Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device on a burner for controlling the outlet of fuel to be atomized from an outlet nozzle opening into a burner chamber when the burner is shut down which has a compressed air filled with the outlet nozzle connected via a line a diaphragm limited chamber, has a spring acting on the diaphragm in the sense of increasing the volume of the chamber and an actuator acting on the diaphragm in the sense of reducing the volume of the chamber with increasing compressed air flow to the burner.
  • the actuator is formed by a slide valve, which is coupled to the diaphragm and has axial nozzle openings which conically narrow in the direction of flow and serves as an outlet nozzle, in a compressed air channel which blocks fuel feeds which open into the compressed air channel if the compressed air flow fails.
  • the object of the invention is to provide a device according to the preamble of claim 1, which automatically ensures in the event of failure or switching off the oscillating burner that no active ingredient escapes from the nozzle with certainty.
  • the slide 2 of a slide valve 4 lies in a line 6, 8 leading to an oscillating combustion chamber, which is also not shown, under an active substance reservoir, not shown.
  • the line 6 is connected on the input side to the active substance storage container.
  • the line 8 ends in a nozzle 10 which is adjacent to the oscillating combustion chamber.
  • the slide 2 is to be adjusted by a membrane 12.
  • the membrane 12 adjoins a space 14 which has an air inlet opening 16 through which air with a pressure dependent on the strength of the air intake flow of the oscillating burner, a small airflow 18 also flows out, and a second opening which can be opened by a manually actuatable actuator 20 and outlet opening 22 to be closed.
  • the actuator 20 is provided with a screw body 24 which can be turned by means of a knurled handle 26. By unscrewing the screw body 24, the opening 22 is closed, as a result of which the pressure in the space 14 rises, the membrane 12 pushes the slide 2 downward and the slide valve 4 thus comes into the open position.
  • the space 28 below the membrane 12 communicates with the atmosphere via openings 30.
  • a spring 32 tries to push the slide body 2 against the pressure in the space 14 upwards in order to bring the slide body 2 into the closed position.
  • the slide 2 passes through a second membrane 34, to which it is attached with a flange 36.
  • the slide 2 is hollow inside. Active ingredient to be flowed through the line 6 can flow through the constriction 38 and the ring distribution space 42 into the interior of the slide 2 when the openings 40 in the slide 2 are at the level of the ring distribution space 42.
  • the active ingredient then flows through a space 44 below the membrane 34 before it reaches the line 8.
  • the slide 2 reaches the closed position, it takes the membrane 34 upwards and the volume of the space 44 increases, causing active ingredient to flow out the line 8 is sucked back.
  • the space 46 above the membrane 34 is in constant communication with the atmosphere via an opening 48.
  • FIG. 2 is essentially constructed like that according to FIG. 1, so that only the different elements have to be described.
  • a displaceable bolt 50 is provided which connects the two membranes 12, 34.
  • the line 6 leading from the active substance container into the space 46 above the membrane 34 has been omitted.
  • the line 8 opens into a line 52 which leads to the nozzle 10.
  • the line 52 is connected on the input side to the active substance container via a tap.
