US Patent 10570865 Fuel injector with variable flow direction

A fuel injector and method are disclosed wherein an injector body defines a cavity and passages from an inlet at the cavity through an outside surface of the injector body. Each passage may have a first inner contour at a first angle and a second inner contour at a second angle. An injector pin with a fuel pass-though volume may be movable within the cavity to selectively overlap an outlet of the pass-through volume with an inlet of the passages to selectively direct fuel in varying quantities along the first second inner contours.
