Abstract
What is disclosed is an improved sprinkler utilizing a nutation mechanism. The sprinkler utilizes a race having an upper limit and lower limit. The tire is connected to the distributor. Water sprays on the distributor causing the nutation of the device in which the tire moves between the upper race and lower race limits. The sprinkler includes a separate starting mechanism on which a starting bump is positioned on a distributor support.
Claims4
A liquid distributing sprinkler head, comprising,
- a housing, with an attached nozzle, said nozzle connected to an adapter to be attached to an incoming liquid supply;
- a tire carrier assembly comprising of a tire and a lower tire;
- a distributor with said distributor hanging loosely from an arm holder, said distributor with a lower plate, said lower plate held in a spaced apart relationship by one or more arms connected to a swashing ring;
- said lower plate having a lower plate first side having a generally peaked surface profile with an upturned edge at the periphery of the plate, said surface incised by spirally radiating grooves with a peak on said lower plate first side centrally positioned and having a beveled top surface;
- wherein
- said distributor is configured to hang freely from said swashing ring when distributor is idle, with said bevel on said lower plate configured to be deflected by an initial jet of liquid from an incoming liquid supply that travels through said sprinkler, and for the distributor to begin a nutation motion after said initial deflection with said nutation motion maintained by the force of liquid on said spirally radiating grooves;
- and
- said arm holder comprises a starting bump, wherein said swashing ring rests on said starting bump when sprinkler is idle causing said distributor to tilt allowing for initialization of nutation motion.
