Definitions

  • the invention relates to an oscillating burner according to the preamble of claim 1.
  • the starting air pump In the case of such oscillating burners, the starting air pump is usually operated by hand.
  • the fuel-air ratio that enters the combustion chamber when starting is therefore dependent on the type of actuation of the starting air pump. This quantity ratio also depends on the level of the fuel in the fuel tank.
  • 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 set out in the characterizing part of claim 1.
  • the amount of fuel that enters the combustion chamber through the nozzle is dependent on the degree of displacement of the wall when the invention is applied, and this amount in turn depends on the amount of compressed air supplied by the starting air pump. As a result, the fuel-air ratio is evened out when starting.
  • an embodiment according to claim 2 is preferably provided.
  • the opening of the valve according to claim 2 can also take place in the last phase of starting, which in turn is useful for making the quantitative ratio more uniform when starting.
  • the training according to claim 3 is provided.
  • an embodiment according to claim 4 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.
  • the line 10 is led through a chamber 20, the volume of which can be reduced by moving a membrane 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 a two-armed lever 32, on the other arm 34 the spring 26 engages.
  • a shoulder 36 At the free end of the arm 34, a shoulder 36 abuts the membrane 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 flow 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 diaphragm 22 When the oscillating burner is started, the diaphragm 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. 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 the valve 28 open due to its flow force.
  • the line 46 is beneficial, but can be omitted.
