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.

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 concerns a heating rod comprising an external sheath (58), a distal heating coil (59) having a thinned distal end portion shaped so as to extend in a closed distal end (72) of the external sheath, an electrically insulating distal core (61) having a thinned distal tip (74) inserted into said thinned distal end of said distal heating coil, characterized in that said thinned distal tip has a peripheral outer surface trace, in any axial plane, having at least one distally thinning continuously curved concave portion having a radially outward oriented concavity.

The invention relates to a dual-mass flywheel comprising: - a first mass (21), - a second mass (22), - a damping device (43) comprising: ∘ a spring device rotationally coupled to the second mass (22) and having at least one surface, named bearing surface (48), facing a lip (24) of the first mass (21), ∘ a roller (45) for each bearing surface (48) of the spring device adapted to roll along the bearing surface (48) associated with this roller (45),
characterised in that the lip (24) comprises, for each roller (45), a surface, named cam surface (46), adapted to allow the roller (45) associated with this cam surface (46) to roll along this cam surface (46) so as to radially compress the spring device upon angular displacement of the first mass (21) with respect to the second mass (22).

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).
摘要:
The invention concerns a heating rod comprising an external sheath (58), at least one heating wire (59, 60), a core (61) and an internal sleeve (63). It also concerns a method for manufacturing a heating rod in which an internal sleeve (63) is inserted between the external sheath (58) and at least one heating wire (59, 60). The internal sleeve (63) has an electrically insulating role and increases the thermal conductivity of the heating rod.
