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 sensor-cleaning apparatus includes an upper piece, a lower piece fixed to the upper piece, a plurality of inserts inserted into the upper piece, and a plurality of nozzles. The upper piece and the lower piece form a tubular segment that is elongated along an arc of circle and encloses a chamber. Each nozzle is formed of the upper piece and one of the inserts. Each nozzle includes a deflection surface and a tunnel from the chamber to the deflection surface, and each tunnel is partially formed of the upper piece and partially formed of the respective insert.

The helicopter drizzle pipe allows for aerial wildfire suppression efforts in otherwise inaccessible areas. The pipe is balanced between the bottom legs of the helicopter as to prevent an imbalance or obstruction to the helicopter rotor blades. Along the bottom of the pipe are strategically placed holes to allow the liquid in the pipe to drizzle out at a constant speed over the whole length of the pipe, simulating rainfall. Due to the pipe's positioning, it is also very easy to remove from the helicopter for refilling or cleaning. Furthermore, the method by which the liquid drizzles from the pipe does not necessitate aircraft movement, thus functioning even when the helicopter hovers to thoroughly cover a specific area.

A nozzle includes a shell, a distributor, a panel and a collar. The distributor is inserted in the shell. The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.

A denuder, such as a bone stock denuder container, is disclosed. The denuder includes a nozzle and a container body. The nozzle is configured to be fluidically coupled to a source of fluid and to direct a fluid stream. The container body includes curved chamber wall that forms a wash chamber. The wash chamber is configured to receive a bone stock. The nozzle is configured to direct the fluid stream to impact the curved chamber wall.

Silencing and separation in a cold-air, essential-oil, diffuser apparatus and method pass flow through a channel having comparatively high aspect ratios of length to thickness and width to thickness. Curved, tapered, non-parallel, and quasi random surfaces reduce probability and power of resonant frequencies. Offsetting flow through a channel is followed by impingement against an obstructing surface, redirection elsewhere within a drift (separation) chamber, and exiting through a smaller, and differently oriented exit port. Silencing is improved by changes of cross-sectional area creating high-pass and low pass acoustic filters, changes of direction, and absorption of acoustic energy in fluid-droplet-laden air.

Provided is a washer nozzle that since a plurality of stepped portions (stepped wall portions) formed in a stepped shape in a flow direction of the cleaning liquid are provided in a flow path between an inflow hole and a discharge port in a main body portion, it is possible to spread the cleaning liquid in a width direction of the flow path by causing the cleaning liquid flowing from an upstream side to collide with stepped surfaces of the plurality of stepped portions one after another. Therefore, even when a flow rate of the cleaning liquid is small, without increasing a discharge capacity of a washer pump, it is possible to disperse the cleaning liquid fully in the width direction of the flow path, and it is possible to uniformly discharge the cleaning liquid to substantially the entire surface of an imaging lens.

A nozzle with a random discharge jet pattern includes an intake cone having an upstream end, a downstream end, and an outer surface. The nozzle includes a bell with an upstream end, a downstream end, and an inner surface. The bell is fixed to the intake cone so that the upstream end of the bell encircles the downstream end of the intake cone. Vanes couple the bell to the intake cone, and the vanes extend from the outer surface of the intake cone to the inner surface of the bell and then along the inner surface of the bell toward the downstream end thereof. The vanes define a plurality of channels extending along the inner surface of the bell from the upstream end toward the downstream end thereof.

The present disclosure discloses a water outlet assembly and a water outlet assembly. The water outlet assembly comprises an ejector and a water outlet portion. The ejector and the water outlet portion are disposed along a water flow direction. The ejector comprises a jet hole. The water outlet portion comprises a shielding portion and a water outlet hole penetrating the shielding portion. An opening of the water outlet hole is enlarged along the water flow direction. Water ejected from the jet hole is divided into an impact portion and a straight portion, the impact portion impacts the shielding portion and flows out along an edge of the water outlet hole to define a water curtain, and the straight portion directly flows through the water outlet hole to be ejected to define straight water.

A sprinkler head nozzle assembly in accordance with an embodiment of the present invention includes an adjustable nozzle operable to extend and reduce an arcuate opening wherein the size of the arcuate opening indicates the arc of coverage of the sprinkler head nozzle assembly and a rotating distributor, mounted on a central shaft extending through the housing and the nozzle member, and operable to deflect a flow of water from the arcuate opening out of the nozzle assembly.
