ABSTRACT:
The discharge side of a fuel injection valve is covered by a disc forming a passage member adjacent the valve seat and a disc forming a nozzle member on the opposite side thereof, the passage member having central recesses on opposite sides, radial passages leading from the recess facing the valve seat to through holes at the radially outboard ends of the radial passages passing through the disc and opening up on the opposite face of the passage member to a similar number of passages which extend tangentially from a central circular recess to fluid communicate the small diameter nozzle discharge opening within the discharge member to the circular recess facing a concentric needle valve centered with the valve seat.
