<p>A swirler for a fuel spray nozzle comprises a body (30) having a longitudinal axis and an annular array of V-shaped slots (58) defined on a frusto-conical portion (56) thereof. The frusto-conical portion is adapted to be engaged with an annular mating inner surface (60) of the fuel spray nozzle to define therewith a plurality of fluid swirl passages. By having V-shaped slots rather than the conventional square or rectangular slots, a range of swirlers having different flow characteristics may be produced with a unique cutting tool.</p> |
