Abstract
The invention relates to a system made of an oil pump and of a magnet valve for preventing oil from dripping when the oil burner is switched off. The inventive system is provided with an oil pump (23) and a magnet valve (10) which has a closing body (16) that comprises an oil flow borehole (17). The closing body (16) is displaceably located in a borehole (12). An oil line (11) goes through the borehole (12). The oil flow borehole (17) of the closing body (16) complements the oil line (11) in a first position of the inventive magnet valve (10). The oil flow is thus released. The closing body (16) interrupts the oil line (11) in a second position of the magnet valve (10). A vacuum is simultaneously generated in said second position. The vacuum reverses the direction of oil flow in an end section (15) of the oil line (11). The oil is thus prevented from dripping.
