FIELD: electrical engineering; remote control mechanisms; electromagnetic fuel injectors. SUBSTANCE: valve includes detachable body where stop and armature with valve are mounted; electromagnetic coil is mounted in circular chambers provided in radial joints of body. Inner wall of circular chamber of body is provided with circular bores located on either side of wall. Bores are up to 2 mm wide and 0.6 to 0.5 mm thick. Total length of bores ranges from 4 to 10 of working clearances of armature. Body, stop and armature are made from plain electrical-sheet steel at diffusion layer of 0.2 to 0.3 mm deep which is saturated with nitrogen, aluminium, oxygen and carbon which also have nonferromagnetic phases. Diffusion layer possesses anisotropy of magnetic properties. EFFECT: enhanced efficiency. 3 cl, 2 dwg |
