摘要:
The invention relates to a glow plug comprising a heating rod (11), a plug body (13) having a receiving housing (14) for the heating rod, a distal flexible membrane between the heating rod and the plug body, and a load sensor (17). The flexible membrane comprises a flexible collar (26) which extends radially orthogonally relative to the heating rod. A radial extremity portion (58) of said flexible membrane is welded to a fixing ring (15) for fixing to the plug body.
摘要:
The invention relates to a method of manufacturing a glow plug (1) in which a metal distal tube (2) is fitted-on around a heating rod (3) made of ceramic material, a metal proximal tube (4) is rigidly joined, by a distal end (5) of the said proximal tube (4), to a proximal end (6) of the distal tube (2), and the proximal tube (4) is joined to a plug body (7) in such a way that at least one distal portion of the proximal tube (4) projects from a distal end (8) of the plug body.
摘要:
The invention relates to a glow plug comprising a hollow body (7), a proximal rod (6) connected electrically to an external connector (20), a heating rod (3) and a distal rod (2), characterised in that the glow plug comprises an electrically insulating internal sleeve (5) disposed between the conducting rods (2, 6) and the plug body (7), the said sleeve bringing about mechanical and electrical contact between the proximal rod (6) and the distal rod (2) at their joint, and keeping the conducting rods (2, 6) at a distance from the plug body (7).
