Definitions

  • the invention relates to a lamp, in particular a paraffin lamp, with a shell-like container, in which a non-flammable wick is arranged in the center, which is held in a riser, receives heat of fusion through the fuel filled in the container and the melt flows to the wick.

  • An absorbent body surrounding the wick is provided within the tube which is used to draw in the liquefied fuel, e.g. Wax, serves.
  • the tube surrounding the wick prevents the flame from dropping as the fuel level drops.
  • the tube cannot prevent the wick from burning with the candle, which is why the wick is not recyclable.
  • the object of the invention is to disclose a luminaire, the flame of which does not drop as the fuel level falls, and which enables effortless ignition even when the wick and solidified wax are burnt out.
  • the object is achieved in that the riser consists of thin-walled metal and touches the wick, which protrudes on the flame side, touching all sides while leaving a narrow inflow gap.
  • the design of the rising body made of thin-walled metal quickly heats the wax solidified in the casing and liquefies it.
  • the metal riser and a surrounding sheath conduct the combustion heat quickly and directly into the fuel, e.g. Wax, keep going. Molten wax is fed into the wick through the narrow inflow gap in a capillary fashion.

Abstract

L'invention concerne une lampe fonctionnant avec de la paraffine (1) qui comprend un récipient (2) en forme d'écuelle dans lequel se trouve une mèche (3) incombustible. La mèche (3) est maintenue dans un corps vertical (4) qu'entoure une enveloppe (5) incombustible cylindrique ou de type cylindrique perméable à la matière combustible (W) fusible. Le récipient (2) contient une matière combustible (W) en fusion qui peut être acheminée jusqu'à la mèche (3) à travers le corps vertical (4). Le corps vertical (4) est en métal à paroi mince et entoure la mèche (3) en étant en contact de tout côté avec elle, avec une fine fente d'alimentation (F1) entre. Le corps vertical (4) métallique chauffe très vite la matière combustible (W) qui fond de ce fait rapidement. La mèche (3) est ainsi imprégnée en continu de matière combustible (W).
