Definitions

the invention relates to a device on a vibrating burner for controlling the exit of active substance to be atomized from an outlet nozzle opening in a vibrating burner chamber when the vibrating burner is stopped.
the object of the invention is to provide a device of this type which automatically ensures when the oscillating burner fails or is switched off that no active substance escapes from the nozzle with certainty.
the device is characterized by a valve arrangement which can be adjusted by the intake air flow of the oscillating burner against spring force and which, in the event of failure of the intake air flow under the spring force, generates an active ingredient sucking back suction from the nozzle in a line leading to the oscillating combustion chamber.
a separate line can be provided with a valve that can be adjusted by hand, for example, for feeding the active substance into the oscillating combustion chamber.
a preferred embodiment of the invention is characterized in that the line in which the suction is generated in the event of failure of the intake air flow is at the same time the line through which the active substance is introduced into the oscillating combustion chamber.
the device is characterized in that the line via the valve arrangement is guided from an active substance storage container to an oscillating combustion chamber and is also blocked by the valve arrangement in the event of a failure of the intake air flow.
valve is a slide valve, the slide of which can be adjusted by a membrane, the membrane bordering a space which has an air inlet opening through which the air is subjected to a pressure which depends on the strength of the air intake flow flows in, which has a first always open small outlet opening, through which air flows out, and which has a second outlet opening to be opened and closed by a manually operable actuator.
the membrane In normal operation, the membrane is only under the pressure which arises because of the always open small outlet opening. By opening the second outlet opening by means of the manually operable actuator, this pressure is reduced and the slide valve is thereby brought into its closed position.
the slide is coupled to a second membrane which delimits a space through which the active substance flows downstream of the slide valve. If the slide valve is moved into its closed position, the space mentioned is automatically enlarged as a result, which results in the desired return suction effect.
the slide is preferably biased by a spring in the closed position of the slide valve.
the effective area of the first membrane is preferably larger than that of the second membrane, so that the space mentioned for sucking back the active substance can certainly expand.
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 borders a space 14 which has an air inlet opening 16 through which air flows in at a pressure which is dependent on the strength of the air intake flow of the oscillating burner.
the room has a first always open small outlet opening 18, through which air flows out, and a second outlet opening 22, which can be opened and closed by a manually operable actuator 20 Knurl handle 26 is twisted.
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 upwards against the pressure in the space 14 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 substance 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 substance 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 are to be described.
a displaceable bolt 50 is provided which connects the two membranes 12, 34.
the Lei leading from the active substance container into the space 46 above the membrane 34 tion 6 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.
