ABSTRACT:
The conical nozzle valve seat of a diesel injection nozzle is shaped to form a notch extending down from an annular upper notch boundary on the bottom face (seat) of the valve. The notch boundary is of a greater diameter than the annular entry edge of the sac and the minimum cross-sectional flow area of the valve is greater than that associated with an otherwise identical valve that does not have such annular notching.
