Abstract
A valve assembly for a fluid injection valve has a longitudinal axis and includes a valve seat and a valve disc. The valve seat has an orifice that is laterally offset from the longitudinal axis. The valve disc has a fluid passage which, in a first angular position of the valve disc, is positioned in such fashion that it 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 for dispensing fluid from the valve assembly. The valve disc is rotatable around the longitudinal axis with respect to the valve seat from the first angular position to a second angular position, wherein the valve seat and the valve disc mechanically interact to seal the orifice in the second angular position.
