Abstract (en)
[origin: WO2009103649A1] A glow tube (14) for a sheathed-type glow plug and a method for the production thereof are proposed. In order to produce the glow tube (14), a seamlessly produced glow tube body (30) having a length L is used, which has a tubular long end section (31) having an outside diameter D and an inside diameter d, a truncated short end section (32) having a reducing diameter Dj and an opening diameter dö, and a reducing section (33) located between them. The reducing section (33) forms a uniform taper of the outside diameter D to the reducing diameter Dj and the inside diameter d to the opening diameter dö. The production of the seamless glow tube body (30) is performed by deep drawing or by extrusion of a compound made of a metal powder or by metal powder spraying.
