JOHAN VICTOR svENsoN, or AUGos'rnnneL, STOCKHOLM, SWEDEN BURNER FOR Application filed October 17, 1927, Serial No.
The present invention relates to an improvement in such burners for liquid fuel in which below the nozzle, through which the evaporated fuel escapes, is provided a vaporizing chamber wherein is placed a heat storing vaporizing member provided with passages. This vaporizing member has hitherto been only loosely inserted in the Vaporizing chamber, causing the disadvantage that said member, especially when the burner has been in use for some time, will be out of necessary metallic contact with the walls of the chamber, even if it, when inserted, was in such a contact with said walls, resulting l5 in an inadequate transmission of heat from the walls of the chamber to said member. A loose insertion of said member in the vaporizing chamber involves, however, also other disadvantages. Tt is evident that the fuel when being forced up in the vaporizing chamber ought to be evenly and continuously evaporated in accordance with its entrance into that part of the chamber where vaporization temperature is prevailing, but in a chamber Where the vaporizing member is inadequately heated and besides loosely inserted and even has an opportunity to change position or is somewhat movable in the chamber, the vaporization will in a great degree be uneven and thus create a pulsating stream of vaporized fuel according as a quantity of fuel new and then is suddenly evaporated. The consequence hereof is that the flame will be uneven and if the vaporizing member then has an opportunity to displace itself in the chamber the e'ect of such a displacement may be that every time it takes place a clearly audible blow is noticed. The eifect of such blows may be that small colte-like particles may be 40 detached from the vaporzing member 0r the container, an explosion may take place, as the main part of the container then is filled with y air mixed with vaporized fuel.
This invention has for its Object to eliminate said disadvantages and is chiefly 5o characterized thereby that the vaporizing LIQTD FUEL 226,753, and in Sweden November 20, 1925.
member at its lower end is effectively acted i.
upon by a member the effect ofv which is to force the vaporizing member upwards in good contact with the walls and upper end i of the vaporizing chamber. i
One form of construction` of a burner provided with a vaporizing chamber and a Vaporizing memberfof the kind in question and with an arrangement according to this invention are illustrated as an example on the accompanying drawing in a vertical section.
Below the Ynozzle Il,y through which the evaporated fuel y escapes, is the vaporizing chamber 2' wherein the vaporizingv member 3 is placed. This latter has the same cross sect tional shape as the vaporizing chamber and is of such size, that it all round along its entire length and preferably also at. the upper'end will be in good contact with the walls of thechamber. rThe Vchamber 2' may be of; the same cross section all over but preferably it is tapering vsomewhat upwards in order that the member 3 .whioh is of the same shape, may better and more firmly, all over, come in goed contactwith the walls of the chamber;
the member 3. This may suitably be manufactured of wire-gauze but it may alsojconstit-ute a 'solid body of some suitable metal, t. in which case the same must be provided with suitable passagesA in which the fuel that passes through the same may be vaporized.
It is obvious that the above indicated disadvantages are eliminated in a burner the vaporizing member of which is kept in its place by an arrangement according to this invention.
Having now described my invention what I claim as new and desire to secure by Letters Patent is:
l. A burner for liquid fuel, including a nozzle for the passage of vaporized fuel, a nozzle supporting member having a Vaporizing chamber located below the nozzle, a heatl storing vaporizing member located Within said chamber and provided with passages, and a member movably mounted in the supporting member adapted to exert pressure 5 upon the Vaporizing member to maintain the latter in close Contact with the supporting member.
2. A burner for liquid fuel, including a nozzle for the passage of vaporized fuel, a
nozzle supporting member having a vaporizing chamber located below the nozzle, a heat storing vaporizing member located within said chamber and provided with passages, and a member movably mounted in the supporting member adapted to exert pressure upon the Vaporizing member to maintain the latter in close contact Vwith the supporting member, said last mentioned member being` of annular form and being located wholly 2'0 within the supporting member.
3. A burner for liquid fuel, including a `nozzle for the passage of vaporized fuel, a nozzle supporting member having a vaporiz- Ying chamber located below the nozzle, a heat storing vaporizing member located within said chamber and provided with passages, and a membermovably'mounted in the supporting member adapted to exert pressure upon the vaporizing member to maintain the latter in close contact with the supporting member, said vaporizing chamber and the storing member being of tapered form whereby to produce a wedging effect 0n the latter member.
` 4. A burner for liquid fuel, including a nozzle for the passage of vaporized fuel, a nozzle supporting member having a vaporizing chamber located below the nozzle, a heat storing vaporizing member located Within said chamber and provided with passages,
and a member movably mounted in the supporting member adapted to exert pressure upon the va-porizing member' to maintain the latter in close contact with the supporting -member, said last mentioned member being annular and externally threaded and located wholly Within the supporting member.
In witness whereof I have hereunto set my hand.
