Abstract
A sprinkler apparatus 10 for providing more even coverage of a sprinkled area with water which is achieved by a different speed of rotation of a water deflector 13 relative to a water diffuser 12 in a wobbling sprinkler head. A diffuser head 11 is rotatably attached to a base 16 and has a water diffuser 12 for diffusing water passing therethrough. A water deflector 13 is rotatably attached to the rotatable diffuser head 11 for directing water emitting from the nozzle 21 through the water diffuser 12. A viscous fluid brake 15 couples the water deflector 13 to the water diffuser 12 to vary the speed of rotation of the water diffuser 12 relative to the water deflector 13 to obtain a more even coverage of the area being sprinkled.
Claims18
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.
A wobbling sprinkler comprising:
- a sprinkler base connectable to a water supply and having a collar having a predetermined plurality of gear teeth thereon;
- a nozzle attached to said base for directing water entering said base therefrom;
- a rotatable water deflector having a water deflector surface thereon positioned to deflect water from said nozzle, said water deflector having a base gear ring loosely attached under said base collar to allow said water deflector to be raised and rotated on said sprinkler base when water impinges upon said water deflector from said nozzle and said base gear ring having a predetermined plurality of gear teeth different from said base collar plurality of gear teeth to thereby allow only partial engagement of said water deflector base gear ring gear teeth with said base collar gear teeth thereby causing said water deflector to wobble and advance rotationally;
- and
- a water diffuser rotatably attached to said deflector for diffusing water deflected by said water deflector.
