摘要

A coil assembly (44) comprising an electrical winding (50) included in an overmoulding (52), the winding (50) being suitable for controlling the control valve (14) of a fuel injector. The coil assembly (44) is provided with a longitudinal bore (54) suitable for receiving a spring (72) and an adjustment member (62) for adjusting the setting of the spring (72) which can be moved from outside the injector, the adjustment member (62) forming a movement transfer such that the movement of the adjustment member (62) from outside the injector (10) is transformed into a compression of the spring (72).
