Lever Device and a Fuel Injection Valve

A fuel injection valve, comprising:

• a lever device comprising:
• a housing having a housing recess,
• at least one lever element, each arranged in the housing recess and having a coupling portion coupled to a portion of the housing,
• a drive element arranged in the housing recess and coupled to the at least one lever element to act on the at least one lever element along a longitudinal axis, and
• an output element arranged in the housing recess and coupled to the at least one lever element such that the output element is moveable along the longitudinal axis by the at least one lever element,
• wherein for each lever element, the coupling portion has a recess that defines at least two contact faces of the coupling portion that are spaced apart from each other and lie on the portion of the housing, and
• a valve needle coupled to or defining the output element,
• wherein the drive element and the valve needle are coupled together via the lever device such that a closed position of the valve needle prevents a fluid flow through the fuel injection valve and other positions of the valve needle allow a fluid flow through the fuel injection valve.
