The invention relates to an adjustable burner for gas lighters, with a burner head and an adjusting collar having a socket-shaped screw part in which an adjusting element and a with the fuel tank connected, fixed gas supply channel are arranged coaxially, wherein the Adjusting member, which is moved in the axial direction when adjusting the screw part, from one with one cylindrical head provided shaft.

In general, it has become known in the relevant field to provide more than one gas duct, namely two canals that merge into a common canal (Belgian Patent 516,220). It is also known for adjustable burners to have a nozzle insert to be provided with gas channels, which, however, ends in an insert, the bottom surface of the same with a Sealing washer is provided, which forms a seal when the cap of the lighter is closed causes between the insert and the nozzle element, which is movable in the axial direction and when opening the cap can be lifted up by the gas pressure, so that the gas flows out (Belgian patent 564 351). It has also become known a valve insert in which escaping gas not through the thread turns, but through one or more flattened areas of the thread extension flows, which does not serve as a gas channel (Austrian patent 193 176).

These previously known adjustable burners for gas lighters now have the disadvantage that it is not possible, on the one hand, to achieve a very precise and, on the other hand, a very simple setting, regardless of whether you want to create one flame or two flames of a certain size.

According to the invention it is now possible to overcome these disadvantages, the adjustable burner thereby is characterized in that the shaft of the adjusting member protrudes into the gas supply channel, in which upper area a surrounding the shaft with play and on its head as well as on the bore wall of the screw part tightly fitting sealing ring is arranged.

A further development according to the invention consists in that the cylindrical head of the adjusting member several radially or axially extending in its lower and upper flat surface as well as on its circumference and communicating gas channels known as such.

Another embodiment of the invention is that in the bore of the burner opening a nozzle insert with a press fit is provided, adjustable burner for gas lighters

which consists of at least two twisted ones, extending from the upper edge of the burner opening to the cylindrical one Head of the adjusting member extending wires is formed.

By simply turning the adjustment ring, the gas supply to the burner opening and thus the Flame height can be adjusted. If the valve is only slightly opened, a single flame is formed, the however, when the opening is greater, it depends on the gas pressure and the width of the burner opening splits into two partial flames.

The invention is explained below with reference to the drawings.

F i g. 1 is a vertical section through a burner with an adjustment valve;

F i g. 2A is a vertical section through a burner head;

F i g. Figure 2B is a top plan view of a burner head of Figure 2A;

F i g. 3 is a vertical section through another burner head;

F i g. 3B is a cross section through a burner head according to section AA in FIG. 3 A.

In Fig. 1, a screw part 6, which has an adjusting collar 6 ′ and a burner head 3, is screwed into a threaded bushing T fastened to the lighter housing 7. The screw part 6 is pierced in the longitudinal direction, the upper part 1 of the bore containing a nozzle insert 4 which is formed from two wires wound around one another and between

and the wall of the bore two helical circumferential nozzle channels 1 'leaves free, the Open just below the upper edge of the slightly conically widened burner opening 2. Below the Nozzle insert 4 is followed by a burner valve, which consists of an adjusting member 15 with a cylindrical Head 9 'and a shaft 9, from a socket 8 and fixed in place in the lighter housing 7 from a surrounding the shaft 9 with play and on its head 9 'as well as on the bore of the screw part 6 tight sealing ring 8 'consists. The shaft 9 tapers at its lower end. being cylindrical head 9 'is on its lower and upper flat surfaces as well as on its periphery with several radially or axially extending and interconnected gas channels 9 " Mistake. The socket 8 can also be the neck part of a lighter arranged but not shown Be a pressurized gas cartridge. If the screw part 6 is screwed into the sleeve 7 ', the sealing ring 8 'pressed together until it rests firmly on the shaft 9 in the upper area. Then this is Burner valve closed. Conversely, the valve is opened by unscrewing the screw part 6 and set as a function of the passage cross section of the annular space 10.

In Fi g. 2 A shows how the setting of the gas supply affects the flame formation at nozzle openings 5 of an adjustable burner according to FIG. 1 affects. When the burner valve is slightly open a flame 11, indicated by a dash-dotted line, is formed, which, however, changes with further Opening in two partial flames 12 splits.

Another embodiment is shown in FIG. 3 A shown in the hole in the burner head 3 a nozzle insert 14 provided with two channel-shaped nozzle channels 13 is arranged. This Nozzle insert 14 tapers at its upper end with an angle of about 90 ° between the conical lateral surfaces, while the burner opening 2 in a narrow area at an angle is widened conically from about 90 ° from the inside to the outside. When inserted, the tip of the Nozzle insert 14 arranged opposite the opening 2 of the burner head 3 so that their approach is still lies within the vertical bore 1 and it is just below the upper edge of the burner head 3 ends. In this way, particularly good flame guidance is achieved. If the gas pressure is too high, it will also here the flame is split into two partial flames 12. F i g. 3 B shows the arrangement of the two nozzle channels 13. Of course, you get the same effect if you use the nozzle insert instead of the channels attaches such in the wall of the bore 1 and uses an unmachined shaft as an insert 14. The number of nozzle channels 1 ', 13 can be selected as required, but two to four channels most appropriate.
