Abstract

Es wird eine Glühstiftkerze mit einem Gehäuse (11) vorgeschlagen, in dessen Längsbohrung (12) ein Glühstift (13) festgelegt ist. Der Glühstift (13) weist ein an seinem brennraumseitigen Ende (15) verschlossenes Glührohr (14) auf, in dessen Innenraum sich ein in axialer Richtung erstreckendes, in ein Isoliermaterial (18) eingebettetes Widerstandselement (17) als Heizeinrichtung befindet. Das Widerstandselement (17) weist mindestens eine Verbindungsstelle (30) auf, die eine Schmelzsicherung für den elektrischen Stromkreis ausbildet. Die Verbindungsstelle (30) ist aus einem schmelzfähigen Material (33) ausgeführt, wobei die Schmelztemperatur des schmelzfähigen Materials (33) unterhalb der Schmelztemperatur des Materials des Glührohrs (14) liegt.

It is proposed a glow plug with a housing (11), in the longitudinal bore (12) a glow plug (13) is fixed. The glow plug (13) has a glow tube (14) closed at its combustion chamber end (15), in the interior of which there is a resistance element (17), which extends in the axial direction and is embedded in an insulating material (18), as a heating device. The resistance element (17) has at least one connection point (30), which forms a fuse for the electrical circuit. The joint (30) is made of a meltable material (33), wherein the melting temperature of the meltable material (33) is below the melting temperature of the material of the glow tube (14).
