ELECTROMAGNETIC DRIVE OF CONTROLLING VALVE Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: electromagnetic drive of controlling element of predominantly metering valve of fuel pump has body 1, electromagnet having magnetic circuit 3 with winding 4 that is distributed one and is so placed in straight parallel slots 5 of magnetic circuit 3 that element 8 of magnetic circuit 3 separating two adjacent slots 5 is core of part of winding. Number of slots 5 in this case is three as minimum. Armature 6 is manufactured in the form of plate of round shape coupled to guide of movement of armature. Winding 4 of electromagnet can be fabricated in the form of package of flat conductors. Magnetic circuit 3 can be so bladed that sheets are arranged perpendicular to slots 5 of magnetic circuit. Guide of movement of armature can be manufactured in the form restoring membrane. EFFECT: increased speed of response, enhanced developed force and adaptability to manufacture of proposed electromagnetic drive. 4 cl, 5 dwg
