Abstract (en)
[origin: WO2010003727A1] A glow tube is proposed, particularly for a sheathed-type glow plug. The glow tube, which has a dome-shaped closed end section (27) and a cylindrical open end section (28), is composed of at least two glow tube parts disposed behind one another in the axial direction. The one glow tube part is produced at the closed end section (27) by a seamless glow tube cap (31), and the other glow tube part is produced at the open end section (28) by a substantially cylindrical glow tube extension (32).
