Description

ölschalter besitzen ineist oben eine Öffnung, um die sich beim Ausschalten bildenden Gase entweichen zu lassen. Da das öl durch die Entzündung der Gase umherspritzt, tritt S Ölverlust auf und Verschmutzung der Umgegend, was besonders bei beschränktem Raum unangenehm ist.oil switches usually have an opening at the top, to allow the gases that form when switching off to escape. Since the oil is through the ignition of the gases splashes around, S oil loss occurs and pollution of the surrounding area, which is particularly uncomfortable when space is limited.

Man hat diese Übelstände durch Ventile oder Klappen zu beseitigen versucht, die sichAttempts have been made to eliminate these inconveniences by means of valves that are located

Bei solchen Ausführungen liegt jedoch die Gefahr nahe, daß die Ventile oder Klappen verschmutzen und sich dann nicht mehr selbsttätig öffnen, so daß die Gase nicht mehr entweichen können. Die Nachteile, die sich hieraus ergeben, werden nach der Erfin-
ίο closed when the switch was opened due to the gas pressure and then opened the ram under the action of a spring to allow the gases to escape.
In such designs, however, there is a risk that the valves or flaps will become dirty and then no longer open automatically, so that the gases can no longer escape. The disadvantages that result from this, according to the invention

Die Zeichnung zeigt ein Ausführungsbeispiel. Entzünden sich beim öffnen des Schalters Gase, so wird durch den Gasdruck der The drawing shows an embodiment. If gases ignite when the switch is opened, the gas pressure causes the

*5 Ventilteller b, der am Gehäuse α angebracht ist, nach oben gegen seinen Sitz Z gepreßt und dadurch das Ventil geschlossen. Sobald sich die Gase innerhalb des ölgefäßes verteilt haben, öffnet sich 'das Ventil unter dem Einfluß der Feder c, und die Gase können entweichen. Damit das Ventil nicht aus irgendeinem Grunde hängenbleibt und die öffnung geschlossen hält, wird- dies zwangläufig durch einen Nocken und eine Hebelanordnung e bis k, die auch im Innern des ölechaltergehäuses angeordnet sein kann, geöffnet. Der auf der Schaltwelle/ sitzende Nockeng hebt am Ende der Ausschaltbewegung mittels des Ansatzes; k die Stange i hoch und öffnet durch den um e drehbaren Hebel d das Ventil.* 5 valve disk b, which is attached to the housing α, is pressed up against its seat Z, thereby closing the valve. As soon as the gases have distributed within the oil compartment, the valve opens under the influence of the spring c and the gases can escape. So that the valve does not get stuck for any reason and keeps the opening closed, this is inevitably opened by a cam and a lever arrangement e to k, which can also be arranged in the interior of the oil switch housing. The cam g , which is seated on the switching shaft /, lifts at the end of the switch-off movement by means of the projection; k up the rod i and opens the valve with the lever d, which can be rotated about e.

Patent-Anspruch:Patent claim: Entlüftungsventil für ölschalter, welches durch den bei Explosionen auftretenden Gasdruck' die Entlüftungsöffnung schließt, dadurch gekennzeichnet, daß das Ventil mit der Schaltwelle des ölschalter derart verbunden ist, daß es in Abhängigkeit von der Stellung der Schaltwelle zwangläufig wieder geöffnet wird.Vent valve for oil switch, which is caused by the Gas pressure 'closes the vent opening, characterized in that the valve with the switching shaft of the oil switch is connected in such a way that it depends on the position of the selector shaft inevitably opens again.
