Definitions

  • a flame adjusting device of a gas lighter has a disk in the conduit between the fuel tank and the burner valve, which disk is porous and substantially incom- [30] Foreign Application Priority Data Sept. 25, 1968 Luxembourg 56,958 pressibie and is provided with at least one a i body in pressure contact with a major surface of the disk, [52] 11.8. CI. 138/44, 138/46 and the area f contact between the elastic body and [51] int.
  • the invention relates to gas lighters, and relates more particularly to a flame adjusting device for gas lighters.
  • Gas lighters which have a flame adjusting device in the conduit between the tank and the burner which carry out the flame adjusting by means of a capillary reduction, or by compression, of a porous mass, thereby varying the flow cross section of the gas within the burner valve.
  • a porous mass is formed as a compressible disk, to which there is applied an elastic ring, such as a rubber ring.
  • the flame adjusting is carried out by compressing the porous mass and the rubber ring: the larger the compression of the material, the smaller will be the flow cross section, and thus there will be transmitted a correspondingly reduced amount of gas.
  • There arrangements however, have the disadvantage that the adjustment is difficult to reproduce, and does not admit of automatic regulation.
  • this is accomplished by a control by the tank pressure of the pressure exerted from an elastic body against a porous substantially incompressible disk.
  • a control by the tank pressure of the pressure exerted from an elastic body against a porous substantially incompressible disk.
  • Either one or several elastic bodies may be compressed either by the gas pressure within the tank and- /or by the pressure of a set screw.
  • the form of the elastic body is either that of acone, or of a funnel or cup; the elastic body or bodies may have central bores into which there may be placed metal rings.
  • the self-regulation of the flame adjustment may be improved by providing a second porous member on the side of the first porous member which faces in the direction towards the fuel tank.
  • the elastic body may be composed of co-axial O-rings, the diameter of which decreases towards the center.
  • FIG. 1 is a fragmentary central sectional view of a flame adjusting device for gas lighters showing a porous disk and a funnel shaped elastic body applied to one side of the porous disk before any substantial pressure is applied between the elastic body and the disk;
  • FIG. 2 is a sectional view of a detail of FIG. 1, but showing the porous disk and the deformed elastic body owing to pressure exerted between the elastic body and the disk;
  • FIG. 3 is a sectional view showing a detail similar to FIG. I, but disclosing two elastic bodies applied oppositely on the two surfaces of the disk;
  • FIG. 4 is a fragmentary sectional view, similar to FIG. 1, but embodying a modification, showing a conical elastic body pressed by a pressure element against the porous disk;
  • FIG. 5 is a plan view of the pressure element of FIG.
  • FIG. 6 is a large scale fragmentary sectional view, similar to FIG. 1, but embodying a further modification showing a funnel shaped porous disk, and a second porous disk, and a cup shaped elastic body engaging the funnel shaped disk, indicating the position of these parts before the application of any substantial pressure;
  • FIG. 7 is a fragmentary sectional view of a detail of FIG. 6, but showing the funnel shaped disk and the cup shaped elastic body in engagement after the application of pressure;
  • FIG. 8 is a fragmentary sectional view similar to FIG. 1, but embodying a further modification, showing two porous disks, and a funnel shaped elastic body;
  • FIG. 9 is a fragmentary sectional view, similar to FIG. 1, but showing a further modification in which the elastic body is composed of a plurality of co-axial O-rings;
  • FIG. -10 is a fragmentary sectional view, similar to FIG. 1, but showing a still further modification in which a porous disk is surmounted by an elastic body and supported by a resilient rubber body.
  • FIGS. 1 and 2 there is provided a conduit 1 in which there is disposed a connecting piece 2 that leads to a fuel tank (not shown).
  • a burner valve 3 is provided, the lower portion of which is shown in FIG. I projecting into the conduit 1.
  • an elastic body such as a rubber body 4 which is funnel shaped; below the rubber body 4 there is provided a porous, substantially incompressible disk shaped body or member 5.
  • the porous member 5 preferably is porous in the axial direction, namely axially of the conduit 1.
  • the elastic body 4 has a bore 41 that is aligned with a bore 31 that is defined in the lower portion of the burner valve 3.
  • FIG. 3 there are shown two elastic bodies 4, one on each of the major sides of the disk shaped porous member 5.
  • the two bodies 4 perform the same function as that of the single body 4 of FIG. 1.
  • both bodies 4 are funnel shaped, as in FIG. 1.
  • the provision of two elastic bodies 4, instead of but a single body 4 as in FIG. 1 offers the advantage that the cross sectional area for the gas stream flow is now reduced also upstream of the disk 5, as well as downstream thereof. This arrangement is particularly advantageous when the disk 5 is a porous member that is primarily porous in a direction axially of the disk, respectively the conduit 1.
  • FIG. 3 This arrangement of FIG. 3
  • the elastic rubber body 4 is no longer funnel shaped but is cone shaped.
  • the function of the body 4 relative to the porous disk member 5, however, is similar to that of the preceding views.
  • the self regulation is provided for in accordance with the embodiment of FIG. 4, for which purpose there are provided elastic seals 6 below the porous disk member 5.
  • the purpose of the elastic seals 6 is to avoid the bypassing around the disk 5 by the gases that stream upwardly. In the embodiments of FIGS. 1-3, on the other hand, this sealing function is performed automatically by the elastic body or bodies 4.
  • the seal between the conduit housing 1 and the burner valve 3 furthermore includes an additional elastic sealing element 7.
  • the advantage of this arrangement of FIG. 4 is that the expanded gas will pass around the elastic body 4 in contact with the interior surface of the conduit housing 1. This increases the heat exchange between the gas and the conduit 1. This heat exchange prevents a back condensation that might easily lead to flickering of the flame.
  • the lower portion of theburner valve 3, as best shown in FIGS. 4 and 5, is provided with radial ribs 32, to promote the flow of the gas into the burner valve 3.
  • the porous member 5 has an arcuate funnel shaped upper surface 51 for contact with the lower, inner surface of the cup shaped elastic body 4 (FIG. 7).
  • the lower surface 52 of the porous member 5 is similarly arcuately shaped, in order to provide for uniform thickness throughout the width of the porous member 5.
  • the elastic body 4, as previously indicated, is cup shaped and surmounts the porous member 5. Above the elastic body 4 there is again provided a portion. In the preceding views, this portion has been identified as a part of the burner valve 3. In FIGS. 6-10, however, the portion 3 is shown disk shaped; it either forms a part of the burner valve or leads to it; and hence in FIGS. 6-10 it will be referred to as the portion 3.
  • the cup shaped elastic body 4 of FIGS. 6 and 7 has an upper tubular projection 43 that engages the portion 3 for pressure takeup.
  • the elastic body 4 surrounds with its cup shaped portion the porous member 5.
  • a cup shaped porous body 8 is provided that supports the porous member 5 and which, in turn, is supported by helical compression spring 9 that is supported from below.
  • the second porous member namely a porous disk 10 that is porous in the axial direction is mounted on the cup shaped body 8, upstream of the porous member 5.
  • the porous disk 10 together with the porous member 5 provide for a pressure drop between the interior and exterior of the elastic body 4.
  • FIG. 7 there is illustrated in detail as to how the elastic body 4 under pressure will cover a portion of the upper surface 51 of the porous member 5, and thereby will reduce the cross section for the flow of the gas through the porous member 5.
  • FIG. 8 there is shown a further modification wherein the elastic body 4 has a funnel shaped lower portion that surrounds the porous disk member 5 as well as the second porous disk 10.
  • the elastic body 4 has an upper plate portion 44 for engaging the underside of the portion 3.
  • FIGS. 6-10 The portion 3 of FIGS. 6-10 is movable axially, in contrast to the corresponding arrangement of FIGS. 1-5.
  • a helical compression spring between the lower funnel shaped portion of the body 4 and the upper plate portion 44 thereof and which presses the plate portion 44 against the portion 3 and presses the lower funnel shaped portion towards the porous disk member 5.
  • the cup shaped porous body 8 in a manner similar to that of FIG. 6 separates the disks 5 and 10, and the spring 9 exerts pressure between the connecting piece 2 and the disk 10.
  • the elastic body of the previous views isin the form of a series, for instance three O-rings 45, 46, 47 which are co-axial about the axis of the conduit l..
  • the O-rings 45, 46 and 47 engage with their lower surfaces the upper surface of the porous disk member 5.
  • the elastic body has a greater height than width, thereby providing for a greater resiliency in the axial direction.
  • a further elastic body 101 that supports the porous disk member 5 from below and, in turn, is supported from below.
  • the portion 3 engages with its underside the upper surface of the elastic body 4.
  • the lower portion of the elastic body 4, on the other hand, similar to the embodiment shown in FIG. 1, is funnel shaped.
  • a flame adjusting device for use in connection with a gas lighter having a conduit between the fuel tank and the burner valve and an incompressible porous member in said conduit,
  • At least one elastic body operable to engage at least a portion of a surface of said porous member, the area of said portion varying in accordance with the variations of pressure exerted between said elastic body and said surface, thereby adjusting the flow of gas in at least a portion of said conduit, and a second elastic body operable to engage at least a portion of another surface of said porous member.
  • a flame adjusting device as claimed in claim 1, said second elastic body having a shape similar to that of said first body and being arranged substantially symmetrically relative thereto about said porous member.
  • a flame adjusting device for use in connection with a gas lighter having a conduit between the fuel tank and the burner valve and an incompressible porous member in said conduit,
  • At least one elastic body operable to engage at least a portion of a surface of said porous member, the area of said portion varying in accordance with the variations of pressure exerted between said elastic body and said surface, thereby adjusting the flow of gas in at least a portion of said conduit, said elastic body including a plurality of co-axial O-rings having decreasing height with decreasing radius.
