Description
Falirradpumpe. Gegenstand der Erfindung ist eine weitere Ausbildung der durch das hauptpatent ge schützten Erfindung, mittelst welcher bezweckt wird, schädliche Rückwirkungen von durch das Pumpen erzeugtem Überdruck auf die Pumpe oder den Gummieinsatz zu verhindern, wozu der Gummieinsatz einen zum Druck ausgleich dienenden verjüngten Teil aufweist.
Der Erfindungsgegenstand ist in der Zeich nung in einer Ausführungsform in einem Längsschnitt dargestellt.
In dem zum Pumpenkörper 1 schräg ge stellten Ansatz 2 ist ein mit einem Wulst 3, einer Längsbohrung 4 mit Abstufungen 5 und 6 versehener (Arummieinsatz 7 vorgesehen. Der Gummieinsatz 7 weist einen verjüngten Teil 8 auf.
Bei Benützung der Pumpe wird nach Entfernen des Staubdeckels des an der Rad felge 9 befestigten Luftventils 10 (die Felge und das Luftventil sind in der Zeichnung strichpunktiert dargestellt) der Ansatz 2 so über das Luftventil 10 gesteckt, dass Wulst 3 auf der Felge 9 aufsitzt.
Der verjüngte Teil 8 bewirkt, dass falls ein Luftventil aus diesem oder jenem Grunde nicht arbeiten sollte, oder dass dessen Durch gangsquerschnitt der Pumpenleistung gegen über zu klein sein sollte, eine schädliche Rückwirkung auf die Pumpe oder deren Gummieinsatz verhindert wird, indem der durch das Pumpen hervorgerufene Überdruck nur eine Ausdehnung der Längsbohrung 4. im verjüngten Teile 8 bewirkt.
Falirradpump. The invention is a further embodiment of the invention protected by the main patent ge, by means of which the purpose is to prevent harmful repercussions of overpressure generated by the pumping on the pump or the rubber insert, for which purpose the rubber insert has a tapered part serving to compensate for pressure.
The subject of the invention is shown in the drawing voltage in one embodiment in a longitudinal section.
In the extension 2, which is inclined to the pump body 1, an arm insert 7 is provided with a bead 3, a longitudinal bore 4 with gradations 5 and 6. The rubber insert 7 has a tapered part 8.
When using the pump, after removing the dust cover of the air valve 10 attached to the wheel rim 9 (the rim and the air valve are shown in phantom in the drawing), the approach 2 is placed over the air valve 10 so that the bead 3 rests on the rim 9.
The tapered part 8 has the effect that if an air valve should not work for one reason or another, or that its passage cross-section should be too small compared to the pump output, a harmful reaction to the pump or its rubber insert is prevented by pumping The overpressure caused only causes an expansion of the longitudinal bore 4 in the tapered part 8.
