Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem elektromagnetisch betätigten Ventil nach der im Oberbegriff des Anspruchs 1 näher angegebenen Gattung.The invention is based on an electromagnetically actuated valve according to the genus specified in more detail in the preamble of claim 1.

Aufgabe und Vorteile der ErfindungPurpose and advantages of the invention
Die Aufgabe der Erfindung ist es, ein Filterelement so zu gestalten, dass es zusätzlich zur Filterfunktion auch für eine vorteilhafte Strömungsführung genutzt werden kann. Diese Aufgabe wird durch ein Ventil gemäß Anspruch 1 gelöst.The object of the invention is to make a filter element so that it can be used in addition to the filter function for an advantageous flow guidance. This object is achieved by a valve according to claim 1.
Das erfindungsgemäße elektromagnetisch betätigte Ventil mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass bei ihm eine bessere Strömungsführung in der Ventilkammer vorgenommen wird, so dass kreisförmige Wirbelströmungen im Bereich des Ventilsitzes und des Schließgliedes wirksam unterbunden werden und damit auch Luftbläschen nicht im Wirbel gefangen gehalten werden können. Insgesamt wird damit eine schnellere Entlüftung begünstigt, wodurch die Neigung des Ventils zur Geräuschbildung deutlich niedriger liegt. Zudem führt die Integration von Filterelement und Hülsenteil zu einem einzigen Bauelement zu einer kostengünstigen Lösung, da weder zusätzliche Teile noch Montagevorgänge notwendig werden. Weiterhin lässt sich diese Maßnahme ohne weiteres mit bisherigen Lösungen zur Geräuschdämpfung kombinieren.The electromagnetically actuated valve according to the invention with the features of claim 1 has the advantage that in him a better flow guidance is made in the valve chamber, so that circular eddy currents are effectively prevented in the region of the valve seat and the closing member and thus also not trapped air bubbles in the vortex can be. Overall, this favors a faster venting, whereby the tendency of the valve to noise is significantly lower. In addition, the integration of filter element and sleeve part into a single component leads to a cost-effective solution, since neither additional parts nor assembly operations are necessary. Furthermore, this measure can be easily combined with previous solutions for noise reduction.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruch 1 angegebenen Magnetventils möglich, wodurch vor allem eine einfache, kostengünstige und montagefreundliche Bauweise begünstigt wird. Weitere vorteilhafte Ausgestaltungen des Anmeldegegenstandes ergeben sich aus der Beschreibung sowie der Zeichnung.The measures listed in the dependent claims advantageous refinements and improvements of the claim 1 solenoid valve are possible, which especially a simple, inexpensive and easy to install design is favored. Further advantageous embodiments of the subject of the application will become apparent from the description and the drawings.
