Valve assembly for a fluid injection valve and fluid injection valve

A fuel injection valve, comprising:

• a valve assembly having a longitudinal axis and comprising a valve seat extending transverse the longitudinal axis, a valve disc extending transverse the longitudinal axis, and a valve stem extending along the longitudinal axis, wherein:
• the valve seat comprises an orifice laterally offset from the longitudinal axis,
• the valve disc comprises a fluid passage which, in a first angular position of the valve disc, overlaps the orifice at an interface of the valve disc and the valve seat to establish a fluid path through the valve disc and the valve seat, the fluid path extending through the valve disc parallel to the longitudinal axis for dispensing fluid from the valve assembly,
• the valve disc rotates around the longitudinal axis from the first angular position to a second angular position,
• the valve seat and the valve disc mechanically interact to seal the orifice in the second angular position,
• a spring directly pressing the valve disc against the valve seat, the valve stem mechanically interacts with the valve disc to rotate the valve disc around the longitudinal axis,
• the valve stem moves along the longitudinal axis with respect to the valve seat and is rotationally fixed with respect to the valve seat, and
• the valve stem is mechanically coupled to the valve disc such that an axial movement of the valve stem is converted to a rotational movement of the valve disc, and
• an actuator assembly configured to move the valve stem axially to thereby rotate the valve disc.
