Abstract
A fuel injector has a housing with a central longitudinal axis having a first cavity and may be coupled to a fuel rail having a fluid inlet portion and outlet portion. The fuel injector has a valve needle arranged at least partly within the housing axially movable in the first cavity facing the fluid outlet portion, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing it through the fluid outlet portion in further positions. The fuel injector has a spring arranged within the first cavity for exerting a spring force on the valve needle along the central longitudinal axis for preventing the fluid flow through the fluid outlet portion. Additionally, the fuel injector has an adjusting element for adjusting an axial position regarding the central longitudinal axis of a spring rest depending on a pressure acting on the adjusting element.
