SPRAY NOZZLE WITH SWIRL CHAMBER PROVIDED WITH A FRONT END REAR ANNULAR RIB FOR OUTLET PASSAGE |
摘要 |
The invention concerns a spray nozzle comprising a central swirl chamber (9) in the rear part whereof the fluid to be sprayed penetrates in a vortex through fluid intake channels (14). The fluid exits the central swirl chamber (9) through a cylindrical or slightly conical coaxial outlet passage (12) converging towards the outlet, and whereof the inlet orifice (29) is flanged with a rear front end annular rib (30) itself enclosed by a free annular front portion (33) of the swirl chamber, thereby reducing the minimum flow rate of the nozzle, and the size of the sprayed fluid droplets.
