Embodiment Construction

[0009] refer to figure 1 . It is mainly composed of iron core 1, coil 2, coil skeleton 3, armature 4, magnetic isolation ring 5, outer shell 6, inner shell 7, valve stem 8, valve seat 9, armature accessories 10, valve stem spring 11 and The intermediate housing 12 is formed. They are assembled together as shown to form an electronically controlled fuel injection fast solenoid assembly.

[0010] The magnetic isolation ring 5 and the inner casing 7 are assembled on the lower stepped axial end surface of the iron core 1 , and the magnetic isolation ring 5 is located between the lower stepped end surface of the iron core 1 and the inner casing 7 opening end surface. The coil 2 surrounding the stepped cylinder of the iron core 1 through the bobbin 3 is closely attached to the upper cylindrical surface of the inner casing 7 . The coil bobbin 3 is positioned in the annular slot on the lower end surface of the intermediate housing 12 and assembled in the cylinder of the outer housing

Abstract

The invention discloses an electronic fuel injection (EFI) rapid electromagnet which can eliminate stiction of an armature in release so as to speed up release. The invention is realized by the following technical scheme that an insulation magnet ring (5) is arranged at the position at which the distance between the end surface of the step below an iron core (1) and the end surface of a waist gap delta 1 of an internal shell (7) is L, so that the generated total flux is divided into two paths, wherein one path passes through an iron core (1), a middle shell (12), an external shell (6), a gap delta 2 between the inside diameter of the internal shell (7) and the outside diameter of the armature (4), the armature (4) and a gap delta1 between the upper plane of the armature (4) and the lower end surface of the iron core (1), so as to form a first loop flux phi 2; and an internal shell (7) and the external diameter of the armature (4); and the other path passes through the iron core (1), the middle shell (12), the external shell (6), and the internal shell (7), passes by the armature (4), and directly returns to the iron core (1) by passing through the internal cylindrical surface of the internal shell (7) and the external cylindrical surface of the iron core (1), so as to form a second loop flux phi 1.
