Description
Entlüftungskappe zum Aufsetzen auf den Verschluß eines Kraftstoffbehälters, insbesondere von Kraftfahrzeugen Die Erfindung bezieht sich auf eine Kappe, die den Verschluß eines Kraftstoffbehälters dichtend umhüllt und mit einer Abzugsleitung verbunden ist, die die aus dem Behälter durch den Verschluß entweichenden Gase nach der Fahrzeugaußenseite hin ableitet. Essoll dadurch vermieden werden, daß bei Behälterverschlüssen, die innerhalb des Fahrzeugaufbaus liegen, die Dämpfe in das Innere des Kraftfahrzeuges ziehen können. Es ist bereits eine derartige Kappe bekannt, die jedoch den Nachteil hat, daß sie nicht dicht auf dem Einfüllstutzen sitzt; denn sie besteht aus elastischem Material und kann nur unvollkommen am Behältereinfüllstutzen zur Anlage gebracht werden. Außerdem muß beim Tanken die ganze Kappe abgenommen werden, sobald der Behälterverschluß zugänglich sein soll.Vent cap for placing on the cap of a fuel tank, in particular of motor vehicles The invention relates to a cap which the cap of a fuel tank is sealingly enveloped and with a discharge line is connected to the gases escaping from the container through the closure the outside of the vehicle. It should be avoided that with container closures, which lie within the vehicle body, the vapors into the interior of the vehicle can pull. Such a cap is already known, but has the disadvantage has that it does not sit tightly on the filler neck; because it consists of elastic Material and can only imperfectly be brought into contact with the container filler neck will. In addition, the entire cap must be removed when refueling, as soon as the container closure should be accessible.
Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß eine derartige Entlüftungskappe zweiteilig und aus starrem Material gefertigt ist, wobei der die Abzugsleitung tragende Unterteil am Einfüllstutzen des Kraftstoffbehälters fest angeordnet und der abnehmbare Oberteil mit Hilfe eines Renkverschlusses dichtend darauf aufsetzbar ist. Nach einer weiteren Ausbildung der Erfindung kann der Abzugsstutzen am Grunde des den Einfüllstutzen wannenartig umfassenden Kappenunterteils angebracht sein.This disadvantage is avoided according to the invention in that such The vent cap is in two parts and made of rigid material, with the The lower part carrying the discharge line is fixed to the filler neck of the fuel tank arranged and the removable upper part sealed with the help of a bayonet lock can be placed on it. According to a further embodiment of the invention, the trigger nozzle attached to the base of the lower part of the cap that encompasses the filler neck like a tub be.
Der Vorteil dieser Anordnung besteht darin, daß der Unterteil der Kappe gut dichtend den Einfüllstutzen umfassen kann und nicht mehr entfernt werden muß. Der Oberteil ist zum Tanken leicht abnehmbar und in üblicher Weise gut dichtend wieder aufzusetzen.The advantage of this arrangement is that the lower part of the Cap can encompass the filler neck with a good seal and can no longer be removed got to. The upper part is easily removable for refueling and seals well in the usual way put back on.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen. dargestellt, die einen Schnitt und eine Ansicht der Entlüftungskappe zeigen.An embodiment of the invention is in the drawings. shown, which show a section and a view of the vent cap.
Der Einfüllstutzen a trägt den Unterteil c der Entlüftungskappe, der mit Hilfe einer Dichtung b am Einfüllstutzen anliegt. Der Unterteil ist wannenartig ausgebildet. An seinem Grunde ist das Abzugsrohr d vorgesehen. an das der nach der Fahrzeugaußenseite hin führende Abzugsschlauch od. dgl. angeschlossen ist. Der Unterteil ist nur se weit nach oben gezogen, daß die Behälterverschlußkappe ohne weiteres zu erreichen und abzunehmen ist. Auf den Unterteil c ist der Oberteil e der Entlüftungskappe aufsetzbar. Er enthält einen Dichtungsring f, der in einer Nut untergebracht ist und mit dem oberen Rand des Unterteils in Anlage kommt. Der Oberteil ist mittels eines an sich bekannten Renkverschlusses g, h mit dem Unterteil zu verbinden. Die in der Kappe sich sammelnden Gase können lediglich durch den Abzug d entweichen.The filler neck a carries the lower part c of the vent cap, the rests against the filler neck with the aid of a seal b. The lower part is tub-like educated. At its base, the exhaust pipe d is provided. to the after the The outside of the vehicle leading to the exhaust hose or the like. Is connected. The lower part is only se far up that the container cap is easily can be reached and decreased. On the lower part c is the upper part e of the ventilation cap attachable. It contains a sealing ring f which is housed in a groove and comes into contact with the upper edge of the lower part. The top is by means of a per se known bayonet lock g, h to be connected to the lower part. the Gases that collect in the cap can only escape through the trigger d.
