Description
Die Erfindung betrifft selbsttätige Ventile, insbesondere Pumpenventile, mit einem Gummiring ineiner keilförmigen Ringnut, der vom Zuflußdruck vom Innern der Nut her beaufschlagt ist und sich beim Öffnen nach außen aufweitet. Um den immer höher werdenden Tourenzahlen zu entsprechen und in möglichst kurzer Zeit ein großes Volumen abführen zu können, besteht das Profil des Gummiringes erfindungsgemäß aus einer Doppellippe, deren Dicke zu den Rändern hin geringer wird. Vorzugsweise hat sie in der Mitte eine Spiralfedereinlage. Durch diese Profilierung -biegen sich die Ränder beim Öffnen zurück, so daß der Durchflußquerschnitt nach außen zunimmt und die Strömung sich infolgedessen bereits innerhalb des Ventils verlangsamt. Das Ventil bietet wegen der Diffusorwirkung geringeren Widerstand als die bisher bekannten Gummiringventile, bei denen die Strömung beim Verlassen des Ventils an dem engen Durchtrittskanal zwischen Ring und Keilnut ohne Übergang in den Abflußraum eintritt.The invention relates to automatic valves, in particular pump valves, with a rubber ring in a wedge-shaped ring groove, which is affected by the inflow pressure from the inside the groove is acted upon and widens outwards when it is opened. About him always to meet increasing numbers of tours and a large one in the shortest possible time To be able to dissipate volume, the profile of the rubber ring according to the invention consists of a double lip, the thickness of which decreases towards the edges. Preferably has she has a spiral spring insert in the middle. This profiling -bend the edges back when opening, so that the flow cross-section increases to the outside and as a result the flow is already slowing down inside the valve. That Because of the diffuser effect, the valve offers less resistance than the previously known ones Rubber ring valves, in which the flow when leaving the valve at the narrow Passage channel between the ring and the keyway enters the drain space without a transition.
Die Abbildungen zeigen das Ventil in geschlossener und in offener Stellung. Hierin bedeuten r das Ventilgehäuse, 2 das Doppel-Lippen-Gummiringventil und 3 die Spiralfeder. DieArt des Öffnens ist aus den Abbildungen ohne weiteres erkennbar. Beim Schließen setzt sich die Mitte der Doppellippe, 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 closed and open Position. Here r denotes the valve housing, 2 the double-lip rubber ring valve and 3 the coil spring. The type of opening is clear from the figures recognizable. When closing, the middle of the double lip asserts itself through with support the spiral spring, first on the valve seat, then the lips. The valve can can also be used as a check valve and as a floor valve.
