Description
• Es sind bereits Einlaufventile für Abtrittspülkasten bekannt, bei denen der Wassereinlauf durch einen nach hinten das Ventilgehäuse dicht abschließenden und mit dem Schwimmer des Spülkastens in Verbindung stehenden Kolben gesperrt wird, sobald der Wasserspiegel in dem Spülkasten die gewünschte Höhe erreicht hat und das vordere Ende des Kolbens gegen die Abdichtfläche des Wassereinlaufs drückt, ίο Da der Kolben jedoch das Kolbengehäuse nach hinten dicht abschließen und so mithin schließend geführt werden muß, ist es erforderlich, daß der Kolben und die Abdichtfläche des Wassereinlaufs genau aufeinander gearbeitet sein müssen, andernfalls eine gute Abdichtung mit der vorderen Fläche des Kolbens nicht erzielt wird.• Inlet valves for waste cisterns are already known in which the water inlet by means of a valve housing that tightly seals the valve housing towards the rear and the float the piston connected to the cistern is locked as soon as the water level is in the cistern has reached the desired height and the front end of the piston against the sealing surface of the water inlet presses, ίο Since the piston, however, the piston housing after must be sealed tightly at the back and therefore must be guided to close, it is necessary to that the piston and the sealing surface of the water inlet must be worked precisely on one another otherwise a good seal with the front surface of the piston will not be achieved will.
Die Erfindung besteht nun darin, daß beiThe invention consists in that at
einem solchen Einlaufventil zwischen dem Kolben des Schwimmers und der Abdichtfläche des Wassereinlaufs ein besonderer Körper zum Sperren des Wassereinlaufs angebracht ist, der durch den Kolben gegen die Abdichtfläche des Wassereinlaufs gedrückt wird und hierbei sich so einstellen kann, daß er unabhängig von dem Kolben dichtschließend gegen die Abdichtfläche des Wassereinlaufs zu stehen kommt.such an inlet valve between the piston of the float and the sealing surface the water inlet a special body is attached to block the water inlet, the is pressed by the piston against the sealing surface of the water inlet and thereby itself can be adjusted so that it closes tightly against the sealing surface independently of the piston the water inlet comes to a standstill.
In der Zeichnung ist das Einlaufventil in Fig. I in Ansicht und in Fig. 2 im Schnitt gezeichnet. In the drawing, the inlet valve is shown in FIG. I in view and in FIG. 2 in section.
In das Ventilgehäuse α ist ein Gewindekörper b eingeschraubt, durch den das Ventil an der Wandung des Abtrittspülkastens mittels aufgeschraubter Gegenmuttern befestigt wird. An dem aus dem Abtrittspülkasten vorstehenden Ende des Gewindekörpers b wird die Wasserzuleitung angeschlossen. Im Innern des Ventilkörpers α trägt der Gewindekörper 5 eine Dichtungsscheibe c, welche gegen die Kopffläche des in der Führung ä eines Kolbens e lose eingesetzten Körpers h gerichtet ist. Der Kolben e ist nach hinten aus dem Ventilgehäuse α dicht abschließend herausgeführt und steht hier gegen einen Doppelhebel f, der an einem Arm den Hebel g des Schwimmers des Abtrittspülkastens trägt. Zwischen dem Kolben 0 und der Dichtungsscheibe c des Gewindekörpers b ist in der Führung d ein besonderer Körper h angebracht, der zum Sperren des Wassereinlaufs i dient. Sobald der Wasserspiegel in dem Spülkasten die gewünschte Höhe erreicht hat, drückt der Doppelhebel f durch die Wirkung des Schwimmers gegen das hintere Ende des Kolbens e, wodurch dieser den Körper h gegen die Dichtungsscheibe c des Wassereinlaufs i drückt und diesen sperrt. Hierbei stellt sich der Körper h unabhängig von dem Kolben e stets so ein, daß er mit seiner Abdichtfläche dichtschließend gegen die Abdichtfläche c des Wassereinlaufs i zu stehen kommt. Wird der Abtrittspülkasten geleert, so fällt der Doppelhebel f in die durch strichpunktierte Linien von Fig. 2 gezeichnete Stellung zurück, wonach der Wasserdruck der Zuleitung des Ventils den Körper h und den Kolben e zurückdrückt und das Wasser durch Öffnungen k der Führung ä in den Auslauf I des Ventils eintreten kann.A threaded body b is screwed into the valve housing α , through which the valve is fastened to the wall of the waste cistern by means of screwed-on counter nuts. The water supply line is connected to the end of the threaded body b protruding from the cistern. Inside the valve body α , the threaded body 5 carries a sealing washer c which is directed against the head surface of the body h inserted loosely in the guide ä of a piston e. The piston e is led out tightly to the rear from the valve housing α and stands here against a double lever f , which carries the lever g of the float of the cistern on one arm. Between the piston 0 and the sealing washer c of the threaded body b , a special body h is attached in the guide d , which is used to block the water inlet i . As soon as the water level in the cistern has reached the desired height, the double lever f presses against the rear end of the piston e through the action of the float, whereby the latter presses the body h against the sealing washer c of the water inlet i and blocks it. Here, the body h always adjusts itself independently of the piston e so that its sealing surface comes to rest tightly against the sealing surface c of the water inlet i . If the cistern is emptied, the double lever f falls back into the position shown by dash-dotted lines in FIG. 2, after which the water pressure of the supply line of the valve pushes back the body h and the piston e and the water through openings k of the guide ä into the outlet I of the valve can occur.
