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).
