Hie Erfindung betrifft selbsttätige Ventile, insbesondere I 'iimpenveiitile, mit einem (innnniring in einer keilförmig:".! Ringnut, der vom Zuflußdruck vom Innern der Nut her beaufschlagt ist und sich beim Offnen nach aul.ien aufweitet. Um den immer höher werdenden Tourenzahlen zu entsprechen und in möglichst kurzer Zeit ein großes Volumen abführen zu können, besteh! das Profil des (jummiriuges eiTmdungsgeinäi.i aus einer Doppellippe, deren Dicke zu den Rändern hin geringer wird. Vorzugsweise hai sie in der Mitte eine Spiralfedereinlage. Durch diese Proliliening biegen sich die Ränder beim Ollnen zurück, so dall der Durchflußquerschnitt nach außen zunimmt und die Strömung sieh infolgedessen bereits innerhalb des Ventils verlangsamt. Das Ventil bietet wegen der Diffusorwirkung geringeren Widerstand als die bisher bekannten (itiinmiringventile, bei denen die Strömung licini Verlassen des Ventils an dem engen Durchtrittskaual zwischen Ring und Keilnut ohne Übergang in den Abllußrauin eintritt.Hie invention relates to automatic valves, in particular I'iimpenveiitile, with an (innnniring in one wedge-shaped: ".! Ring groove, that of the inflow pressure is acted upon from the inside of the groove and expands to aul.ien when it is opened. About him always To correspond to increasing numbers of tours and to dissipate a large volume in the shortest possible time to be able to exist! the profile of the (jummiriuges eiTmdungsgeinäi.i from a double lip, the thickness of which decreases towards the edges. Preferably it has a spiral spring insert in the middle. Because of this prolilation, the Edges back when Ollnen, so that the flow cross-section increases outwards and the flow increases as a result, see already slowed down inside the valve. The valve offers because of the diffuser effect lower resistance than the previously known (itiinmiringventile, in which the flow licini leaving the valve at the narrow causeway between the ring and the keyway without a transition into the drainage area.
Die Abbildungen zeigen das Ventil in geschlossener und in offener Stellung. Hierin bedeuten ι das Ventilgehäuse, _' das Doppel-Lippen-Guminiringventil und 3 die Spiralfeder. Die Art des öffncns ist aus den Abbildungen ohne weiteres erkennbar. Beim Schließen setzt sicli die Mitte der Doppellippc, unterstützt durch die Spiralfeder, zuerst auf den Ventilsitz, nachfolgend die Lippen. Das Ventil kann auch als Rückschlagventil und als Etagenventil verwendet werden.The figures show the valve in the closed and in the open position. Here ι mean that Valve housing, _ 'the double lip rubber ring valve and 3 the coil spring. The type of opening can be easily recognized from the illustrations. At the When closing, the middle of the double lip, supported by the spiral spring, is placed first on the Valve seat, followed by the lips. The valve can also be used as a check valve and as a floor valve be used.
