ventilsitz entfernbaren, um eine Achse verschwenkbaren Ventilkörper aufweist. "Respirator" The invention relates to a respirator with a food intake valve through which a cannula of a food container can be inserted into the inside of the mask and a guide channel for the cannula, one valve seat and one by spring force against the valve seat pressed and when inserting the cannula through this can be removed from the valve seat, Has pivotable valve body about an axis.

Bei einer bekannten Maske dieser Art ist der Ventilkörper eine Klappe, die um die Achse schwenkbar gelagert ist. Diese Konstruktion bedingt eine sehr genaue Justierung; die kleinsten Verschiebungen der Schwenkachse parallel zur Achse des Führungskanals bzw. geringfugige Abnutsungen der Dichtungselemente führen bereits zu Undichtigkeiten.In a known mask of this type, the valve body is a flap, which is pivotably mounted about the axis. This construction requires a very precise one Adjustment; the smallest shifts of the swivel axis parallel to the axis of the Guide channel or slight Abnutsungen the sealing elements already lead to leaks.

Der Erfindung liegt die Aufgabe zugrunde, das Nahrungsaufnahmeventil derart auszubilden, daß bei der Herstellung größere Fertigungstoleranzen möglich Sind und daß sich Abnutzungserscheinungen bei häufigem Gebrauch nicht nachteilig auf die Dichtung auswirken.The invention is based on the object of the food intake valve to be designed in such a way that greater manufacturing tolerances are possible during manufacture Are and that signs of wear and tear with frequent use are not disadvantageous affect the seal.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Ventilörper eine Kugel dient, die mit Spiel in einer parallel zum Ventilsitz verlaufenden Ebene an einem um die Achse verschwenkbaren Rahmen gelagert ist In der einzigen Figur der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt.According to the invention, this object is achieved in that the valve body a ball is used with play in a plane running parallel to the valve seat is mounted on a pivotable frame about the axis in the single figure the drawing shows an embodiment according to the invention.

Das Ventil besteht aus einem Ventilsitzgehäuse 1 mit einet Ventilsitz 2, einer Schraubkappe 3, einer Kugel 4 mit einem Rahmen 5, einem Einführungsschacht 6 und einem diesen uRerdeckenden Schraubverschluß 7. Im Einführungsschacht 6 befindet sich ein O-Bing 8, der gewährleistet, daß das System bereits zwischen Einführungskanüle und Einführungsschacht abgedichtet ist, bevor die Kugel durch das Weiterführen der Kanüle geöffnet wird. Die Kugel 4 ist über eine Welle 9 mit Spiel in zwei zueinander senkrechten Richtungen, also in einer Ebene, an dem Rahmen 5 gelagert. @The valve consists of a valve seat housing 1 with a valve seat 2, a screw cap 3, a ball 4 with a frame 5, an insertion shaft 6 and a screw cap 7 covering this uRerdeckenden. Located in the insertion shaft 6 an O-Bing 8, which ensures that the system is already between the insertion cannula and insertion shaft is sealed before the ball is continued by the Cannula open will. The ball 4 is on a shaft 9 with play in two mutually perpendicular directions, that is to say in one plane, on the frame 5 stored. @
