Abstract
To improve the oil supply and to prevent retarded dripping of oil from an oil burner nozzle when the burner flame has been extinguished, oil supply members are made of a heat-insulating material and positioned in the interior. The oil supply in the nozzle is provided by a oil filter with one or a plurality of solid porous bodies having narrow oil supply conduits. It has been shown that a porous plastic material, in particular a sintered plastic material, is advantageously suited for this purpose. The nozzle head, which can be screwed directly into the oil pre-heater, may comprise a metal with good heat conducting properties or a ceramic material and, in contrast thereto, the oil supply members submerged into the oil are made of a heat-insulating material. Thus, it is not only possible to manufacture the oil burner nozzle in a cost-effective manner, but it also has a considerably improved dripping effect, particularly if the oil supply members have a resistance control because of appropriate porosity or a sponge-like structural design.
