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 rotary sprinkler in accordance with an embodiment of the present disclosure includes a riser with a nozzle assembly rotatable mounted thereon. The nozzle assembly includes a pressure regulator and flow control element.

A nozzle with an inlet and an outlet, including a shell, a rotor element located inside the shell and configured to be driven into rotation about a rotation axis upon being subjected to the action of a fluid flow entering the nozzle inlet and circulating through the nozzle towards the nozzle outlet, and a stationary splitter element located inside the shell, downstream of the rotor element, along the passage of the fluid flow. The rotation axis coincides with a main direction along which the fluid flow projects from the nozzle outlet. The rotor element includes peripheral helical grooves configured to permit passage of the fluid flow and cause rotation of the rotor element. The splitter element includes splitter openings communicating with a downstream end of the peripheral helical grooves to cause splitting and modulation of the fluid flow as a function of rotation of the rotor element with respect to the stationary splitter element. The nozzle further includes flow conditioning elements located inside the shell, downstream of the splitter openings, and configured to cause recombination of the fluid flow, split and modulated by the splitter element, into a pulsatile jet of fluid projecting from the nozzle outlet along the main direction that coincides with the rotation axis.

A water jet device for rotary massage includes a seat providing an outlet and a cavity; a cover providing an inlet; a separating member, a rotary shaft, an impeller and a rotor received in the cavity; at least one inclined water ejection port disposed on the separating member and communicating with the inlet; the impeller is mounted between the rotor and the separating member; the rotor is in the outlet, a plurality of curved grooves are formed on the periphery of the rotor; a track assembly includes an annular rail having ascending and descending sections formed on an inner bottom of the seat, and sliders formed on an underside of the impeller; water flowing through the water ejection port rotates the impeller, further drives the rotor to rotate, and the fluctuation of the impeller and the rotor drives the water fluctuates, thus form intermittent and dynamic annular water sprays.

A sprinkler can include a nozzle turret having a removable nozzle carrier. For example, the nozzle carrier can be removably installed within a recess of a nozzle housing. The nozzle carrier can include one or more nozzle ports configured to receive sprinkler nozzles. The nozzles can have varying characteristics including flow rate, output range, spray pattern, etc. In some cases, a primary nozzle can be removably coupled with the nozzle carrier. The primary nozzle can include a body (e.g., inlet) portion having a first axis and a tapered (e.g., outlet) portion having a second axis non-parallel to the first axis. The primary nozzle can be configured to be installed in the nozzle carrier in at least two orientations. In some cases, one or more secondary nozzles are removably or permanently connected to the nozzle carrier.
