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.

There is provided a spinner tip for hydrovacing or hydro blasting. The spinner tip comprises an inlet. The inlet has an inlet housing and a bore defining a bore axis. The assembly further comprises a drive chamber in fluid connection with the bore, and one or more openings each providing a fluid connection between the bore and the drive chamber. The one or more openings each define an opening axis. The opening axis of each of the one or more openings is at least partially offset from the bore axis to introduce rotation of fluid in the drive chamber. The assembly further comprises a rotor rotatably mounted within the drive chamber. The rotor providing a fluid connection between the drive chamber and a tip on the rotor.

The present invention discloses an eccentric swaying washing nozzle, including a housing, a jet hole, a nozzle, a fixing ring, a water wheel, a fixing cover, and the like. A nozzle ball head is arranged on a front end of the nozzle, and a plurality of evenly distributed circumferential external positioning ribs are provided on an outer circumferential surface of the nozzle ball head. A nozzle hole is provided in the nozzle, and the front end of the nozzle hole extends through the nozzle ball head and is in communication with the jet hole to form water outflow. In this way, when water entering the housing drives the water wheel to rotate and drives a rear end of the nozzle to perform circumferential eccentric rotation, the nozzle ball head can be driven to synchronously perform circumferential eccentric swaying relative to the jet hole under the restriction of the plurality of external positioning ribs, so that the water outflow at the jet hole is also spraying in a circumferential eccentric swaying manner. Obviously, such an eccentric swaying structure is easier to assemble and can effectively prevent the nozzle ball head from getting stuck accidentally. In addition, a double-layer wear-resistant washer is arranged between blades of the water wheel and the adjacent fixing ring to prevent the water wheel from getting stuck and affecting rotation. These structural improvements can improve usage reliability of the washing nozzle and extend a service life.
