Abstract

PURPOSE:To reduce the harmful magnetic flux density passing through a spring seat for enhancing the responsiveness of an open/close valve, in an electromagnetic fuel injector, by arranging the spring seat in a position behind the flange of a fixed iron core being connected with the end of a casing. CONSTITUTION:In an electromagnetic fuel injector, when an electromagnetic coil 9 is excited, magnetic flux passing through a fixed iron core 8, a movable iron core 25, and a casing 1 is produced, thereby an open/close valve 24 is attracted against a return spring 27 to open a fuel injection hole 22, so that pressurized fuel is injected. In this case, a spring seat 26 which holds the end of the return spring 27 on the opposite side to the open/close valve 24 is arranged in a position behind the flange 8b of a fixed iron core 8 being connected with the end of the casing 1. Thus, harmful magnetic path including the spring seat can be eliminated, and the magnetic flux density of flux passing through the normal magnetic path can be increased to enhance the responsiveness of the open/close valve 24.
