Abstract (en)
[origin: EP0507233A2] In a burner for burning liquid fuel, in particular light fuel oil, - with an inner housing which surrounds a fuel pipe and in which primary combustion air can be conveyed, - with an outer housing which surrounds the inner housing at least partially and in which secondary combustion air can be conveyed, - with a housing opening of the inner housing, in the region of which a nozzle tip is arranged at the end of the fuel pipe, - it being possible to generate with the nozzle tip a fuel atomising cone, into which the primary and secondary combustion air can be introduced, - with a covering element which is movable in relation to openings in the outer and/or the inner housing, for changing the cross-section of the openings, and which is connected to a valve which controls the supply of the quantity of fuel to the fuel pipe, it is proposed that the valve has, in a valve housing, a displaceable rod piston, that there is arranged on the housing inside a projecting flange which surrounds the outside of the rod piston, and that the rod piston has on at least a part of its length a groove which is provided with variable depth over its length and which is not closed by the inside of the flange, which covers it. <IMAGE>
