A structure of rotor nozzle is equipped with a spray unit of a watering device, the spray unit is composed of a mounting member and a housing for defining a chamber, a rotor deployed inside the chamber; wherein, at least one stopper set on the inner side of the chamber near the water outlet side is correspondingly matched to multiple guide members on one end of the water outlet of the rotor, and it can be employable to the handy watering device.

An improved nozzle assembly for use with a sprinkler body. The nozzle assembly has a nozzle body having a recess and defining a fluid flow path through the nozzle assembly. A nozzle insert is positioned in the nozzle body and retained by a keeper tab that is positioned through an opening in a rear wall of the recess. The nozzle insert is rotatable between a series of operational positions including the IN (or insertion) position, the RUN position, the OFF position, the FLUSH position, and the LINE FLUSH position. A biasing plate is positioned on the face of the nozzle body and is configured to detent the turning knob of the nozzle insert in the RUN position. Further provided is a nozzle insert carrier configured to retain additional, not-in-use nozzle inserts with the nozzle assembly.

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.

Apparatuses, systems, and methods are disclosed for a spray nozzle 100, 200, 600. A spray nozzle 100, 200, 600 includes a housing 102 with an inlet 104 and/or a nose cone 106. An axis of an inlet 104 is disposed perpendicular to an axis of a nose cone 106, the housing 102 comprising an internal chamber formed within the housing 102. A spray nozzle 100, 200, 600 includes a nozzle holder 204. A nozzle holder 204 is disposed within an internal chamber of a body. A nozzle holder 204 is secured at a nozzle seat 202 coupled to a nose cone 106. A distal end of a nozzle holder 204 is free to rotate within an internal chamber of a housing 102 along a conical path having a vertex at approximately a nozzle seat 202 of a body. A nozzle holder 204 comprises an internal fluid channel to direct a fluid stream from a distal end of the nozzle holder 204 to a nozzle seat 202.

A spray gun includes a barrel having a path between an entrance and an outlet. A guide member is connected to the outlet. A rotary member has a tapered way defined therein, and a Venturi tube is partially located in the tapered way. A spray head is connected to the front end of the barrel and has an orifice defined in the spray head. A room is formed by the guide member and the spray head. The rotary member is located in the room. Pressurized liquid passes through the path and enters into the room to rotate the rotary member, and the detergent is sucked by the Venturi tube and spread out from the orifice in a rotational pattern.

The present utility model provides an anti-drip rotatable sprayer, which is characterized in that: an inlet pipe and an outlet pipe are interconnected to pass through two opposite sides of the sprayer on the casing, the casing is provided with a reduction gear set driven by the driving shaft lever passing through the casing. The driving shaft lever passing through the casing is provided with a turntable, the inlet pipe passing through is provided with a nozzle to spray the water column towards the turntable, the turntable drives the reduction shaft lever and interlocks the outlet pipe to rotate on the casing. The sprayer is installed in a casing, the casing is provided with an external water source access passage for connecting the inlet pipe sprayer, and the casing is also provided with an outlet pipe through-outlet for passing through the outlet pipe of the sprayer. The outlet pipe after passing through the casing is connected to a spray head set, and the lower part of the casing is provided with a discharge outlet. The present utility model not only improves the overall spraying effect that the water mist after spraying the turntable is accumulated to form the water drips, and also it can be recycled.

The washing nozzle for washing an inside of the machine tool with fluid includes a base portion having a tubular passage inside thereof, a supply port through the tubular passage, and a rotary member rotatable about an axis parallel to a surface on which the base portion is mounted, the rotary member having inside thereof a nozzle jet port and a nozzle flow passage allowing communication between the tubular passage and the nozzle jet port, wherein the jet port is formed so that fluid jetted from the jet port of the rotary member hits the surface on which the base portion is mounted and the jet of the fluid causes the rotary member to rotate about the parallel axis.

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.

A sprinkler assembly with a nutating distribution plate can improve even distribution of water. The distribution plate can tilt and/or translate upon water impinging the distribution plate to disperse water in different directions. The sprinkler assembly can have a deflector assembly including the distribution plate, a stem supported by a bearing, and a contact portion upstream of the distribution plate to contact an outer race that limits a range of movement of the distribution plate. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing.
