Me Erfindung betrifft einen Ventilkörper und stellt eine Verbesserung des Ventilkörpers gemäß dem Patent „o.o l (Patentanmeldung A 33.869 XIl/47g) dar.Me invention relates to a valve body and represents an improvement of the valve body according to the patent "oo l" (patent application A 33.869 XIl / 47g).

Das genannte Patent bezieht sich auf einen Ventilkegel, dessen Abdichtfläche toη einer Dichtung aus Gummi oder einem ähnlichen elastischen Material gebildet wird, die, abgesehen von dem Teil, der am Sitz aufliegt, im wesentlichen völlig von starren Wänden umgeben und derart angordnet ist, daß der gesamte Schließdruok über sie auf den Sitz einwirkt, indem eine starre Muffe sie umgibt und derart angeordnet ist, daß sie gegenüber der Dichtung und dem Ventilkörper beweglich ist und bei geschlossenem Ventilkörper gegen die Wirkung eines elastischen Teiles nachgeben kann. Kennzeichnend für diesen Ventilkörper ist gemäß dem Hauptpatent, daß die Dichtung den elastischen Teil durch einen Abschnitt bildet, der hinter einem an der umgebenden Muffe vorgesehenen Widerlager liegt» Hierdurch wird die Dichtung in der Herstellung sehr billig, arbeitet gut und weist eine große Haltbarkeit auf0 Said patent relates to a valve cone, the sealing surface of which is formed of a seal made of rubber or a similar elastic material, which, apart from the part that rests on the seat, is essentially completely surrounded by rigid walls and arranged in such a way that the entire closing pressure acts on it on the seat by a rigid sleeve surrounding it and being arranged in such a way that it is movable with respect to the seal and the valve body and can yield when the valve body is closed against the action of an elastic part. According to the main patent, this valve body is characterized by the fact that the seal forms the elastic part through a section which is located behind an abutment provided on the surrounding sleeve »This makes the seal very cheap to manufacture, works well and has a long service life 0

Indessen hat es sich gezeigt, daß man unter gewissen Bedingungen keine befriedigende Dichtung erhält, und zwar besonders dann, wenn das Ventil für Warmwasser benutzt wird. Wenn der Wai§wasserhahn geöffnet wird und so lange offenbleibt, daß das Ventilgehäuse durchwärmt wird und dann geschlossen wird, entsteht eine Undichtigkeit in der Dichtung, wenn das Ventilgehäuse sich wieder abkühlt. Dies ist der geringen lederung zuzuschreiben, die die Dichtung des Ventilkörpers aufweist·It has been shown, however, that under certain conditions does not receive satisfactory poetry, especially when the valve is used for hot water. If the water tap is opened and remains open so long that the valve housing is heated and then closed, a leak occurs in the seal when the valve housing cools down again. This is the minor leather attributable to the seal of the valve body

Dieser Nachteil wird gemäß der vorliegenden Erfindung dadurch, beseitigt, daß der Veirbilkörper hinter der Dichtung mit einer Aussparung versehen wird, die den Haum für die Federung der Dichtung erhöht. Bei Versuchen hat es sich gezeigt, daß diese einfache Maßnahme eine wesentlich verbesserte Federung der Dichtung mit sich bringt»This disadvantage becomes in accordance with the present invention thereby eliminating the fact that the vortex body is behind the seal is provided with a recess that the Haum for the Seal suspension increased. Tests have shown that this simple measure is a significantly improved one Brings springiness of the seal with it "

Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung veranschaulicht o An embodiment of the invention is illustrated in the drawing o

Der Ventilkörper ist mit 1 und der Ventilsitz mit 2 bezeichnet. Der Ventilkörper ist mit einer ringförmigen Höhlung versehen, in die eine Gummidichtung 3 mit der Muffe 4 eingelegt ist ο Die Dichtung 3 und die Muffe 4 werden von der Unterlegscheibe 5 und der Mutter 6 festgehalten. Die Dichtung 3 weist an ihrer über der Muffe 4- liegenden äußeren Kante eine A-bschrägung 7 auf.The valve body is designated with 1 and the valve seat with 2. The valve body has an annular cavity in which a rubber seal 3 with sleeve 4 is inserted ο The seal 3 and sleeve 4 are removed from the washer 5 and the mother 6 held. The seal 3 has a bevel 7 on its outer edge lying above the sleeve 4.

Erfindungsgemäß ist im Ventilkörper 1 über der Dichtung Q 3 eine ringförmige Aussparung 8 vorgesehen, die über der Muffe angebracht ist und die Federung der Dichtung 3 verbessert.According to the invention, an annular recess 8 is provided in the valve body 1 above the seal Q 3, which recess is provided above the sleeve and improves the resilience of the seal 3.
