A full cone spray nozzle, particularly for liquids bearing fibrous particles and the like, having a pair of swirl imparting vanes within the bore of the nozzle. Transversely of the bore, the vanes are approximately semi-circular segments, each having a central recess to provide an opening for liquid flow in axial alignment with the outlet orifice of the nozzle. The vanes overlap circumferentially on diametrically opposite sides of the opening. In the direction of liquid flow, each semi-circular segment is generally sinusoidal, having a convex loop in one quadrant of the passage facing upstream and a concave loop also facing upstream in an adjacent quadrant of the passage. The curved loop portions of each vane are interconnected by an axially extending leg which cross at about the center of the bore and being recessed define the central opening.
