摘要

PROBLEM TO BE SOLVED: To solve the problems of high manufacturing cost, and long assembling time, since a solenoid actuator of a fuel injector of an internal combustion engine has a set of parts assembled so as to form a block composed of a nonmagnetic material for guaranteeing to electrically insulate a core and a coil provided with a contact point.;SOLUTION: The solenoid actuator 21 is formed of an integral assembly 53. This integral assembly 53 is provided by forming an integral assembly having the core and the coil, by defining a body 28 for insulating the core 23 from an injector body 2, when a plastic material is once solidified, by injecting the plastic material on the core 23 and the coil 24 mutually joined to a mold 50.;COPYRIGHT: (C)2006,JPO&NCIPI
