A nozzle for producing an impacting pulsating spray of liquid comprises a hollow elongate tube having an inner chamber and a pair of spaced inlet and outlet plugs fitted one in each opposite end of the tube thereby to define the chamber. The outlet plug has an axial funnel-shaped duct defined therethrough with the flare of the duct open to the exterior of the nozzle. The inlet plug has a duct defined therethrough with its mean cross-sectional area substantially less than the mean cross-sectional area of the chamber. Liquid is fed into the chamber through the inlet plug and emerges out of the nozzle through the outlet plug as a randomly pulsating conical spray having a high impacting force.
