1 Claim. (Cl. 12S-145) This invention relates to internal combustion ical. The glow plug is placed in position in the engines and more particularly to devices known following manner: The twisted part of the reas glow plugs for assisting the combustion of sistance wire is inserted into the central hole 1 fuel charges in internal combustion engines. and the conical portion of the @011 e is forced Glow plugs usually include a body which is up against the conical end il oi the plug body. 5
screwed into the cylinder wall, an electrode and Then the plug is screwed into the bore hole lll a projecting coiled resistance wire secured at one by means of the thread 8, thus causing the conend to the electrode and at the other end to the ical portion of the coil 5 to be interposed between body. the conical end 9 and bore hole lil. The tight- 10 The object oi this invention is to increase the ening takes place by ll. i3 is an additional in- 10 strength of the glow plug and to form them in sulation.
