Abstract

A nozzle for spraying a medium under pressure has a selectable form of jet. A knife edge body is rotatably mounted in front of the outlet from the nozzle bore, and has a front knife edge which breaks the jet from the bore into a spray mist when that knife edge is rotated into the jet and a rear knife edge which spreads the jet to a fan-shape when it is rotated into the jet.
