A rotating sprinkler for irrigation is disclosed. The sprinkler can include a stator spaced upstream from a turbine to form a mixing region therebetween. The stator can define a primary flow path and a bypass flow path. The primary flow path is aligned relative to the plurality of blades so that water exiting the primary flow path traverses the mixing region and impinges on the plurality of blades at a first angle of attack. The bypass flow path is aligned relative to the primary flow path so that water exiting the bypass flow path intersects the water exiting the primary flow path in the mixing region to cause the water exiting the primary flow path to impinge on the plurality of blades at a second angle of attack. The sprinkler can further include a valve configured to regulate flow between the primary flow path and the bypass flow path.

A rotor sprinkler is provided that includes a housing having a riser assembly and a rotatable nozzle turret on an upper end of the riser assembly. The rotor sprinkler includes an arc setting assembly that enables part-circle operation of the turret and a selector assembly that permits selection of either part-circle or full-circle mode of the nozzle turret where the full-circle mode rotates in one direction regardless of the direction last set in part-circle mode.

An oscillating sprinkler assembly includes a body including an inlet configured for connection to a water supply; a riser movably mounted in the body and movable from a retracted position to an extended position; a nozzle housing rotatably mounted on a top of the riser; a pressure regulating assembly mounted at an inlet of the riser and operable to control pressure of water into the riser based on an downstream pressure; a water turbine mounted downstream of the pressure regulating assembly such that water from the pressure regulating assembly passes through the water turbine to rotated one or more blades thereof, wherein the one or more blades are operatively connected to the nozzle housing and drive rotation of the nozzle housing; and a bypass valve, provided between the pressure regulating assembly and the water turbine and operable to control water flow to the water turbine.
