Abstract
Abstract A nozzle body is formed with a fuel discharge chamber. A discharge valve opens into the chamber at one end and discharge orifices open from the chamber at the other end at various angles. The axial distances between the orifices and the valve are selected in accordance with the angles in such a manner that the fuel flow paths from the valves to the respective orifices have the same curvature and equal amounts of fuel are discharged through the orifices.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
197 words
A fuel discharge nozzle comprising: a nozzle body defining a fuel discharge chamber therein; a fuel discharge control valve opening into the chamber for controlling flow of fuel thereinto; the nozzle body being formed with pairs of diametrically opposed fuel discharge orifices opening from the chamber with each orifice of a pair being spaced from the valve along an axis of the chamber, each of the orifices being circumferentially spaced from one another about the axis of the chamber, the orifices opening from the chamber and each orifice of a pair having axes which intersect the axis of the chamber at different angles respectively, points of intersection of the axes of each orifice of a pair of the orifices with the axis of the chamber being spaced from the valve by distances which increase with the angles, axial distances of each orifice of a pair of the orifices from the valve being such that the fuel flows from the valve through the chamber to each orifice of a pair of the orifices along respective fuel flow paths of substantially equal curvature, whereby equal amounts of fuel are discharged through each orifice of a pair of the orifices.
