Abstract
A rotary stream sprinkler unit comprises a body having a water flow passage in which is disposed a flow control unit having a variable restriction in a passage to one or more arcuate passages configured to control the volume and pressure of a primary stream delivered to a rotary distributor head rotatably mounted at the outlet of the housing for dividing each primary stream into a plurality of final streams and rotating each of the final streams through a selected arc during the rotation of the rotary head.
Claims22
A rotating stream sprinkler unit comprising:
- a tubular housing having a central axis, an inlet, an outlet, and a flow passage communicating therebetween for conducting a stream of water from said inlet to said outlet;
- orifice means at said outlet for receiving and forming said stream of water into at least one substantially arcuate primary stream directed axially outward from said outlet;
- and
- a rotating distributor head rotatably mounted at and spaced axially outward from said outlet having a plurality of flow channels therein for receiving and forming said primary stream into a plurality of streams and directing said plurality of streams outward from said axis over a predetermined area;
- and
- means for selectively blocking a portion of said flow passage for selectively adjusting the quantity of water in said stream of water communicated to said distributor head.
A rotary stream sprinkler unit comprising:
- an elongated generally cylindrical housing having coaxially disposed inlet and outlet means at opposite ends thereof;
- a flow passage in said housing for communicating a fluid flow from said inlet to said outlet;
- orifice means at said outlet of said housing for generating at least one generally arcuate thin wide flow stream directed axially outward at said outlet thereof;
- and
- a rotating distributor head having a plurality of open stream channels disposed axially outward from said outlet for receiving and directing said flow stream in a plurality of streams over selected areas;
- and
- means in said flow passage for adjustably restricting the flow therein.

- orifice means at said outlet of said housing for generating at least one generally arcuate thin wide flow stream directed axially outward at said outlet thereof, said orifice means comprises a sleeve detachably mounted in said housing, and said arcuate passage formed in and extending along said sleeves;
- a rotating distributor head having a plurality of open stream channels disposed axially outward from said outlet for receiving and directing said flow stream in a plurality of streams over selected areas;
- and
- means in said flow passage for adjustably restricting the flow therein.
