Description

Zündkerze. Gegenstand vorliegender Erfindung ist eine Neuerung, die sich auf Zündkerzen für Explosionsmotoren bezieht. Bekanntlich ist der isolierende Teil dieser Zündkerzen sehr zerbrechlich und bietet nur wenig Widerstand gegen mechanische Einflüsse sowie Schwankungen der Temperatur. In den meisten Fällen besteht der Körper aus Porzellan, Steingut, Speckstein oder aus einer Zusammensetzung dieser Materialien mit anderen keramischen Bestandteilen. Es ist daher, selbst wenn die größte Sorgfalt in der Herstellung dieser Zündkerzen beobachtet wird, eine schwer lösbare Aufgabe, diese so widerstandsfähig herzustellen, daß sie für eine längere Betriebsdauer gebraucht werden können.Spark plug. The present invention is an innovation that refers to spark plugs for explosion engines. It is well known that it is insulating Part of this spark plug is very fragile and offers little resistance to mechanical Influences and fluctuations in temperature. For the most part, the body exists made of porcelain, earthenware, soapstone or a combination of these materials with other ceramic components. It is, therefore, even with the greatest care is observed in the manufacture of these spark plugs, a difficult task, to make them so resistant that they are needed for a longer period of operation can be.

Diesen Übelstand zu beseitigen, ist Zweck vorliegender Enfindung, welche darin besteht, dem Material der Zündkerzen Oxyde oder metallische Salze in einem Verhältnis wie z bis ro Prozent und noch mehr, entsprechend dem jeweiligen Bedürfnisfall, zuzusetzen. Dadurch wird erreicht, daß, ohne die Isolierungseigenschaft der Zündkerzen wesentlieh herabzumindern, eine ganz erhebliche Widerstandskraft gegenüber mechanischen Kräften und Temperaturschwankungen verliehen wird. Es hat sich dabei herausgestellt, daß die Oxyde oder Salze des Eisens, Mangans und besonders Salze des Kobalts, Kupfers und Zinks die geeignetsten sind, um den erstrebten Zweck zu eireichen.The purpose of the present invention is to remedy this problem, which consists in the material of the spark plugs in oxides or metallic salts a ratio such as z to ro percent and even more, depending on the respective If necessary to add. This achieves that without the insulating property to reduce the spark plugs substantially, a very considerable resistance against mechanical forces and temperature fluctuations is conferred. It has it turned out that the oxides or salts of iron, manganese and especially Salts of cobalt, copper and zinc are the most suitable for the intended purpose to be rich.
