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 valve (11). The oil is thus prevented from dripping.
Système composé d'une pompe à mazout et d'une vanne magnétique destinée à empêcher le mazout de goutter en cas d'arrêt du brûleur à mazout. Le système selon la présente invention comporte une pompe (23) à mazout et une vanne magnétique (10) pourvue d'un élément de fermeture (16) qui présente un passage (17) pour l'écoulement du mazout. L'élément de fermeture (16) est placé coulissant dans un trou (12) qui traverse une conduite (11) de mazout. Dans une première position de la vanne magnétique (10) selon la présente invention, le passage (17) d'écoulement du mazout de l'élément de fermeture (16) complète la conduite (11) de mazout, permettant ainsi l'écoulement du mazout. Dans une seconde position de la vanne magnétique (10), l'élément de fermeture (16) interrompt la conduite (11) de mazout. Dans cette seconde position est produit simultanément un vide partiel qui inverse le sens d'écoulement du mazout dans une partie terminale (15) de la conduite (11) de mazout, empêchant ainsi le mazout de goutter.
