KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Befestigung des Isolierkörpers im Zündkerzenkörper erfolgt nach der Erfindung in der Weise, daß zwischen dem konischen, sich nach außen verjüngenden Bund a des Isolierkörpers (Fig. i) und dem als Hohlzylinder ausgebildeten Ende b des Kerzenkörrpers ein entsprechend geformter Ring c aus geeignetem Material fest eingepreßt wird, worauf man das überstehende Ende von b ίο durch Börteln oder Pressen umlegt, wie bei d der Fig. 2 gezeigt.The fixing of the insulator in the spark plug body is carried out according to the invention in such a way that between the conical, outwardly tapering collar a of the insulator (Fig. I) and the form of a hollow cylinder end b of the Kerzenkö r rpers a correspondingly shaped ring c of suitable Material is firmly pressed in, whereupon the protruding end of b ίο is turned over by flanging or pressing, as shown at d of FIG.
Zweckmäßigerweise wird der genannte Konus bei α so steil angenommen, daß eine • kräftige Keilwirkung zwischen den Teilen a und c entsteht, ebenso ist es zweckmäßig, daß der Ring c streng in den Zylinder b paßt, da alsdann der Isolierkörper durch Vermittlung des Ringes c schon vollständig fest im Kerzenkörper gehalten wird, bevor die Umbörtelung oder Umpressung stattgefunden hat.Appropriately, the said cone at α is assumed to be so steep that a strong wedge effect arises between parts a and c , and it is also expedient that ring c fits tightly into cylinder b , since then the insulating body is already through the intermediary of ring c is held completely firmly in the candle body before the flanging or pressing has taken place.
Dem Ring c fällt die Aufgabe zu:
I. den Isolierkörper genau zentrisch im Kerzenkörper zu halten,Ring c has the task:
I. to keep the insulator exactly centered in the plug body,
2. die Abdichtung der Kerze gegen Gasdruck zu bewirken,2. to seal the candle against gas pressure,
3. den Isolierkörper gegen Beschädigung zu schützen, indem dieser Ring den beim Umbörteln oder -pressen entstehenden Druck aufnimmt.3. to protect the insulator against damage by putting this ring into the Umbörteln or -pressing absorbs the pressure.
Es darf nach diesem das Material des Ringes c weder zu hart noch zu weich sein, da einerseits die Abdichtung gegen Gasdruck ein sattes Anschmiegen der Flächen erfordert, während andererseits für eine genaue Zentrierung, sowie für ausreichenden Schutz beim Umbörteln eine genügende Widerstandsfähigkeit vorhanden sein muß.According to this, the material of the ring c must neither be too hard nor too soft, since on the one hand the sealing against gas pressure requires a snug fit of the surfaces, while on the other hand there must be sufficient resistance for precise centering and adequate protection when beading.
Kupfer, geglühtes Messing oder sehr weiches Eisen sind nach diesem als besonders geeignete Materialien zu betrachten, wenn auch die Verwendung anderer Stoffe nicht ausgeschlossen erscheint.Copper, annealed brass or very soft iron are considered special after this to consider suitable materials, even if the use of other substances is not appears excluded.
Um dem Isolierkörper weiteren Schutz gegen Beschädigung zu bieten, kann zweckmäßigerweise ein zweiter Dichtungsring e (Fig. 3) zur Anwendung gelangen, welcher die in achsialer Richtung auftretende Pressung zwischen Isolierkörper und Kerzenkörper vermittelt. .In order to offer the insulating body further protection against damage, a second sealing ring e (FIG. 3) can expediently be used, which mediates the pressure occurring in the axial direction between the insulating body and the plug body. .
Die Vorteile der nach der Erfindung hergestellten Zündkerze liegen in einer wesentlichen Vereinfachung ■ und Verbilligung der letzteren, neben einer gerade infolge dieser Vereinfachung erzielten Verminderung möglicher Fehlerquellen, während andererseits gleiche Güte der Zentrierung und Abdichtung gewährleistet ist, wie bei Zündkerzen von komplizierterer Bauart.The advantages of the spark plug produced according to the invention lie in an essential one Simplification and ■ cheaper the latter, in addition to one precisely as a result of this Simplification achieved reduction of possible sources of error, while on the other hand the same quality of centering and sealing is guaranteed as with spark plugs from more complicated design.
