A sprinkler having a nozzle for directing a desired flow of water therefrom, the sprinkler having a water turbine drive device for rotating the nozzle in response to water passing through the sprinkler; the sprinkler has a seal between its cover and housing and with a pop-up riser, the nozzle being mounted in a rotatable nozzle housing connected to the water turbine drive device; a deflector is mounted in the nozzle housing for moving into and out of the water flow from the nozzle, the deflector being connected to a pivotally mounted arm with a cam follower actuated by a cam on the top of the riser; a modified sprinkler has two flow passages therethrough to a primary nozzle and secondary nozzle, the flow to the primary nozzle being directed through the water turbine drive device while the flow to the secondary nozzle is through a valving device to produce a predetermined contour.

A sprinkler, said sprinkler having a rotatable nozzle housing, a nozzle in said housing to direct a flow therefrom, means for directing a flow of water to said nozzle, a deflector means within said nozzle housing for moving in or out of the flow directed from said nozzle during operation, a riser member, said rotatable nozzle housing being mounted for rotation on said riser member, cam means on said riser member for camming said deflector means into the flow directed from said nozzle during operation, said riser member having a groove means thereon, said cam means being located in said groove means, said cam means being resilient, means for changing the position of said cam means in said groove means to change the movement of said deflector means as said nozzle housing rotates, said groove being annular, said cam means being annular, and said cam means being formed with radial cuts to make it easier to change its position. A sprinkler having a rotatable nozzle housing, a cylindrical bore therein, a cylindrical nozzle positioned in said cylindrical bore, said cylindrical nozzle having an axis of rotation, said cylindrical nozzle having a nozzle outlet passage therein, said nozzle outlet passage having an axis at an angle to the axis of rotation of said cylindrical nozzle, the exit of said nozzle outlet passage being located at the center of said cylindrical nozzle so that as said cylindrical nozzle turns said exit of said nozzle outlet passage remains centered, means for rotating said cylindrical nozzle to change the position of the axis of said nozzle outlet passage around the axis of rotation of said cylindrical nozzle, means for directing a flow of water to said cylindrical nozzle, a deflector means within said nozzle housing for moving in or out of the flow of water directed from the centered exit of said nozzle outlet passage, the relationship of the deflector means and centered exit remaining the same as the position of the axis of the nozzle outlet passage is being changed.
