Definitions

  • the invention relates to an oscillating burner according to the preamble of claim 1.
  • the fuel / air ratio which enters the combustion chamber when starting is dependent on the type of actuation of the starting air pump. In addition, this ratio is dependent on the level of the fuel in the fuel tank. The same applies to an oscillating burner known from FR-PS 1374195.
  • the object of the invention is to make the fuel-air ratio when starting independent of the type of actuation of the starting air pump and the level in the fuel tank.
  • the solution to this problem is specified in the characterizing part of claim 1.
  • the amount of fuel that enters the combustion chamber through the nozzle is, when using the invention, dependent on the amount of displacement of the wall and this amount in turn depends on the amount of compressed air supplied by the starting air pump.
  • the fuel-air ratio is evened out when starting.
  • Even when the burner is running, the amount of fuel supplied is largely independent of the fuel level in the fuel tank.
  • the valve can be opened in the last phase of starting, which is also useful for making the above-mentioned quantitative ratio more uniform when starting.
  • an embodiment according to claim 2 is preferably provided.
  • the oscillating burner according to the exemplary embodiment has a combustion chamber 2, to which a nozzle 4 leads for the periodic intake of liquid fuel.
  • the outlet cross section of this nozzle 4 can be adjusted by means of an adjusting screw 6.
  • the nozzle 4 is connected via a line 10 containing a check valve 8 to a fuel tank 12 which may be filled to the level 14 with liquid fuel.
  • a start-up air pump 18, which can be actuated by hand in the direction of the arrow 16, generates an air stream which sweeps over the nozzle 4 and is directed toward the combustion chamber 2.
  • the line 10 is guided through a chamber 20, the volume of which can be reduced by moving a membrane or wall 22 by means of compressed air supplied by the starting air pump 18 via a line 24.
  • valve 28 In the chamber 20 there is a valve 28 to be opened by the fuel flowing from the fuel tank 12 against the pressure of a spring 26.
  • the valve 28 is articulated on an arm 30 of an actuator 32 in the form of a two-armed lever, on the other lever arm 34 the Spring 26 attacks.
  • a shoulder 36 abuts the free end of the lever arm 34 on the wall 22 when the membrane 22 has been displaced to a certain extent.
  • the starting air pump 18 feeds a blowing nozzle 40 via a first check valve 38, which is directed into the intake pipe 42 of the combustion chamber 2. Upstream of the nozzle 4 there is a second check valve 44 in the inlet of the intake pipe 42, which can be opened by the air stream emerging from the blow nozzle 40 and also opens during each intake phase of the oscillating burner.
  • the start air pump 18 is connected via a line 46 to the fuel tank 12 above the level 14 of the fuel contained in it.
  • the wall 22 is first displaced by the starting air pump 18, so that fuel is injected into the intake pipe 42 through the opening check valve by means of the nozzle 4 in accordance with this displacement. After a certain displacement, the shoulder 36 abuts the lever arm 34, whereby the valve 28 is opened. The further delivery of fuel to the nozzle 4 then takes place (when starting) by the hydrostatic pressure of the fuel in the fuel tank 12 and the (further) displacement of the membrane 22.
  • the pressure of the spring 26 on the lever arm 34 is to be set so low that the flow of the fuel drawn in by the combustion chamber 2 in the intake phase is not interrupted when the burner is running.
  • the fuel drawn in should therefore always keep valve 28 open due to its fluid force.
  • the line 46 is beneficial, but can be omitted.

Claims (3)

1. Brûleur à oscillations, comprenant une chambre de combustion (2) vers laquelle, en vue d'une aspiration périodique de combustible liquide, est dirigée une buse (4) disposée dans un tube d'aspiration (42) et raccordée à un réservoir (12) de combustible par l'intermédiaire d'un conduit (10) renfermant un clapet antiretour (8), ainsi qu'une pompe à air de démarrage (18) au moyen de laquelle un courant d'air, balayant la buse (4) et dirigé vers la chambre de combustion (2), peut être engendré en vue de la mise en route, caractérisé par le fait que le conduit (10) traverse une chambre (20) dont le volume doit être diminué, par le déplacement d'une cloison (22), grâce à de l'air comprimé délivré par la pompe à air de démarrage (18); par le fait que le conduit (10) renferme, entre la chambre (20) et le réservoir (12) de combustible, une soupape (28) devant être ouverte à l'encontre de la pression d'un ressort (26) par le combustible provenant dudit réservoir (12) de combustible; et par le fait que la soupape (28) présente un organe de manoeuvre (32) avec lequel la cloison mobile (22) vient en prise, après une course de déplacement prédéterminée, en vue d'ouvrir ladite soupape (28).
2. Brûleur à oscillations selon la revendication 1, caractérisé par le fait que la pompe à air de démarrage (18) alimente, par l'intermédiaire d'un premier clapet antiretour (38), une buse d'insufflation (40) dirigée vers le tube d'aspiration (42); et par le fait qu'un second ctapetantiretour (44) se trouve dans le conduit d'aspiration (42), en amont de la buse (4).
3. Brûleur à oscillations selon la revendication 1 ou 2, caractérisé par le fait que la pompe à air de démarrage (18) est raccordée par l'intermédiaire d'un conduit (46) au réservoir (12) de combustible, au-dessus du niveau (14) du combustible contenu dans ce réservoir.
