Definitions

  • the invention relates to a glow plug for self-igniting internal combustion engines.
  • the known glow plugs consist essentially of one
  • Candle housing a connection device for the glow current, a tube fastened to the candle housing, which is closed at its end facing away from the candle housing, and a wire-coil-shaped resistance element embedded in heat-conducting insulating powder, which is arranged in the part of the tube protruding from the candle housing and serving as a glow pencil.
  • the candle housings of the various commercially available glow plugs differ depending on the design and construction of the engine in which the glow plug is to be installed, in their length, which determines the overall length of the glow plug candles. A large variety of different long candle housings and connection devices for contacting the heating element are therefore required for production.
  • the glow plug according to the invention has the advantage that different by the use of variable spacers Overall lengths of the glow plug can be realized without having to manufacture different length candle housings or to have connecting bolts of different lengths available.
  • the necessary product range of the individual parts that are necessary for the assembly of a glow plug candle is significantly reduced, which ultimately leads to a reduction in the cost of the glow plug due to the possible production in larger numbers.
  • the housing and the connecting bolt can be made in two parts, which are always made the same regardless of the final length, and can then only be adapted to the desired length by the variable adapter.
  • connection between the individual components can be made by welding, soldering, shrinking or pressing. Ultimately, it is advantageous to have the end faces of the sections of the candle housing and the variable
  • FIG. 1 shows the basic structure of a glow plug
  • FIG. 3 shows a possibility of connecting the intermediate piece to the housing according to FIG. 2
  • FIG. 4 shows a glow plug with variable connection contact. Description of the embodiments
  • the glow plug shown in Figure 1 consists of a candle housing 11 with a thread 12 and a hexagon
  • the housing 11 is traversed by an axial bore, a glow plug 14 being fastened at one end to the combustion chamber end of the housing 11.
  • the other end 15 of the glow plug 14 protruding into the combustion chamber is closed.
  • the glow plug 14 is made of a temperature-resistant material.
  • the connecting element 18 is fastened in the candle housing 11 and forms a threaded bolt 19 on the side of the housing 11 remote from the combustion chamber, to which the glow current is connected.
  • An insulating washer 20 prevents electrical contact between the housing 11 and the connecting element 18.
  • Figure 2 shows a candle housing in a sectional view, for the sake of simplicity only one side is drawn starting from the axis of symmetry. The same parts are provided with the same reference numerals as in Figure 1. In the arrangement according to the invention that is
  • Candle housing 11 from two parts, a first part 21, which holds the glow plug 14 sealingly.
  • the second rear part 22 carries the walking winch 12 for screwing the glow plug into the cylinder and the hexagon 13. Both parts 21 and 22 are connected to one another by an intermediate piece 23.
  • This intermediate piece 23 is connected to the first and the second part, for example by welding, soldering, shrinking or pressing.
  • the intermediate piece 23 can be used in a wide variety of lengths. The length of the intermediate piece 23 is in each case
  • FIG. 3 shows a further possibility of how the connection between the individual parts 21 or 22 of the housing 11 and the intermediate piece 23 can take place. It is advantageous to provide the connecting surfaces with a shoulder 24, since this results in a much better fixation of the individual parts to be connected.
  • FIG. 4 also shows a possibility of adapting the internal arrangement of the glow plug, consisting of glow plug 14, connecting element 18 and threaded bolt 19 to different lengths. So the glow plug 14 and the attached connecting pin 18 are pre-assembled in length. Depending on the overall length of the candle housing, the corresponding variable threaded bolt is then used with the Contacting to the connecting element 18 used.
  • the connection 25 from connecting bolts to threaded bolts can be made by means of shrinking, soldering or friction welding. The use of a standard glow pencil with connection element makes production more cost-effective.

Abstract

L'invention concerne une bougie-crayon de préchauffage destinée à être placée dans la chambre de combustion d'un moteur à combustion interne à compression de l'air, comprenant un culot, un élément de connexion pour l'arrivée du courant d'incandescence et un tube fixé au culot, ledit tube étant fermé à son extrémité opposée au culot. Dans la partie du tube faisant saillie dans le culot et servant de tige incandescente, se trouve une spirale de fil incorporée dans un matériau isolant. Le culot (11) est produit en deux parties et, selon la longueur souhaitée pour la bougie-crayon, on utilise une pièce intermédiaire (23), dont on peut choisir la longueur, qui relie l'une à l'autre une première partie (21) et une seconde partie (22) du culot (11).
