Description

Die Erfindung betrifft ein Ventil nach der Gattung des Oberbegriffs des Anspruchs 1.The invention relates to a valve according to the genus of Preamble of claim 1.

Ein derartiges Ventil ist beispielsweise aus der DE-19 52 458-A1 vorbekannt. Dadurch, daß das Ventil im Wesentlichen aus Kunststoff besteht, wird eine Korrosion des Ventils durch eine korrodierende Flüssigkeit, zum Beispiel durch eine peroxidhaltige Flüssigkeit (Haarfärbeprodukt), verhindert. Hierbei ist ein Abgabestutzen und ein Befestigungskragen mittels einer Druckfeder einteilig verbunden. Eine Abstimmung der Druckfeder auf erforderliche Stellkräfte ist nur durch eine kostenintensive Werkzeugänderung oder Werkzeugneuherstellung möglich.Such a valve is for example from DE-19 52 458-A1 previously known. The fact that the valve in Is essentially made of plastic, corrosion of the Valve through a corrosive liquid, for example through a liquid containing peroxide (hair coloring product), prevented. Here is a delivery nozzle and a Fastening collar in one piece using a compression spring connected. Adjustment of the compression spring to the required one Actuators is only through a cost-intensive Tool change or new tool production possible.

Der Gegenstand des Anspruchs 1 unterscheidet sich davon dadurch, daß der Abgabestutzen von einem Zylinderteil (Schlauchteil) aus Elastomer umschlossen ist, der eine nach oben hin als eine Druckfeder wirkende Verlängerung aufweist. Dadurch können kostengünstig entsprechende Halbzeuge verwendet werden. Eine weitere vorteilhafte Weiterbildung der Erfindung geht aus dem Unteranspruch hervor.The subject matter of claim 1 differs from the fact that the delivery nozzle of a cylinder part (hose part) made of elastomer is the one that acts upwards as a compression spring Has extension. This can be inexpensive appropriate semi-finished products are used. Another advantageous development of the invention is based on the Subclaim.

Eine weitere korrosionsverhindernde Maßnahme ergibt sich daraus, daß der Druckgasbehälter aus Kunststoff besteht. Dies hat den Vorteil, daß auf ein ansonsten mit einem Schutzlack beschichteten Metalldruckgasbehälter oder auf einen Glasdruckbehälter verzichtet werden kann. Another measure to prevent corrosion arises from the fact that the compressed gas container is made of plastic. This has the advantage that on an otherwise with a protective varnish coated metal pressure gas container or on a Glass pressure vessel can be dispensed with.

Die Erfindung wird anhand eines Ausführungsbeispieles näher erläutert.The invention is illustrated by an embodiment explained.

In der Figur 1 ist ein Ventil 1 für einen Druckgasbehälter 2 mit einem einer Behältermündung 3 angeordneten Befestigungskragen 4, und einem Behältermündungsrand 5 mit einer Dichtung 6 dargestellt. Das Ventil 1 weist ein Ventilgehäuse 7 und einen aus Kunststoff bestehenden federbelasteten Abgabestutzen 8 mit einem Austrittskanal 9 auf. Das Ventilgehäuse 7 besteht aus Kunststoff und ist einteilig mit einem Flansch 10 versehen, der vom Befestigungskragen 4 aufgenommen ist zum flüssigkeits- und druckgasdichten Aufliegen auf den Behältermündungsrand 5. Das Ventil 1 ist nach Art eines Kolbenschiebers vorgesehen, wobei der Abgabestutzen 8 im unteren Endbereich 12 mit mindestens einem Querkanal 13, 13.1 versehen ist. Der Abgabestutzen 8 ist von einem Zylinderteil 14 (Schlauchteil) aus Elastomer umschlossen, der eine nach oben hin als eine Druckfeder wirkende Verlängerung 11 aufweist.1 shows a valve 1 for a compressed gas container 2 arranged with a container mouth 3 Attachment collar 4, and a container mouth rim 5 with a seal 6 shown. The valve 1 has one Valve housing 7 and an existing plastic spring-loaded delivery nozzle 8 with an outlet channel 9 on. The valve housing 7 is made of plastic and is provided in one piece with a flange 10 which from Mounting collar 4 is added to the liquid and pressurized gas-tight resting on the edge of the container mouth 5. Das Valve 1 is provided in the manner of a spool, whereby the discharge nozzle 8 in the lower end region 12 with at least a transverse channel 13, 13.1 is provided. The dispensing nozzle 8 is of a cylinder part 14 (hose part) made of elastomer enclosed one upward as a compression spring acting extension 11.

Das aus einem Elastomer bestehende Zylinderteil 14 weist besonders gute Dichteigenschaften auf (Toleranzausgleich). Das hier dargestellte Dosierventil 1 ist für ein kopfstehendes Applizieren von beispielsweise Schaum vorgesehen. Für ein kopfaufstehendes Applizieren ist das Ventilgehäuse 7 lediglich mit einer nicht dargestellten Steigrohraufnahme und einem dazu angepaßten Steigrohr zu versehenThe cylinder part 14 consisting of an elastomer has particularly good sealing properties (tolerance compensation). The metering valve 1 shown here is for a Upside down application of foam, for example intended. This is for an upright application Valve housing 7 with only one, not shown Riser pipe holder and a riser pipe adapted to it Mistake

Der Abgabestutzen 8 ist mit einer oberen Hubbegrenzung mit dem Befestigungskragen 4 kraftschlüssig verbunden. Wie gestrichelt angedeutet, kann zur unteren Hubbegrenzung ein unterer Anschlag 17 vorgesehen werden. The delivery nozzle 8 is with an upper stroke limit the fastening collar 4 non-positively connected. How indicated by dashed lines, can be used to limit the lower stroke lower stop 17 are provided.
