Abstract (en)

A fuel injector and a control valve used in it are disclosed. The control valve comprises: a valve seat defining a valve seating surface and a valve hole extending through a center portion of the valve seating surface in a longitudinal direction, the valve hole and the valve seating surface defining a longitudinal central axis, and the valve hole being in fluid communication with an injection valve of the fuel injector; a valve element configured to be moved between a closed position and an opened position along the longitudinal central axis, the valve element contacting and cooperating with the valve seat in the closed position to close the valve hole, and the valve element being moved away from the valve seat in the opened position to open the valve hole; and a holding block having an accommodating recess for holding the valve element; wherein the valve element is in the form of a solid of revolution, with the longitudinal central axis being the revolution axis of the solid of revolution, and the solid of revolution having a non-circular section in a longitudinal plane in which the longitudinal central axis lies so that the valve element is able to rotate around the longitudinal central axis but cannot rotate around any transverse central axis that is perpendicular to the longitudinal central axis.
