| 摘要 |
<p>The invention concerns a glow plug comprising a heating rod (11), a plug body (13), a mounting device (48) for mounting the heating rod, permitting axial translation movements of the heating rod relative to the plug body and ensuring impermeability between the heating rod and the plug body, and a load sensor (17) which is interposed in said proximal zone between the heating rod and the plug body. The plug body is composed of multiple distinct metal tubes (45, 95) which are rigidly assembled and extend each other axially, comprising, around said mounting device and the load sensor, a metal distal tube (45) extending a metal proximal tube (95), said distal tube having a lesser thickness than that of said proximal tube.</p> |
