1. A rotating stream sprinkler unit comprising:
- an elongated tubular housing having a central axis, an inlet at one end, an outlet at the opposite end, and a flow passage communicating therebetween for conducting a flow of water from said inlet to said outlet;
means including a plurality of elongated flow control passages having an inlet end and an outlet end in said housing member disposed in a circular array around and extending along said axis toward the outlet for dividing said flow of water into a plurality of streams; and
a rotating distributor head having an outer surface of a generally concave frusto-conical configuration rotatably mounted co-axially of said housing at said outlet, said head having an inner end defined by an apex adjacent the outlet of said flow passage, a plurality of symmetric flow channels formed in the outer surface of said distributor head individually receiving and directing each of said plurality of streams over a predetermined area as it passes over each passage.

Abstract
A rotary stream sprinkler unit comprises a body having a water flow passage in which is disposed a multi-passage flow control unit having a plurality of passages, each configured to control the volume and pressure of a stream with multiple outlets at the outlet end of the housing, and a rotary distributor cap rotatably mounted at the outlet of the housing for rotating each of the outlet streams through a selected arc during the rotation thereof.

10. 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; flow stream generating means comprising a plurality of elongated passages in said housing for generating a plurality of separate flow streams at said outlet, each of said elongated passages having a length that is at least twice the diameter thereof, at least one of said elongated passages having a different configuration for delivering a flow stream therefrom at a different distance than at least another of said plurality of said elongated passages; a rotating distributor head having an axis and an inverted generally concave frusto-conical configuration with the apex thereof at said outlet, a plurality of open stream channels extending radially outwardly along the outer surface thereof in a common plane with said axis for receiving and directing each of said flow streams individually over selected areas; and drive means for driving said distributor head at a controlled rate of rotation. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A rotating stream sprinkler unit comprising:
-
an elongated generally cylindrical tubular housing having an inlet, an outlet, and a flow passage communicating therebetween for conducting a flow of water from said inlet to said outlet; means comprising a plurality of elongated passages distributed in a circular array about the axis of said housing for dividing said flow of water into a plurality of streams at said outlet; a rotating distributor head having an axis and a generally concave frusto-conical outer surface, a plurality of open flow channels in and extending generally axially along said outer surface, said distributor head rotatably mounted at said outlet for receiving said streams and directing said streams individually via said flow channels over a predetermined area; and a turbine in said flow passage responsive to flow of water therein for rotating said distributor head. - View Dependent Claims (18, 19)
