A rotary spray nozzle includes an internal chamber, an inlet channel, a discharge channel for discharging fluid from the nozzle, and a rotor arranged within the internal chamber. The rotor includes an internal flow channel for transmitting fluid therethrough, a cup-shaped external channel concentrically arranged about a longitudinal axis of an external surface of the rotor body for temporarily retaining the fluid, and a rotor skirt arranged distal to the external channel. Fluid in the nozzle causes the rotor to spin and exerts a force on the rotor when briefly retained in the external channel and when contacting the rotor skirt to cause a rotor outlet to seal against a rotor seat such that fluid from the rotor outlet is discharged from the discharge channel in a continuous stream defining a circular spray pattern. The rotor may include a spherical region for frictionally engaging with the internal chamber.

Nozzle assemblies adapted to produce an oscillatory spray pattern. A rotor member having at least one lobe engaged with one or more cavities of a stator surface for defining an oscillatory movement of the rotor member in response to a motive fluid along the rotor member and stator surface. The nozzle assembly directing the motive fluid along one or more tapered surfaces, such as complementary tapered surfaces of the rotor and stator surface. The rotor member is operatively coupled with the spray member for oscillatory movement therewith. The spray member adapted to receive the motive fluid and emit the fluid as a spray from the nozzle assembly. The spray having an oscillatory pattern that matches the oscillatory movement of the rotor.

A rotor nozzle structure has a chamber deployed with a rotor connecting to the water outlet and an adjusting element, wherein the rotor nozzle is capable of generating a directing stream and a wide-angle swirl stream, and the adjusting element is switchable by a rotational means for driving the rotor in a rotation or static status in the chamber.

A device for distributing wine uniformly over a wine cap includes a T-joint member, an impeller and a shaft. The T-joint member has a top opening, a bottom opening, a side opening, a through-opening extending from the top opening to the bottom opening and a side-through-opening extending from the side opening to the through-opening. The impeller includes a one-piece conical shaped body that has a circular base, a cylindrical center, a conical-shaped outer surface, a central-through-opening extending through the cylindrical center, and a plurality of curved blades extending from the top of the cylindrical center along the inclined outer surface. The T-joint member is configured to allow wine to be pumped into the through-opening through the side opening and to exit through the bottom opening and then to flow onto the impeller. The impeller is configured to allow the wine to flow uniformly around and down the conical-shaped outer surface of the impeller and through the impeller.

A modular spray assembly for a spray head includes a stator having an inlet that can receive a flow of fluid. The modular spray assembly includes a cover coupled to the stator and having a first bearing disposed in the stator. The modular spray assembly includes an impeller rotatably coupled to the first bearing, in which the impeller includes a second bearing. The modular spray assembly includes a rotor rotatably coupled to the second bearing. The rotor can rotate eccentrically relative to the impeller by the second bearing. The impeller can rotate responsive to the inlet receiving the flow of fluid.

A fluid flow actuated tool including a housing, a tool and an actuating mechanism. The housing includes a housing interior. The housing interior receives a flow of fluid. The actuating mechanism includes a fluid wheel structure. The fluid wheel structure is connected to the tool. At least a portion of the fluid wheel structure is arranged in the flow of fluid for rotating the fluid wheel structure. The tool is actuated based on rotation of the fluid wheel structure.
