A spray nozzle (1) has a pre-chamber (39) and a mixing region (32). A first inlet (12) defines a first fluid flow path for admittance of a first fluid to the pre-chamber (39). A second inlet (14) defines a second fluid flow path which is crossed by the first fluid flow path for admittance of a second fluid to the pre-chamber (39). A wall (21) is positioned between the pre-chamber (39) and the mixing region (32) and has an aperture (22) therethrough coaxial with the first fluid flow path. Fluid can pass from the mixing region (32) out of the spray nozzle (1) through an outlet (36), the outlet (36) not lying on the first and second fluid flow paths. A first fluid entering through the first inlet (12) mixes with a second fluid entering through the second inlet (14) in the mixing region (32) prior to the mixed first and second fluids passing out through the outlet (36).
