Abstract
A fuel spray nozzle comprises a fuel passage () having at least one inlet and at least one outlet. The outlet is configured for accelerating fuel exiting the fuel passage into a jet. An air swirler () is arranged outboard of the fuel passage and converges to a single outlet chamber () adjacent the fuel passage outlet(s). The air swirler () can be nominally concentrically arranged but have some freedom to move axially or radially or change its angular position. The fuel passage outlets may be arranged symmetrically in an annular configuration. An air passage may be arranged axially within the annular array of fuel passage outlets.
