  • Coil 15 is further extended at its upper part by a ring 18, channeled in accordance with 19 and comprising a port 20.
  • a plate 21, made of ferromagnetic material and shaped as a circle, is housed within ring 18; the diameter of said plate 21 being slightly shorter than the internal diameter of ring 18, these two elements can move with respect to each other without any difficulty.
  • Plate 21 comprises, on the one hand, a catch 22 which is engaged in port 20, and, on the other hand, a rod 23 which passes into notch 19 abuts onto a support which is particularly integral with cap 8 (FIG. 2); rod 23 is in turn extended beyond its bearing point on cap 8 by a projection 24 comprising two blades 24a and 24b which come into contact, through their edge, with the lateral surfaces of tubes 4a and 4b respectively. These blades are separated by a slot 25 in which the end portion of rod 9 takes up position and whose cross-sectional dimensions are larger than the width of slot 26, thus making it possible for the projection of plate 21 to lift said rod 9 and thus act on the needle.
  • a sharp pointed metal rod 26 is also fastened onto bridge 5, the point of said rod 26 being located opposite and at a short distance from the end portion of burner 12.
  • Rod 26 is connected by a metal wire 27 to one of the terminals 28 of the second coil winding.
  • a vibrator now shown in the figure, is positioned underneath bridge this vibrator comprises a flexible strip 29 positioned above plate 21.
  • Strip 29 comprises at its end portion, a permanent magnet 30, which has a tendency to adhere against plate 21.
  • a spring rod 31 maintained by lugs 32 is positioned against the internal face of the base plate.
  • This spring rod comprises a cambering constituting a catch which cooperates with a groove and a hole provided in pushrod 16, as will be exposed hereinbelow in FIG. 3.
  • lugs 32 act as a hinge for the cover common to both openings giving access to tubes 4a and 4b, the spring rod acting, in this case, so as to maintain said cover in a closed position in cooperation with a catch provided onto said cover and which said spring rod maintains in an adequate housing.
  • FIG. 2 shows in detail cap 8 comprising a reinforcing edge 33, the gas discharge tube and axial duct 34 within which is housed rod 9 controlling the needle.
  • duct 34, and surrounding rod 9, are positioned a spiral spring acting by compression when rod 9 moves in the direction of arrow 35 and whose role is, when rod 9 is subjected to no other external force, to restore said rod in the direction opposite arrow 35, until it provides complete closure ofthe needle with which it cooperates.
  • Cap 8 is also topped by two catches 36a and 36b parallel to the axis of rod 9 and joined with each other through a wall 37.
  • FIG. 2 shows also a part of the extension of plate 21 and indicates how this extension abuts on wall 37 and is held in place due to two openings 38a and 38b, in which the end portions of catches 36a and 36b respectively slip in; it can be thus seen that ridge 39 of wall 37 determines a horizontal axis around which plate 21 moves.
  • FIG. 3 shows the pushrod 16 extending from coil at its upper part.
  • said pushrod 16 comprises a longitudinal groove 40, over its entire length and a hole 41.
  • spring rod 31, held in abutment against base plate 1 through lugs 32 comprises a cambering 42 which is inserted either in groove 40 or in hole 41 depending on the orientation imparted to rod 16, and it can be seen also that the pushrod ends with knob 43 whose diameter is larger than the diameter of said pushrod.
  • pushrod 16 can be rotated around its axis, either in the direction of arrow 44 or in the opposite direction.
  • cambering 42 of spring rod 31 penetrates into hole 41 and prevents rod 16 from moving in the direction of arrow 45; as a result, coil 15 (FIG. 1) is blocked and cannot move along its axis; this blocking corresponds to the extreme position of the coil towards the top of the lighter.
  • FIG. 4 shows as a cross section, the upper end portion of gas reservoir 7 (FIG. 1) in place within cap 8.
  • the part of reservoir 7, which can be seen in the FIG., comprises a lateral cylindrical surface 46 provided at its end portion with an external threading 47 screwing into the internal threading 48 provided in cap 8.
