Abstract (en)

The glow-plug has a glow tube embedded on the combustion chamber side in a metallic tubular housing and filled with insulating powder. In the housing is an electrical connector, projecting into the tube. A ceramic disc working as an insulating seal closes the tube at the end remote from the combustion chamber. The connection between the glow tube (10) and the disc (13) as well as between the connector (12) and the disc results from friction-welding. The connector has two parts of different diameters, one part inside the tube and one part outside it, the latter having the smaller diameter. Thus the connector has a shoulder against which the disc seals.
