Fuel injection valve has valve element to stop fuel injection through orifices of orifice plate if valve element is resting on valve seat, and to allow fine spray of fuel through orifices if valve element is away from valve seat

摘要

The fuel injection valve has an orifice plate (50) with a number of fuel injection orifices (60), and a valve element to stop the fuel injection through the orifices if the valve element is resting on the valve seat of the valve component of the fuel injection valve, and to allow a fine spray of fuel through the orifices if the valve element is away from the valve seat. At least the outlet side opening (62) of each injection orifice is created in a flattened form with a large and a small axis. Independent claims are also included for the following: (a) a fuel injection orifice plate for a fuel injection valve; (b) a valve component for a fuel injection valve; and (c) an injection orifice element for a fuel injection valve.
