Abstract

Es wird eine Stabzündspule einer Zündanlage einer Brennkraftmaschine, insbesondere einer Kraftfahrzeugbrennkraftmaschine, vorgeschlagen, umfassend eine auf einem Primärspulenkörper angeordnete Primärwicklung, eine auf einem Sekundärspulenkörper angeordnete Sekundärwicklung sowie eine Kernbaugruppe (10), die ein stabförmiges Blechpaket (12) aus einem ferromagnetischen Material, eine an einer Stirnseite des Blechpakets (12) angeordnete Abdeckung (14), einen aus einem elastischen Material gebildeten, an der anderen Stirnseite des Blechpakets (12) angeordneten Puffer (16) und eine Umhüllung (18) aus Kunststoff umfasst. Erfmdungsgemäß ist der aus dem elastischen Material gefertigte Puffer (16) mit zumindest einem Luftdurchlass (22) ausgebildet ist (Figur 1).
