Abstract
Abstract The specification describes a nozzle for welding, heating, cutting and/or flame cleaning, comprising a cutting oxygen duct with an internal mixing device, arranged in the nozzle head, for heating gas and heating oxygen. There are also metering channels, possibly arranged around the centrally placed oxygen duct, for heating gas and heating oxygen. The heating oxygen metering ducts and the heating gas metering ducts open separately into a mixing chamber. From the mixing chamber an annular heating mixture duct leads to the gas outlet nozzle shank end.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A nozzle for welding, heating, cutting, flame cleaning and the like comprising a shank having a substantially central oxygen duct extending axially therethrough to terminate in an outlet opening, a heating gas duct and a heating oxygen duct formed in said shank and extending through said shank substantially parallel thereto, one of said ducts being of a shorter axial length than the other and opening into an annular chamber formed in said nozzle intermediate its ends, a second annular chamber formed in said nozzle at a point spaced from the end of said shorter duct and the other of said ducts opening to said second annular chamber, a first annular passage connecting said first annular chamber and said second annular chamber and a second annular passage connected with said second annular chamber and extending to the end of said nozzle to form an annular outlet disposed around said oxygen outlet opening.
Claim 2
Dependent Claim
151 words
A nozzle for welding, heating, cutting, flame cleaning and the like comprising a shank having a substantially central oxygen duct extending axially therethrough to terminate in an outlet opening, a heating gas duct and a heating oxygen duct formed in said shank and extending through said shank substantially parallel thereto, one of said ducts being of a shorter axial length than the other and opening into an annular chamber formed in said nozzle intermediate its ends, a second annular chamber formed in said nozzle at a point spaced from the end of said shorter duct and the other of said ducts opening to said second annular chamber, a first annular passage connecting said first annular chamber and said second annular chamber and a second annular passage connected with said second annular chamber and extending to the end of said nozzle to form an annular outlet disposed around said oxygen outlet opening.
Claim 3
Dependent Claim
58 words
The invention as defined in claim 1 and in which said shank has a reduced end portion, a nozzle ring being mounted to said reduced end portion, said first annular chamber, said first annular passage, said second annular chamber and said second annular passage being formed intermediate said reduced end portion of said shank and said nozzle ring.
Claim 4
Dependent Claim
53 words
The invention as defined in claim 2 and in which said nozzle ring is formed with several internal steps, a first largest step being provided with means for attaching said nozzle ring to said shank, a second largest step forming said first annular chamber, a third largest step forming said second annular chamber.
Claim 5
Dependent Claim
36 words
The invention as defined in claim 2 and in which the inner wall portion of said nozzle ring is conical intermediate said first annular chamber and said second annular chamber to form said first annular passage.
Claim 6
Dependent Claim
37 words
The invention as defined in claim 2 and in which the inner wall portion of said nozzle ring is conical intermediate said second annular chamber and the end of said nozzle to form said second annular passage.
Claim 7
Dependent Claim
31 words
The invention as defined in claim 1 and including a fourth duct extending completely through said shank and having an outlet radially spaced from said outlet opening of said oxygen duct.
Claim 8
Dependent Claim
22 words
The invention as defined in claim 6 and in which said fourth duct is adapted to be connected with a heating gas.
Claim 9
Dependent Claim
30 words
The invention as defined in claim 6 and in which the fourth duct has a diameter greater than the diameters of the heating gas duct and the heating oxygen duct.
