Abstract
A spray emitter (10) has a fixed head (11) and a rotary deflector (22). The head (11) has a jet passage (14) extending through it to direct a jet of water onto a central point (24) of the deflector where its deflecting surface (23) converges. The converging surface closes the mouth of the jet passage (14) under no flow conditions but is lifted away from the mouth under the water flow conditions, and the water flowing upwardly over the deflector surface (23) is intercepted by blades (28) which extend outwardly from the upper portion of the deflector surface. The spray is emitted as a plurality of streams each having a large component of horizontal direction so as to provide a low trajectory.
