Patent ID: 6869032

Claim:
A fuel injector for a fuel injection system of an internal combustion engine, the fuel injector having a longitudinal valve axis, comprising: an actuator; a valve seat element including a stationary valve seat and an outlet orifice downstream from the stationary valve seat; a valve needle movable by the actuator and cooperating with the stationary valve seat to open and close the fuel injector; a swirl element situated upstream from the stationary valve seat; and a perforated disk attached to the valve seat element including an aligned orifice; wherein the outlet orifice opens directly into the aligned orifice in the perforated disk, a length of the outlet orifice in the valve seat element in a direction of flow being greater than a length of the aligned orifice in the perforated disk, and a width of the outlet orifice being greater than a narrowest width of the aligned orifice, and wherein the outlet orifice is inclined with respect to a longitudinal valve axis.
