Definitions
- the invention relates to a glow plug for self-igniting internal combustion engines.
- a glow plug for self-igniting internal combustion engines.
- DE-A-1363 8164 known glow plug consist essentially of a candle case, one Connection device for the glow current, an am Tube attached to the candle housing attached to its from End facing away from the candle housing is closed and one in thermally conductive insulating powder embedded wire helical resistance element, which in the protruding from the candle housing, serving as a glow plug Part of the tube is arranged.
- a spark plug is used Arrangement in the combustion chamber described in the candle housing Connection element and one fastened in the candle housing Isolator has.
- the candle case is in two pieces Made out.
- the glow plug according to the invention has the advantage that Use variable spacers different Overall lengths of the glow plug can be realized without that different length candle housings are made or connecting bolts of different lengths must be available.
- the necessary product range of the individual parts for the Assembling a glow plug will be necessary significantly reduced what is ultimately due to the possible Manufacture in larger series of one
- the glow plugs become cheaper.
- the housing and also the connecting bolt can be in two parts, which are independent of the final length are always made the same, be produced and then only by the variable Intermediate piece can be adapted to the desired overall length.
- FIG. 1 shows the basic structure of a Glow plug
- Figure 2 with a glow plug housing
- Intermediate piece for realizing variable lengths
- Figure 3 a possibility of connecting the intermediate piece with the Housing according to Figure 2 and Figure 4 with a glow plug variable connection.
- the glow plug shown in Figure 1 consists of a Candle housing 11 with a thread 12 and a hexagon 13.
- the housing 11 is traversed by an axial bore, a at the combustion chamber end of the housing 11 Glow plug 14 is attached at one end.
- the other End 15 of the glow plug 14 projecting into the combustion chamber locked.
- the glow plug 14 consists of a temperature resistant material. Inside the glow plug there is insulating ceramic powder 16, and one Wire coil arrangement, which serves as a heating element, the Wire coil arrangement 17 from a heating coil with constant Resistance and a control coil with temperature-dependent There is resistance.
- the connecting element 18 is in the candle housing 11 attached and forms on the far side of the combustion chamber Housing 11 a threaded bolt 19 on which the The glow current is connected.
- An insulating washer 20 prevents electrical contact between the housing 11 and the connecting element 18th
- Figure 2 shows a candle housing in section Representation, for simplicity only one side of the axis of symmetry is drawn starting from. Parts right away are here with the same reference numerals as in FIG. 1 Mistake.
- a first part 21 which holds the glow plug 14 sealingly.
- the second rear Part 22 carries the walking winch 12 for screwing in the Glow plug in the cylinder and the hexagon 13.
- Both Parts 21 and 22 are interconnected by an intermediate piece 23 connected.
- This intermediate piece 23 is the first and the second part, for example by welding, soldering,shrinking or pressing connected.
- the intermediate piece 23 can can be used in different lengths.
- the Length of the intermediate piece 23 is in each case Depends on the required length of the glow plug certainly. This has the advantage that the first and second Section 21 and 22 of the housing 11 in each case the same Geometry and be made with the same dimensions can.
- Figure 3 shows another way how the connection between the individual parts 21 or 22 of the housing 11 and the intermediate piece 23 can be done. So it is beneficial the connecting surfaces each with a paragraph 24 to provided, as a much better fixation of the individual parts to be connected.
- Figure 4 also shows a possibility, the inner Arrangement of the glow plug, consisting of glow plug 14, Connection element 18 and threaded bolt 19 to various Adapt overall lengths. So are the glow plug 14 and the one on it attached connecting bolts 18 in their length pre-assembled. Then depending on the length of the candle housing the corresponding variable threaded bolt with the Contacting to the connecting element 18 used.
- the Connection 25 from connecting bolts to threaded bolts can by means of shrinking, soldering or friction welding. By the use of a standard glow pencil with connection element manufacturing becomes cheaper.
