Beschreibung
Zusammenfassung:	A full cone spray nozzle comprising: a nozzle body (1) having a liquid inlet (3) at its upstream end and a spray orifice (4) at its downstream end; a vane structure (2) of an axial direction length (W) and diameter (D) arranged with its outer circumferential surface in contact with the inside of the nozzle body (1); has a plurality of channel grooves (6) of width (T) and depth (H) at the outer circumferential surface of the vane structure (2); an upstream side projecting part (8) of a length (U) in the axial direction of the nozzle body (1) at an upstream side of the vane structure (2); a downstream side projecting part (9) of a length (P) in the axial direction of the nozzle body (1) at a downstream side of the vane structure (2); and a swirl flow chamber (5) of an axial direction length (L) which is a space formed by an inside wall surface of the nozzle body (1), the vane structure (2) and the spray orifice (4), wherein 0.25¤T/D¤0.30, 0.25¤H/D¤0.30, and 1.5¤L/W¤3.5 are satisfied.
