Abstract: A spray head for a fluid dispenser device, including a hollow body having a substantially cylindrical sleeve and extending along a longitudinal axis (A), a substantially radial end wall provided with a spray orifice; and a spray profile upstream from the spray orifice. The spray profile includes at least one channel that is non-radial and/or non-axial relative to the longitudinal axis (A). The head, the spray orifice, and the spray profile are made as a single piece, the spray profile including a central pin, the internal end of the central pin, arranged inside the hollow body, being of shape that is conical or frustoconical, so as to guide the fluid towards the at least one non-radial and/or non-axial channel, the internal end forming an outlet valve.

Abstract: A variable arc sprinkler nozzle is provided for distribution of water through nearly any adjustable arcuate span. The nozzle includes one or more arcuate slots formed by the helical engagement of spiral surfaces of a deflector and a nozzle body. A user may rotate a portion of the nozzle body to select the arcuate span of the one or more slots. A matched precipitation rate feature is adjustable to proportion the amount of water directed to the deflector depending on the extent of the arcuate span. Further, edge fins on the deflector and nozzle body channel water flow at the two edges of the distribution arc to increase the throw radius and to provide fairly uniform water distribution at the edges of the arc.

Abstract: A fluid spray head comprising an expulsion channel (5) provided with a spray orifice (1) and a spray profile (10) formed in an end wall of said spray head, said spray profile (10) comprising preferably non-radial spray channels (11) opening out to a central spray chamber (12) disposed directly upstream from said spray orifice (1), an insert (20) being disposed in said expulsion channel (5) so as to form a cover for said spray profile (10), the central axis (X) of said insert (20) being substantially identical to the central axis (Y) of said expulsion channel (5), and said spray head including centering means for centering said insert (20).

Abstract: A rotary sprinkler comprising a sprinkler body supporting a nozzle body and a water distribution plate supported on a shaft downstream of said nozzle body, said water distribution plate provided with a plurality of grooves shaped to redirect a stream emitted from said nozzle body and to cause the water distribution plate to rotate when struck by the stream; a stream deflector supported within said sprinkler body and surrounding said nozzle body; wherein said nozzle body and said stream deflector cooperate to produce a substantially rectangular wetted pattern area.

Abstract: A processing apparatus for fluid with a simple structure, high productivity, ability of precise dispersion, emulsification and grinding, is provided. The apparatus of the present invention comprises at least two processing faces of a first face and a second face, both of which are arranged in a tight-closed passage and positioned opposite to each other to constitute part of said passage, and a contact pressure applying mechanism for putting both faces 1, 2 into closed contact with each other, wherein the rotation of the second processing face 2 in respect of the first processing face 1 may cause dispersion or emulsification of the fluid to be processed between both processing faces 1, 2.

Abstract: The nozzle of the present invention has an internal chamber, condiment input and discharge ports in fluid communication with the internal chamber, and an extension downstream of the condiment discharge port. Preferably, the internal chamber has a flow disrupter taking the form of a funnel-shaped end portion adjacent to the condiment discharge port. The internal chamber is preferably elongated and has a larger cross section than the spout to which the nozzle is connected to reduce condiment pressure and flow speed entering the nozzle. Condiment pressure can also be reduced in the internal chamber by other types of flow disrupters: protrusions extending from the internal chamber walls into the condiment flow and/or by an insert received within the internal chamber. At the funnel-shaped end portion, condiment flow adjacent to the internal chamber side walls is preferably diverted toward the discharge port to generate crossflow and turbulence, further reducing condiment pressure and force.

Abstract: The present invention provides a GDI injector of a vehicle engine that can change the level of swirl motion and make it possible to increase engine output and fuel mileage, comprising a nozzle body having an opening along its longitudinal axis, a fuel inlet member, a cylindrically-shaped needle valve being centrally located within the opening of the nozzle body, and a swirl generator, the swirl generator comprising: an inner case having a cylindrically-shaped body and a plurality of equally and angularly spaced lobes, the inner case being coupled to the needle; an outer case having a cylindrically-shaped body and a plurality of equally and angularly spaced grooves, the outer case being fixedly attached to the nozzle body; and an inner case rotator.

Abstract: A rotating stream sprinkler including a rotor plate supported on one end of a shaft for rotation, in an operative mode, relative to the shaft; a nozzle located along the shaft upstream of the rotor plate; the rotor plate formed with a chamber and one end of the shaft has a stator fixed thereto within the chamber, the fluid chamber at least partially filled with a viscous fluid; and wherein the chamber is at least partially closed at an upper end thereof by a rotor cap plate; and further wherein an underside of the rotor cap plate is provided with a first plurality of teeth and an upper surface of the stator is provided with a second plurality of mating teeth adapted to engage the first plurality of teeth to enable rotation of the rotor plate with the shaft in the adjustment mode.

Abstract: A sink rinsing device including an accelerating nozzle attached by a flexible stem to a fitting which fits onto a sink faucet above the aerator thereof. When not in use, the stem and nozzle lie flat against the underside of the faucet, out of the path of the water emerging from the faucet. When it is desired to rinse the sink, the stem is bent to bring the nozzle underneath the aerator of the faucet. The nozzle is removably fastenable to the fitting to secure the device in this position. Water emerging from the aerator of the faucet can now enter the inlet side of the nozzle, which directs a forceful stream of water against the sides of the sink. The fitting allows the nozzle to be rotated 360 degrees.
