摘要

PROBLEM TO BE SOLVED: To assemble and test a valve group and a coil group independently by modularizing a fuel injector.;SOLUTION: The fuel injector has a valve group subassembly and a coil group subassembly. The valve group subassembly has a pipe assembly, a seat, a lift sleeve, an armature assembly, a member for pressing the armature assembly toward the seat, an adjusting pipe for engaging the member and adjusting the pressing force of the member, and a first mounting portion. The coil group subassembly has a solenoid coil and a second mounting portion fixedly connected to the first mounting portion.;COPYRIGHT: (C)2002,JPO
