Abstract

Gegenstand der vorliegenden Erfindung ist ein Anzündsystem für Detonatoren oder pyrotechnische Verzögerungselemente. Das System enthält zusätzlich zu den bekannten Anzünd- und Zündelementen (2, 4) eine zwischen Zündquelle (2) und Anzündsatz (4) bzw. Verzögerungssatz angeordnete Scheibe (3) aus porösem anorganischem Material. Diese Scheibe (3) bewirkt einen verbesserten Anbrand und gleichmäßigeren Abbrand der Anzünd- und Verzögerungssätze (4, 5) in diesen an sich bekannten Anzündsystemen. The present invention relates to an ignition system for detonators or pyrotechnic delay elements. The system contains in addition to the known ones Ignition and ignition elements (2, 4) between ignition source (2) and ignition block (4) or delay block (3) made of porous inorganic material. This disc (3) causes an improved burn and more even burn the ignition and delay rates (4, 5) in these known ignition systems.
