A fluid nozzle 10 for a gas turbine engine fuel injector has a body 14 which has an annular cavity 18 that extends out one axial end 22 of the fluid nozzle. At least one port 26 is fluidically connected to an annular chamber 30 of the annular cavity, the annular cavity being defined between a radially inner surface 38 of the body and a radially outer surface 34 of the body. A first portion 42 of the radially outer surface has a first radial dimension 46 smaller than a greatest radial dimension 50 of the at least one port, and a second portion 54 of the radially outer surface, further from the annular chamber than the first portion of the radially outer surface has a second radial dimension 58 greater than the first radial dimension. In use, fluid flowing through the nozzle in an axial direction from the port impinges against the radially outer surface of the annular cavity thus redirecting the fluid to flow radially before redirection to once more flow substantially axially. |
