Abstract:
1. A sprinkler comprising: a sprinkler base connectable to a water supply; a nozzle attached to said base for directing water entering said base therefrom; a diffuser head rotatably attached to said base and having a water diffuser for diffusing water passing therethrough, said diffuser head being loosely connected to said sprinkler base to thereby allow said diffuser head to tilt and rotate on said base; a water deflector rotatably attached to said rotatable diffuser head for directing water emitted from said nozzle through said water diffuser, said water deflector having a water deflecting surface shaped to rotate said deflector and diffuser head with the water impinging thereupon from said nozzle; and a brake coupling said water deflector to said water diffuser to thereby vary the speed of rotation of said water diffuser relative to said water deflector; whereby a more even coverage of a sprinkled area is achieved by the different speed of rotation of said water deflector relative to said water diffuser.
