Abstract
An oil burner for heating systems includes an atomizer nozzle placed in or connected to an oil feed pipe and a shutoff element is arranged in the oil feed pipe which has a blocking element which can be moved by the inflowing oil, within limits. The blocking element or a part adjacent the oil flow conduit are formed either entirely or partially from a permanent magnet and one can be moved into the closed position by its magnetic force to reliably prevent dripping of the oil from the atomizer nozzle after completion of a combustion process.
