Definitions

  • the invention relates to a glow plug and a method to their preparation according to the preamble of the patent claims 1 or 5.
  • Such a method and glow plug are from JP 2000-111048 A and EP 0 324 627 A.
  • a constriction in the form of a radial cross-section reduction provided, which causes the heat conduction between Sharing the heating coil or between the actual heating coil and the downstream control coil is reduced.
  • Glow plugs usually have a glow tube, in which a heating coil is arranged, embedded in a ceramic filling is.
  • a heating coil is arranged, embedded in a ceramic filling is.
  • the area is reduced in the so-called feed method, being either continuous cylinder or a linear one Rejuvenation to the heater tip can be achieved.
  • the glow rod is inserted into the rotary hammer tool;
  • the tools have an insertion bevel, wherein through the rotary hammers and the axial feed of the glow tube the diameter is reduced.
  • the object of the invention is, bypassing the known in the prior art disadvantages the compaction in significantly improve the glow tube tip; at the same time a new shape of the glow tube tip area more Possible applications, in particular the possibility of Attach additional components, tap.
  • a conventional glow plug has a glow tube 5 with internal heating coil 4, which in a ceramic filling 3 embedded and the combustion chamber end of the Glow tube 5 is connected thereto by welding 6; at the opposite end of the heating coil 4 with the Terminal pole 1 connected.
  • the front combustion chamber side area 5a of the glow tube 5 is according to the known feed method reduced in a cylindrical shape.
  • Possible starting form is a glow rod according to FIG 2 / 2.1 without additional rejuvenation and without additional compaction the glow stick tip.
  • the pure piercing technique can be combined be carried out with the feed method, wherein the axial feed of the machined workpiece in with Arrow indicated direction takes place.
  • FIG. 4.2 shows a schematic view of an invention deformed glow tube tip on that with a tool produced according to Figure 4.3, the baking of different Length (11, 12, 13), where W1 and W2 the angulation of the front surfaces with respect to the piercing direction specify.
  • FIG. 5 shows a schematic longitudinal section of the combustion chamber side region 5a of a glow tube 5 of another glow plug according to the invention, which has a groove-shaped constriction 12 above the glow tube tip; the Einstechreduzi fürs vide by means of plunge tools 8 with different curved front surfaces 11 different radii R 1 , R 2 and R 3 is shown in Figure 5.1, in which case reference is otherwise made to the description of Figure 3.
