Solenoid valve for controlling quantities of liquid

Solenoid valve for controlling quantities of liquid, particularly for injection systems, the solenoid valve (5) being arranged in a liquid line (4) which leads from a low-pressure space (feed pump 2) to a working space (9) at a different pressure (pump working space), with the result that the soleno...

Zusammenfassung:	Solenoid valve for controlling quantities of liquid, particularly for injection systems, the solenoid valve (5) being arranged in a liquid line (4) which leads from a low-pressure space (feed pump 2) to a working space (9) at a different pressure (pump working space), with the result that the solenoid valve (5) is periodically exposed to the high pressure in the working space (9). To cope with these relatively high loads, the solenoid valve (5) is of two-stage design with two magnet coils (27) in order, in the shut-off position, to move the transverse groove (22) on the control slide (18) further away from the control grooves (21) in the valve housing (16) in this high-pressure range than at lower pressure.
