ELECTROMAGNETIC VALVE Russian patent published in 1998 - IPC

FIELD: manufacture of fittings. SUBSTANCE: armature is located in cavity of electromagnetic valve electromagnet between cover and stop. Control cavity of body and pressure line are brought in communication by means of loading passage. Piston is made integral with main shut-off member where unloading passage is made. Passed through axial passage of piston and main shut-off member is rod connecting the armature of electromagnet and reversible control shut-off member. Main shut-off member made from ferromagnetic material is mounted in yoke of electromagnet; movable stop is rigidly connected with ferromagnetic piston. Armature may be made in form of separate part connected with control shut-off member through spring-loaded rod. Loading passage may be made in movable stop and movable stop is sealed in electromagnet. EFFECT: enhanced reliability. 4 cl, 4 dwg
