Abstract
Description
Die Erfindung bezieht sich auf ein Flüssigkeitsventil gemäß Oberbegriff Patentanspruch 1 sowie auf ein Reinigungssystem für Fahrzeugscheiben gemäß Oberbegriff Patentanspruch 12.The invention relates to a liquid valve according to the generic term Claim 1 and a cleaning system for vehicle windows according to the preamble Claim 12.
Beispielsweise bei Reinigungs- oder Waschanlagen bzw. -systemen, die in Fahrzeugen und dabei insbesondere auch in Straßenfahrzeugen zum Ausbringen einer Reinigungsflüssigkeit (Wasser oder Waschwasser mit Reinigungs- und/oder Frostschutzmittel) auf Fahrzeugscheiben verwendet werden, besteht vielfach die Notwendigkeit, insbesondere auch in Abhängigkeit von der Fahrgeschwindigkeit des Fahrzeugs unterschiedliche, aus den Düsen austretende Waschstrahlen zu erzeugen, um optimale Reinigungsergebnisse zu erhalten. Dies wird derzeit in der Regel durch Gruppen unterschiedlicher Düsen erreicht, die durch gesonderte Pumpen einer Versorgungseinheit mit der Reinigungs- oder Waschflüssigkeit versorgt werden.For example in cleaning or Washing systems or systems in vehicles and in particular also in road vehicles to apply a cleaning liquid (water or wash water with cleaning and / or anti-freeze) on vehicle windows are often used, in particular also depending different from the driving speed of the vehicle the nozzles generate escaping washing jets for optimal cleaning results to obtain. This is currently usually differentiated by groups Nozzles reached, by separate pumps of a supply unit with the cleaning or washing liquid be supplied.
Aufgabe der Erfindung ist es, ein Flüssigkeitsventil aufzuzeigen, welches bei einem einfachen Aufbau und hoher Betriebssicherheit gesteuert das Verteilen einer über einen Einlaß zugeführten Flüssigkeit wahlweise auf wenigstens einen ersten Auslaß und auf wenigstens einen zweiten Auslaß ermöglicht.The object of the invention is a liquid valve to show which with a simple structure and high operational reliability controlled distributing one over an inlet supplied liquid optionally on at least one first outlet and on at least one second outlet allows.
Zur Lösung dieser Aufgabe ist ein Flüssigkeitsventil entsprechend dem Patentanspruch 1 ausgebildet. Ein Reinigungssystem für Fahrzeugscheiben ist gemäß Patentanspruch 12 ausgebildet.To solve this problem is a liquid valve trained according to claim 1. A cleaning system for vehicle windows is according to claim 12 trained.
Das erfindungsgemäße Flüssigkeitsventil ermöglicht es, bei einer kleinen, kompakten Bauform und einfacher sowie betriebssicherer Bauweise ohne zusätzliche Steuermittel, insbesondere auch ohne Steuerleitungen usw., allein druckgesteuert den Einlaß wahlweise mit dem wenigstens einen ersten Auslaß oder dem wenigstens einen zweiten Auslaß zu verbinden. Das erfindungsgemäße Flüssigkeitsventil kann in besonders vorteilhafter Weise auch bei Reinigungs- oder Waschanlagen bzw. -Systemen zur Reinigung von Fahrzeugscheiben (Fahrzeugfront- oder Heckscheiben, Scheinwerferscheiben usw.) zur wahlweisen Ansteuerung von Düsen mit unterschiedlicher Strahlform verwendet werden.The liquid valve according to the invention enables with a small, compact design and simple and reliable Construction without additional Control means, especially without control lines, etc., alone pressure controlled the inlet optionally with the at least one first outlet or the at least one to connect the second outlet. The liquid valve according to the invention can in a particularly advantageous manner also in cleaning or washing systems or systems for cleaning vehicle windows (vehicle front or Rear windows, headlight windows, etc.) for optional control of nozzles can be used with different jet shapes.

Die wesentlichen Vorteile des Flüssigkeitsventils
- 1. Für die Steuerung
des Flüssigkeitsventils,
d. h. für
das Umschalten zwischen den beiden Auslässen
6 und8 sind keine zusätzlichen Steuermittel, insbesondere auch keine zusätzlichen Steuerleitungen erforderlich. - 2. Das Umschalten zwischen den beiden Auslässen erfolgt allein durch den Flüssigkeitsdruck.
- 3. Das Flüssigkeitsventil
1 besitzt einen sehr einfachen Rufbau, d. h. es besteht im wesentlichen nur aus der Membrane4 und dem Ventilgehäuse2 . Das Flüssigkeitsventil1 ist daher besonders betriebssicher und kann auch einfach und preiswert gefertigt werden. - 4. Der Auslaß
6 wirkt auch als Rückschlagventil, d. h. im Ruhezustand ist dieser Auslaß geschlossen, so daß auch keine Flüssigkeit in das Ventil zurückfließen kann. - 5. Durch entsprechende Dimensionierung der Verbindungen
10 im Vergleich insbesondere zu dem Auslaß8 bzw. zu dem Querschnitt der mit diesem Auslaß verbundenen Düse oder Düsen läßt sich erreichen, daß in jedem Zustand des Flüssigkeitsventils1 der maximale Flüssigkeitsdruck möglich ist, ohne daß ein Umschalten von dem Zustand der1 in den Zustand der2 erfolgt, das Umschalten vielmehr durch stoßförmiges oder abruptes Erhöhen des Flüssigkeitsdruckes erzielt wird. - 6. Der Strömungswiderstand
in einem System, beispielsweise in dem dargestellten Versorgungssystem
für Reinigungsdüsen
14 und15 wird durch das Einfügen des Flüssigkeitsventils1 in dieses System nur vernachlässigbar erhöht, so daß ein merklicher Druckverlust an den Düsen14 und15 sowie eine merkliche Reduzierung der Durchflußmenge an Reinigungsflüssigkeit nicht eintritt. - 7. Ein weiterer wesentlicher Vorteil besteht in einer kleinen,
kompakten Bauform, so daß ein
Unterbringen des Flüssigkeitsventils
1 insbesondere auch bei einer Reinigungs- oder Waschanlage für Fahrzeugscheiben in unmittelbarer Nähe der Düsen14 und15 kein Problem bereitet.
- 1. For controlling the liquid valve, ie for switching between the two outlets
6 and8th no additional control means, in particular no additional control lines are required. - 2. Switching between the two outlets is done solely by the fluid pressure.
- 3. The liquid valve
1 has a very simple call structure, ie it essentially consists only of the membrane4 and the valve housing2 , The liquid valve1 is therefore particularly reliable and can also be manufactured easily and inexpensively. - 4. The outlet
6 also acts as a check valve, ie in the idle state this outlet is closed so that no liquid can flow back into the valve. - 5. By appropriate dimensioning of the connections
10 compared to the outlet in particular8th or to the cross section of the nozzle or nozzles connected to this outlet, it can be achieved that in any state of the liquid valve1 the maximum fluid pressure is possible without switching from the state of the1 in the state of2 takes place, the switching is rather achieved by abruptly or abruptly increasing the fluid pressure. - 6. The flow resistance in a system, for example in the supply system for cleaning nozzles shown
14 and15 is done by inserting the liquid valve1 only negligibly increased in this system, so that a noticeable pressure loss at the nozzles14 and15 as well as a noticeable reduction in the flow rate of cleaning fluid does not occur. - 7. Another major advantage is a small, compact design, so that the liquid valve can be accommodated
1 especially with a cleaning or washing system for vehicle windows in the immediate vicinity of the nozzles14 and15 no problem.
Die Erfindung wurde voranstehend an einem Ausführungsbeispiel beschrieben. Es versteht sich, daß zahlreiche Änderungen sowie Abwandlungen möglich sind.The invention has been described above on an embodiment described. It is understood that numerous changes as well as modifications possible are.
