  • connection / distribution section is dimensioned in such a way that it completely penetrates the porous evaporator medium.
  • the port / distribution section be sized is that it completely penetrates the porous evaporator medium.
  • the following invention further relates to a line connection element for a A fuel vaporization device comprising a port allocation section, which for insertion into a porous evaporator medium and for connecting a fuel line is formed and a distribution opening arrangement and a termination area which terminates the connection / distribution section at an end region and protruding outward beyond it.
  • a fuel evaporation arrangement is general denoted by 10.
  • This fuel evaporation assembly 10 includes a plate-like ausgestaltetes porous evaporator medium, for example designed as a mesh, knitted fabric, foamy material or like.
  • This porous evaporator medium generally has the property that in this initiated liquid fuel or hydrocarbon due to the porosity under capillary action in the volume range distributed and then at an appropriate temperature at one of Fuel vapor receiving chamber facing side 14 to be positioned this evaporative evaporator medium 12 can evaporate.
  • One of this Side 14 facing away from the rear 16 can be covered with a cover 18 be to a fuel vapor outlet at this back to 16 prevent.
  • this Opening 20 is a Line connection element 22 used.
  • the line connection element 22 has for this purpose a tube-like connection / distribution section 24, whose outer dimension is dimensioned so that it approximately the inner dimension of the opening 20 corresponds to or slightly larger is such that the connection / distribution section 24 under at least low pressure in the porous evaporator medium 12 is maintained.
  • the connection / distribution section 24 is dimensioned to be porous Evaporating medium 12 completely and preferably also the cover 18 or configured therein opening 26 passes through and still protruding beyond this cover 18.
  • connection / distribution section 24 Through a plate-like end portion 28 is the connection / distribution section 24 completed.
  • line connection element 22 When inserted into the opening 20 line connection element 22 thus covers the plate-like end portion 28th on the one hand, the opening 20 and further adjacent to the opening 20 or these surrounding and forming region 30 of the porous evaporator medium 12.
  • the plate-like end portion 28, as well as the connection / distribution section 24 be designed with a substantially circular outer contour.
  • a distribution port arrangement 32 designed in the terminal / distribution section 24 is further a distribution port arrangement 32 designed.
  • a tubular or hose-like designed fuel line 38 is with her End portion 40 inserted into the connection / distribution section 24.
  • the line 38 and the section 24 may be in coordination with each other so be dimensioned that the line 38 in press fit and thus firmly in Section 24 is held.
  • the provision of a Screw connection between the section 24 and the conduit 40 is possible.
  • an elastically erformbarer Pulsation damper 44 may be provided.
  • This compressible under pressure Pulsation damper 44 for example, provided by Elastomer material, catches pressure peaks by increasing the volume of the Volume range that can be occupied by the fuel on and thus ensures a further homogenization of the fuel flow.
  • the embodiment or positioning of the openings 34 has an advantageous Influence on the fuel distribution.
  • These openings 34 are preferably positioned such that the fuel in the porous evaporator medium 12 either up or to the side or in one Intermediate area takes place.
  • a direct fuel outlet down, so in that direction in which gravity acts is not possible, so that also the capillary influencing influence or this superimposed Gravity influence can be compensated.
  • a possible for this alternative embodiment is shown in Fig. 3.
  • the distribution port assembly includes 32, a single opening 34 'extending over an angular range of 180 ° in the tube wall 36 extends and the fuel delivery essentially only upwards or to the side, but not after below, ie in the direction of gravity, allows.
  • the line connection element 22 also the effect that the introduced into the porous evaporator medium 12 Fuel 12 must first flow through the area 30 thereof, ie in a larger volume and thus larger surface area The page 14 must be distributed before ever taking it to him Chamber can get.
  • Another through the use of Line connection element 22 effect achieved is that especially in use in a burner, ie one under comparatively high temperatures working system, the volume range in which the Fuel introduction takes place through the plate-like end portion 28th covered and thus isolated. Excessive warming in the area of Fuel introduction, which the risk of early boiling of the Fuel brings with it, can thus be reduced.
  • the plate-like end portion 28 by a Insulating element 46 to be covered, which shown in Fig. 1 as a cap member is and provides an isolation gap 48 to the plate-like end portion 28.
  • the dimensioning of the various components or system areas is to choose so that the desired effects achieved as efficiently as possible become. So the risk of too early fuel evaporation can thereby be counteracted that in particular for the line connection element 22 thermally insulating materials are used.
  • An uneven, induced by too early fuel vaporization, Pulsation-like fuel introduction into the porous evaporator medium 12th can also be counteracted by the fact that the total opening cross section the distribution opening arrangement 32 is dimensioned so that Although the desired amount of fuel can still flow, however Such a throttling effect is obtained, which always sufficient and the pressure in the volume range which counteracts premature evaporation 42 generated.
  • Fig. 4 is the use of a fuel evaporation arrangement according to the invention 10 in conjunction with a chamber housing 50, for example Burning or mixing chamber housing, shown.
  • a chamber housing 50 for example Burning or mixing chamber housing
  • This case is in Essentially pot-shaped with a peripheral wall 52 and a thus, for example, integrally configured bottom wall 54.
  • this housing 50 is thus a fuel receiving chamber 56 configured in which the on the side 14 of the porous evaporator medium 12 leaking fuel is then taken up.
  • This can with Air or other mixed materials are mixed through openings 58 can flow from radially outside into the chamber.
  • the air introduced through the openings 58 then in the air Chamber 56 are mixed with the fuel vapor and, for example ignited by a dashed line indicated ignition member 60 and for combustion to be brought.
  • a configured for example as a heating coil or heating coil heater 62 is present at the from porous evaporator medium side facing away from the cover 12th .
  • a heating coil or heating coil heater 62 is present at the from porous evaporator medium side facing away from the cover 12th .
  • an insulating layer 64 with respect the bottom wall 54 isolated so that the heat provided there in the Essentially completely for heating the porous evaporator medium 12 or the liquid fuel contained therein can be used, thus further supporting the fuel evaporation.
  • connection / distribution section 24 in FIG its lower portion is slightly thicker to one in the form of an opening 64th to provide a designed holding arrangement.
  • this opening 64 can a another functional element, e.g. a temperature sensor 66, used and be held in it. This also penetrates corresponding openings in the insulation 64 and the bottom wall 54, thus the temperature to be sensed directly in that volume region of the chamber 56, in which also the fuel vapor enters this chamber 56.
  • a temperature sensor 66 e.g. a temperature sensor 66
  • connection / distribution section 24 configured rotationally symmetrical with respect to its center axis can be and thus be configured the same thickness in all peripheral areas can, for example, a plurality of such openings 64 via his Scope distributed to be able to provide.

  • the porous evaporator medium 12 There is in the over the tubular connection / distribution section 24 lying area the porous evaporator medium 12 a small distance between the Outer circumference of the portion 24 and the porous evaporator medium 12th educated. In this way a direct contact is avoided there and the heat transfer further difficult. Furthermore, this gap contribute to the further homogenization of the fuel distribution, wherein, for example, it may be provided that such a distance only in the gravity-direction upper portion of the section 24 is present is, while in the lower area in which in Fig. 2, for example no openings 34 are provided, then again a direct contact can be present.
