Definitions

  • the invention relates to a glow plug according to the preamble of claim 1.
  • the known glow plugs there are heating and measuring filaments arranged in series, one behind the other usually the heating coil in the front area of the glow plug is arranged, which with a control coil Inner pole of the glow plug is connected.
  • the rule spiral exists here made of a material that is positive or a negative temperature coefficient of resistance has, so that thereby a self-regulation of the glow current for the heating element, whereby the overheating of the Heating element should be avoided.
  • the control behavior of the control element is additional for heating by the current flowing through the Heat radiation from the heating element connected in series affected.
  • This heat transfer from the heating coil to Control coil over the wire connection of the two elements or about the spiral environment requires a certain amount Time and is non-uniform from the direction of the heating coil. This has a delayed and uneven influence the control behavior of the control coil, which can cause the heating coil to melt.
  • the object of the invention is to provide a glow plug to make the control coil more uniform and more quickly influenced by the temperature of the heating coil and is thus regulated and with the control coil as a measuring coil is designed to control the glow current supply.
  • the glow tube 8 in its front area in the Diameter can be tapered.
  • a turn 7.1 of the Inner pole 7 is a block winding 3.2 of a heating coil 3 for example by welding or crimping with the Inner pole 7 electrically connected in an elongated Area 3.1 of the heating coil 3 merges, the stretched Area 3.1 as thermal decoupling between the inner pole 7 and the actual heating coil 3 with a larger coil diameter is used; the heating coil 3 with a large diameter, through which the heating coil turns in close proximity to the Wall of the glow tube 8 are arranged with a Control coil 2, which is known as a measuring coil can act, connected by the weld 5 while the measuring coil 2 via a further weld 5 with the Heating coil 1 connected in the tip region of the glow tube 8 is.
  • the turn 7.1 of the inner pole 7 is preferably with a circumferential channel in which the last connection-side Block winding 3.2 is stored.
  • the heating coil is in turn on the contact pin 6 in the Tip of the glow tube 8 fixed.
  • the contact pin 6 has here a length stop 6.1 and serves in the axial Direction as a boundary, which creates a defined length for welding e.g. TIG welding results, with additional when laser welding the shoulder (6.1) a bullet prevented.
  • Heating coils 1 and 3 are preferred, as follows are also referred to as heating coil sections 1 and 3, with regard to their helix geometry (number and diameter of Wire and turns) in the area of the welds 5 essentially equally designed to ensure the same heat transfer on both sides to ensure in the control coil 2.
  • preferred Materials for the heating coil sections 1 and 3 are CrA1255 (Kanthal) heating conductor material wires used; basically any other heating conductor material is also suitable, that its resistance value depending on the temperature changed little or not.
  • the material of the control coil 2 has positive or negative temperature coefficient of resistance and exists for example from Ni 99.9 or CoFe, where CoFe is one has a higher control factor than Ni 99.9 and thus one better measuring signal when using the control coil as a measuring coil leads; any other material is also suitable, which changes its resistance value over temperature.
  • the rest that corresponds to Figure 1 is for further thermal Decoupling of the heating / control area a reduction in diameter 7.3 of the approach and inner pole 7 provided; being in a hole 7.2 of the approach the connection end of Heating coil section 3.2 is fixed.
  • Contacting with the glow tube tip is made directly, i.e. without contact piece 6 according to FIG. 1.
  • FIG. 3 Another glow plug according to the invention is shown in FIG. 3, in which a heating coil 1 and a control coil 2 in series switched and welded together in 5, with this embodiment a substantial range of length the control coil 2 in the heating coil 1 larger coil diameter is inserted; as an essential area of length the measuring coil 2 is considered such an area that is large enough to be absorbed by the incoming heat surrounding heating coil 1 with regard to its control behavior defined to be influenced.
  • the control coil area that creates the connection to the inner pole 7 2.1 is for the thermal decoupling of the control / heating area and inner pole formed as an elongated helix.
  • the Contact is made directly with the glow tube tip without contact piece 6 according to FIG. 1.
  • FIG. 4 shows a solution in which also a heating coil section 1, a control coil 2 and a heating coil section 3 are connected in series, wherein however, all three coils are pushed into each other, if necessary isolated from each other by insulating tubes 11 and 11.1. Otherwise, the reference numerals have the previously given Importance.
  • FIG. 5 corresponds to the solution according to the invention insofar as the embodiment of Figure 1, as the heating and Control element also in three parts as heating coil section 1, Control coil 2 and heating section 3 is formed, wherein however, as in the embodiment according to FIG. 3, the control coil 2 is inserted into the heating coil section 1.
  • P refers is the heating coil section 1 in the glow tube tip with the Weld 10 fixed; In addition, the glow tube tip can preferably be used have a reduced area 13.1.
  • the Inner pole 7 is opposite the glow tube 8 by an 0-ring 12 sealed. Between the inner pole 7 and body 14 is one annular body seal 15 is provided, between Housing 14 and connecting sleeve 17 with glow plug connection 18th an insulating washer 16 is arranged.
