Glow plug i.e. metallic glow plug, for heating medium e.g. air, surrounding glow plug, has contact pin, glow filament and pipe positioned against each other by stops and centerings and mechanically/electrically connected with each other

摘要

The plug has a contact pin, a glow filament and a glow pipe exactly positioned against each other by stops and centerings and mechanically and electrically connected with each other. The contact pin and a rear part of the glow filament are coaxially and axially positioned such that a pole pin is adapted to inside diameters of the rear part of the glow filament. The contact pin and the rear part of the glow filament are axially positioned such that the contact pin is pushed until stopping an inward hitting passage at the rear part of the glow filament.
