Abstract
Description
Aufgabe der Erfindung ist es, das bei den eingangs beschriebenen Waschanlagen verwendete Ventil im Aufbau lind in seiner AnordnungThe object of the invention is that in the case of the washing systems described at the outset valve used in the structure and in its arrangement
derart zu verbessern, daß einige Einzelteile völlig entfallen können und die verbleibenden in ihrem Aufbau wesentlich vereinfacht sind. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kanalabschnitt unterhalb der Düse, der eine größere lichte Weite aufweist als der sich daran anschließende Kanalabschnitt, das Gehäuse eines sich gegen den Druck der Waschflüssigkeit öffnenden Ventils bildet, dessen federbelastetes Verschlußorgan auf der durch die Kanalverengung gebildeten Schulter dichtend aufliegt. Bei der erfindungsgemäßen Ausgestaltung der Waschanlage ist zur Erreichung der Ventilwirkung lediglich ein federbelastetes Verschlußorgan erforderlich.to improve so that some items can be omitted entirely and the remaining are substantially simplified in structure. This task is achieved according to the invention in that the channel section below the nozzle, which has a larger clear width than the adjoining duct section, the housing of a valve that opens against the pressure of the washing liquid forms, its spring-loaded closure member on the one formed by the channel constriction Rests sealingly on the shoulder. In the embodiment of the washing system according to the invention is only a spring-loaded closure member to achieve the valve effect necessary.
Bei einer vorteilhaften Ausführungsform des Erfindungsgedankens wird der pilzförmige Kopf des Verschlußorgans von einer sich an dem Boden der Düse oder der Düsenaufnahme abstützenden Schraubenfeder gegen die durch die Kanalverengung gebildete Schulter gepreßt. Bei dieser Ausführungsform sind lediglich für das Ventil zwei Bauteile erforderlich, die als handelsübliche Teile zu beziehen sind.In an advantageous embodiment of the inventive concept the mushroom-shaped head of the closure member from one to the bottom of the nozzle or the nozzle holder supporting the helical spring against the narrowing of the channel formed shoulder pressed. In this embodiment are only for the valve two components are required, which can be obtained as commercially available parts.
Zur Erhöhung der Funktionssicherheit des Ventils weist der Boden der Düse oder der Düsenaufnahme einen in die Feder hineinragenden Ansatz oder eine das Federende übergreifende Hülse auf. Hierdurch wird das eine Ende der Feder in seitlicher Richtung arretiert. Zur weiteren Unterstützung der Feder ist es zweckmäßig, an die Mantelfläche des das Ventilgehäuse bildenden Kanalabschnitts Vorsprünge anzuformen, die als weitere Führungselemente für die Schraubenfeder dienen.To increase the functional reliability of the valve, the bottom of the Nozzle or the nozzle holder a projection protruding into the spring or a Spring end overlapping sleeve. This moves one end of the spring to the side Direction locked. To further support the spring, it is useful to contact the To form the outer surface of the channel section forming the valve housing projections, which serve as further guide elements for the helical spring.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgedankens.The drawing illustrates an embodiment of the inventive concept.
Das im Schnitt dargestellte Stoßstangenhorn 1 weist die Kanalabschnitte 2, 3 und 4 auf, ie der Zuführung der Waschflüssigkeit zu der Düse 5 dienen. Die Düse 5 ist in eine Düsenaufnahme 6 kugelgelenkartig bewegbar eingesetzt. Die Düseiiaufnahme 6 weist widerhakenartige Vorsprünge auf, mit der sie in den Kanalabschnitt 2 selbstrastend eingesetzt ist. Der Kanalabschnitt 2 ist so tief ausgeführt, daß unterhalb der Düsenaufnahme 6 ein weiterer Raum verbleibt, der das Gehäuse eines Druckventils bildet. Hierin eingesetzt ist das pilzartig ausgebildete Verschlußorgan 7, welches von der sich an der Düsenaufnahme 6 abstützenden Schraubenfeder 8 gegen die durch die Verengung des Kanalabschnittes 3 gebildete Schulter 9 preßt.The bumper horn 1 shown in section has the channel sections 2, 3 and 4, ie serve to supply the washing liquid to the nozzle 5. the Nozzle 5 is inserted into a nozzle holder 6 so as to be movable in the manner of a ball joint. The nozzle holder 6 has barb-like projections with which it self-engages in the channel section 2 is used. The channel section 2 is designed so deep that below the nozzle holder 6 another space remains, which forms the housing of a pressure valve. Here in used is the mushroom-like closure member 7, which is from the on the nozzle holder 6 supporting helical spring 8 against the constriction of the channel section 3 formed shoulder 9 presses.
Zur Arretierung des oberen Endes der Feder 8 ist an den Boden der Düsenaufnahme 6 ein Ansatz 10 angeformt. Als weitere Führungsorgane weist die Mantelfläche des Kanalabschnitts 2 im unteren Bereich längsverlaufende Rippen 11 auf, die sowohl der Feder als auch dem Verschlußorgan eine Führung geben.To lock the upper end of the spring 8 is at the bottom of the Nozzle holder 6, a projection 10 is integrally formed. The jacket surface has as further guide organs of the channel section 2 in the lower region longitudinal ribs 11, which both give the spring as well as the locking member a guide.
