Description

Paten τ-An Spruch:Godfather τ-An saying:

Sicherheitseinrichtung für schlagwettersichere Motoren, dadurch gekennzeichnet,, daß sie durch den bei einer Explosion hervorgerufenen größeren Druck oder die höhere Temperatur eine Auslösevorrichtung beeinflußt, die den Motor auf direkte oder indirekte Weise abschaltet.Safety device for firedamp proof engines, characterized by, that it is a triggering device due to the higher pressure or higher temperature caused by an explosion that switches off the engine in a direct or indirect manner.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die Versuche mit schlagwettersicheren, ventilierten Motoren haben ergeben, daß bei einer allfälligen Explosion im Innern des Motors so lange ein Nachzünden zu befürchten ist, als sich der Motor in Drehung befindet. Es ist dies darauf zurückzuführen, daß durch den Ventilator dem Motor beständig Frischluft zugeführt wird, welche sich an den glimmenden Rückständen immer wieder von neuemThe tests with flameproof, ventilated engines have shown that in one possible explosion inside the engine as long as there is a risk of reignition as the motor is rotating. This is due to the fact that the The motor is constantly supplied with fresh air, which is attached to the smoldering fan Residues over and over again ίο entzündet.ίο inflamed. Wiederholt sich dieser Vorgang mehrere Male, so wird schließlich nicht nur die Wicklung vollständig zerstört, sondern es kann, was noch schlimmer ist, eine Entzündung der Außengase stattfinden.If this process is repeated several times, not only the winding will end up completely destroyed but it can, what is worse, inflammation of the Outside gases take place. Dieser Übelstand läßt sich vermeiden, wenn man den Motor mit einer Sicherheitsvorrichtung ausrüstet, welche den Strom unterbricht, sobald eine Explosion stattgefunden hat.This inconvenience can be avoided if the engine is fitted with a safety device that interrupts the current as soon as an explosion has occurred. Als auslösende Kraft kann entweder der durch die Explosion hervorgerufene Druck oder auch die höhere Temperatur benutzt werden. Für beide Fälle stehen eine Reihe von bekannten Vorrichtungen zur Verfügung, welche sich für diesen Zweck eignen und deren Konstruktion als nebensächlich übergangen werden kann. Je nach der Anordnung des Schalters wird man den letzteren entweder direkt mechanisch betätigen oder durch die Sicherheitsvorrichtung ein Relais zum Spielen bringen, das den Schalter indirekt auslöst und dadurch ein Abstellen des Motors bewirkt.Either the pressure caused by the explosion can be used as the triggering force or the higher temperature can be used. There is a row for both cases of known devices available which are suitable for this purpose and the construction of which can be ignored as irrelevant. Depending on the arrangement of the switch, the latter will either be actuated mechanically directly or through the safety device a relay to play, which triggers the switch indirectly and thereby deactivates the Engine causes.
