SYSTEM CONSISTING OF AN OIL PUMP AND OF A VALVE FOR OIL BURNERS

摘要

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 (1 1) goes through the borehole (12). The oil flow borehole (17) of the closing bo dy (16) complements the oil line (11) in a first position of the inventive magn et 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 i s thus prevented from dripping.
