Description

Verschluß für Flüssigkeitskühler von Kraftfahrzeugen und ähnliche Behälter Die Erfindung befaßt sich mit einer besonciers vorteilhaften Ausgestaltung eines Verschlusses für Flüssigkeitskühler von Kraftfahrzeugen und ähnliche Behälter. Es ist bekannt, solche Verschlüsse mit einem Überdruckventil und einem Unterdruckventil für den Behälter zu vereinigen und dabei solche federbelasteten Ventile ineinander anzuordnen.Closure for liquid coolers of motor vehicles and the like Container The invention is concerned with a particularly advantageous embodiment a closure for liquid coolers of motor vehicles and similar containers. It is known to have such closures with a pressure relief valve and a vacuum valve to unite for the container and thereby interlocking such spring-loaded valves to arrange.

Nach der Erfindung wird ein solcher Verschluß dadurch besonders günstig gestaltet, daß beide Ventile von einem sie durchdringenden und in dem Verschlußdeckel befestigten Stift so gehalten werden, daß sie beim Abnehmen des Deckels vom Stiftkopf getragen «-erden, der als Hubbegrenzung für® das Unterventil dient.According to the invention, such a closure is particularly favorable designed that both valves from a penetrating them and in the closure cap attached pin are held so that they are when removing the cover from the pin head worn «-ground, which serves as a stroke limiter for the lower valve.

Hierdurch ist ein einfacher und besonders zweckmäßiger Verschluß geschaffen, der allen Betriebsbedingungen genügt. Der Verschluß mit den Ventilen kann als Ganzes leicht, ohne Beschädigungen zu erleiden, herausgenommen werden. Seine Ausgestaltung macht weitgehendste Verwendung von Preßstoff als Baustoff möglich.This creates a simple and particularly useful closure, which satisfies all operating conditions. The closure with the valves can be used as a whole can be easily removed without being damaged. Its design makes the widest possible use of compressed material as a building material.

In der Zeichnung ist ein Ausführun-sbeispiel im Schnitt dargestellt.An exemplary embodiment is shown in section in the drawing.

Die Behälterwand i trägt den Befestigungsring 2, auf welchem durch Schrauben 3 das Gehäuse 4 befestigt ist. Dieses hat bei 5 einen Abflußansatz, an den ein Rohr oder Schlauch 6 anschließen kann. Mit dem Versehlußdeckel io ist ein nach innen ragenderStift ii verbunden. Um diesen lagern sich das Überdruckventil 13 mit Sitz i4 und das darin angeordnete Unterdruckventil 20 mit Sitz 21, der an einem nach innen vorgestülpten Teil 16 des Überdruckventils 13 vorgesehen ist.The container wall i carries the fastening ring 2, on which the housing 4 is fastened by screws 3. This has a drain attachment at 5 to which a pipe or hose 6 can connect. An inwardly projecting pin ii is connected to the closure lid io. The overpressure valve 13 with seat i4 and the underpressure valve 20 with seat 21 arranged therein, which is provided on a part 16 of the overpressure valve 13 that is turned inward, are located around this.

Die Feder 15 für das Überdruckventil stützt sich einerseits gegen die Unterseite des Verschlußdeckel.s und andererseits gegen den Boden des ausgestülpten Teils 16 ab. An dem letzteren liegt nun wiederum das eine Ende der Feder -22 für das Unterdruckventil -2o an, deren anderes Ende gegen den Federteller 24 am oberen Ende des Hohlschaftes 23 des Unterdruckventils 20 drückt. Zur Begrenzung des Hubes dieses Ventils dient der Stiftkopf des Stiftes i i, der von einer Abdeckung 12 umschlossen sein kann. Die Ausstülpung 16 des Überdruckventils 13 ist an ihrem Umfange mit Rillen 17 versehen. durch welche bei geöffnetem Ventil 13 Flüssigkeit oder Dampf austreten und über den Ansatz ; und Rohr 6 entweichen kann. Umgekehrt kann bei geöffnetem Unterdruckventil 20 Luft von oben her in den Behälter eintreten.The spring 15 for the pressure relief valve is supported on the one hand against the underside of the closure lid.s and on the other hand against the bottom of the everted Part 16 from. One end of the spring -22 for is now in turn on the latter the vacuum valve -2o, the other end against the spring plate 24 at the top The end of the hollow shaft 23 of the vacuum valve 20 presses. To limit the stroke this valve is used by the pin head of the pin i i, which is enclosed by a cover 12 can be. The protuberance 16 of the pressure relief valve 13 is grooved on its circumference 17 provided. through which liquid or vapor emerge when the valve 13 is open and about the approach; and pipe 6 can escape. Conversely, when the Vacuum valve 20 air enter the container from above.

Beide Ventile sind in einfachster Weise durch den Stift ii am Gehäusedeckel io gehalten. Wird dieser abgenommen, so trägt der Stiftkopf die beiden Ventile. Nach Wegnahme der Umkleidung 12 des Stiftkopfes können die Ventile auf einfache Weise durch Herausschrauben des Stiftes i i aus dein Deckel io ausgebaut und ebenso wieder eingesetzt werden.Both valves are in the simplest possible way through the pin ii on the housing cover kept io. If this is removed, the pin head carries the two valves. After removing the casing 12 of the pin head, the valves can be opened in a simple manner Way by unscrewing the pin i i removed from your lid io and likewise to be reinstated.
