Abstract

The automatic flow regulator for fluid and gas control consists of a rubber or plastics membrane (6) with several slotted or circular openings and is held at its edges in a metal or plastics housing (5). The membrane is deformed to a greater or lesser extent according to the pressure of the medium. The flow rate, limited by the number and size of the openings, remains constant within a certain pressure range. To reduce flow noise, a projection (10) on the end of the membrane on the outlet side of the channels deflects the fluid or gas stream towards the deflector (11) on the outlet of the regulator (11). The regulator can rapidly and easily be employed in household fittings to effect economies and to reduce flow noise.

Description

"Mengenregler""Volume controller"

Die Erfindung betrifft einen Mengenregler zum selbsttätigen, ohne zusätzliche Hilfsenergien erforderlichen Regeln einer annähernd konstanten Durchsatzmenge in gas- oder flüssige Medien führenden Installationssystemen für Haus und Betrieb, wobei der Regler aus einer in einem Kunststoff- oder Metallgehäuse gehaltenen, elastisch verformbaren Membrane aus Gummi oder Kunststoff mit -entsprechend der gewünschten Durchsatzmenge unabhängig vom örtlichen Druckschlitzartigen oder runden Öffnungen besteht, nach Patent ,,.,,. (amtl. Aktenzeichen P 26 23 191.4).The invention relates to a flow regulator for automatic, without additional auxiliary energies required rules of an approximately constant throughput rate Installation systems for house and business that lead into gas or liquid media, wherein the regulator consists of an elastic element held in a plastic or metal housing deformable membrane made of rubber or plastic with -according to the desired Throughput regardless of the local pressure slot-like or round openings exists, according to patent ,,. ,,. (official file number P 26 23 191.4).

Der Mengenregler gemäß der Hauptanmeldung wird in Systemen installiert, wo es darauf ankommt, konstante Gas- oder Flüssigkeitsmengen, z.B. Wasser oder Kühlmittel, innerhalb einer Zeiteinheit in Abhängigkeit der herrschenden Druckverhältnisse zu fördern oder, z.B. Wasser, sparsam und rationell bei Dusch- und Waschanlagen zu verwenden.The flow regulator according to the main application is installed in systems where it matters, constant gas or liquid quantities, e.g. water or coolant, within a unit of time depending on the prevailing pressure conditions promote or, e.g. water, sparingly and efficiently in shower and washing systems use.

Es werden Volumenregulierungen über mechanische Verstellungen, z.B. Schrauben/Spindeln, Klappen, Durchlaßverengungen, vorgenommen, die den Nachteil haben, daß sie sich während des Betriebes verstellen und vor allem nicht druckunabhängig arbeiten, d.h. unterschiedliche Leistungen je nach Druckbelastung auftreten. Außerdem kommen infolge mechanischer Drosselung Druckschläge und Geräusche in das System.Volume adjustments are made via mechanical adjustments, e.g. Screws / spindles, flaps, passage constrictions, made the disadvantage have that they adjust themselves during operation and, above all, not independent of pressure work, i.e. different performances occur depending on the pressure load. aside from that mechanical throttling causes pressure surges and noises in the system.

Die Aufgabe der Erfindung besteht darin, unter Beibehaltung der Aufgabe der Hauptanmeldung, bei Einsatz des Mengenreglers die zwangsläufig auftretenden Strömungsgeräusche zu eliminieren, d.h. so gering wie möglich zu halten.The object of the invention is, while maintaining the object the main registration, if the flow regulator is used, this is inevitable occurring Eliminate flow noise, i.e. keep it as low as possible.

Diese Aufgabe wird dadurch gelöst, daß -in Strömungsrichtung gesehen- an dem hinteren Ende der Membrane des Reglers eine den Wasserstrahl der Einzeldüsen ablenkende Nase angeordnet ist, die mit der Membrane eine Einheit bildet. This object is achieved in that - viewed in the direction of flow - at the rear end of the membrane of the regulator one the water jet of the individual nozzles deflecting nose is arranged, which forms a unit with the membrane.

Der entscheidende Vorteil des erfindungsgemäßen Mengenreglers gemäß der Hauptanmeldung ist z.B.The decisive advantage of the flow regulator according to the invention according to the main application is e.g.

darin zu sehen, daß er schnell in jedem Haushalt oder Betrieb ohne zusätzliche Umrüstkosten einbaubar ist, und ohne daß das Bild der vorhandenen Armatur optisch negativ beeinflußt wird. Soll z.B. Wasser oder Energie an Mischbatterien sparsam und rationell verwendet werden, kann weil nur noch ein Mengenregler notwendig ist, die Ausflußmenge sehr gering gehalten werden. Spritzen wird vermieden, man erspart zeitraubendes Einregulieren und vermeidet unnötigen Verbrauch. to see that he can quickly find himself in any household or business without additional retrofitting costs can be installed, and without the image of the existing valve optically adversely affected. Should e.g. water or energy on mixer taps Can be used sparingly and efficiently because only one volume regulator is necessary is, the outflow can be kept very low. Splashing is avoided, man saves time-consuming adjustment and avoids unnecessary consumption.

Druckschläge werden weich über die Formveränderung der Menbrane aufgenommen. Pressure surges are softly absorbed by the change in shape of the Menbrane.

Von weiterem Vorteil ist, daß durch die Formveränderung der Membrane die Regelung druckunabhängig ist, und über die Anzahl und Größe der Membranöffnungen eine konstante, mengenmäßig vorher zu bestimmende Flüssigkeit fließt. Hilfsenergie ist nicht erforderlich. Eine ungewünschte Leistungsänderung kann nicht vorkommen. Another advantage is that due to the change in shape of the membrane the regulation is independent of pressure, and on the number and size of the membrane openings a constant, quantitatively determined beforehand liquid flows. Auxiliary power not necessary. An undesired change in performance cannot occur.

Die Vorteile der Erfindung bestehen darin, daß ohne große konstruktive Veränderung des Mengenreglers die durch den Mengenregler auftretenden Strömungsgeräusche verhindert werden können. Die vorteilhafte Formgestaltung, die åch in der Praxis bewährt hat, braucht dabei nicht verändert zu werden. The advantages of the invention are that without major structural change in the volume controller caused by the volume controller Flow noises can be prevented. The advantageous design that å has proven itself in practice, does not need to be changed.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird wie folgt näher beschrieben. Es zeigen: Fig. 1 den Mengenregler im Teilschnitt Fig. 2 den Mengenregler im vergrößerten Teilschnitt, im eingebauten Zustand, Fig. 3 eine Draufsicht der Fig. 1.An embodiment of the invention is shown in the drawing and is described in more detail as follows. The figures show: FIG. 1 the flow regulator in partial section FIG. 2 shows the flow regulator in an enlarged partial section, in the installed state, FIG. 3 is a plan view of FIG. 1.

Der Mengenregler 1 besteht aus einem Gummi- oder Kunststoffmembranteil 6 mit mehreren schlitzartigen oder runden Öffnungen 8, das von der Eingangsseite 7 her druckbeaufschlagt wird. Die Membrane 6 weist eine bestimmte Menge von Durchlaßöffnungen 8 auf und befindet sich in einem Metall- oder Kunststoffgehäuse 5. Entsprechend der Druckstärke wird die Membrane 6 mehr oder weniger stark verformt. Die Durchflußmenge, abhängig von Anzahl und Größe der Öffnungen 8, bleibt innerhalb eines nach oben begrenzten Druckbereiches konstant. Am -in Strömungsrichtung gesehen- hinteren Ende der Membrane 6 ist eine Nase 9 angebracht, deren Aufgabe es ist, mit ihren äußeren Kanten 10 den Medienstrahl, hervorgerufen durch die Öffnungen 8, sbzulenken und durch den Perlator 11 aus dem Regler 1 abzuführen.The volume regulator 1 consists of a rubber or plastic membrane component 6 with several slot-like or round openings 8, which is from the entrance side 7 is pressurized forth. The membrane 6 has a certain number of passage openings 8 and is located in a metal or plastic housing 5. Correspondingly the pressure strength, the membrane 6 is more or less deformed. The flow rate, depending on the number and size of the openings 8, remains within one to the top limited pressure range constant. At the rear end when viewed in the direction of flow the membrane 6 is attached to a nose 9, the task of which is with their outer Edges 10 to steer the media jet caused by the openings 8 and to be discharged from the regulator 1 through the aerator 11.
