Abstract

The manufacturing method regards a servo valve (5) of a fuel injector, wherein a bushing (41) is designed to slide on a fixed stem for opening/closing the servo valve (5) and carries an armature (17), which is free to slide axially on the bushing (41); according to the method, the bushing (41) is provided in such a way that it has a guide portion (61) and an adjacent terminal portion (71); after the armature (17) has been mounted on the guide portion (61), a ring (73) is fitted on the terminal portion (71) so that it is brought in contact upon the armature; the ring (73) is then welded to the terminal portion (71) with weld material along a circumference so that a sight welding is carried out without any need for angular positioning between the bushing (41) and the welding device.
