| 20100243762 | Irrigation Nozzle With Hydrofoil - A sprinkler nozzle is described, having a hydrofoil member located on a lower surface near the nozzle exit aperture. As the water exits the nozzle, a portion of that water moves over the hydrofoil, causing it to be gently directed downwards with minimal turbulence. A portion of this water may be further directed by ramps extending from the face of the nozzle. Ultimately, the water is distributed to close-in areas of turf at about the same rate as other distances in the watering radius, eliminating “close-in” overwater that occurs in prior art nozzles. Additionally, by providing a less abrupt flow-directing feature than the prior art, the rate and therefore the force of the nearby watering flow is less (i.e., more gentle) than prior art nozzles. | 09-30-2010 |
| 20100065663 | Fuel-Injector Nozzle - A nozzle for a fuel injector, in particular for a gas-turbine engine, is provided comprising a planar conductive electrode with a sharp edge forming an aperture, an upper insulation layer above the electrode and a lower insulation layer below the electrode, both insulation layers having apertures, and a swirler arrangement for creating a swirling action in liquid fuel introduced into the nozzle. The axis of swirl is generally perpendicular to the plane of the electrode. In use, the swirling fuel passes through the aperture of the lower insulation layer, the aperture of the conductive electrode and the aperture of the upper insulation layer. As the fuel passes through the aperture of the electrode, the electrode charges the swirling fuel, so that the nozzle supplies charged droplets of atomised fuel from an outlet orifice. The swirler arrangement may be a radial or axial swirler arrangement. | 03-18-2010 |
| 20080265063 | SPRAY NOZZLE - A spray nozzle for directing a fluid into a desired uniform spray pattern is disclosed that includes a nozzle body, a spray plate and a deflector plate.

| 20110253809 | PRESSURE SWIRL ATOMIZER WITH SWIRL-ASSISTING CONFIGURATION - A pressure swirl atomizer has a swirl chamber with an exit orifice and a plurality of tangential swirl channels disposed around the circumference of the swirl chamber. A pintle bearing surrounds a pintle. The pintle has a body portion and a nose portion that is narrower than the body portion. The nose portion has a tip that opens and closes the exit orifice and a side that is movable in the pintle bearing. In one embodiment, a return path formed between the nose portion of the pintle and the pintle bearing drains fluid from the swirl chamber when the exit orifice is closed. The nose portion positions the return path closer to a centerline of the atomizer, forcing fluid to swirl in the swirl chamber before draining. Since the fluid does not remain static in the chamber, less energy is needed to increase the fluid velocity and quickly form a desired spray pattern when the exit orifice is opened. | 10-20-2011 |
| 20110253808 | PRESSURE SWIRL ATOMIZER WITH REDUCED VOLUME SWIRL CHAMBER - A pressure swirl atomizer includes a swirl chamber having an exit orifice, a first section with a first volume, and a second section with a second volume. The second volume is smaller than the first volume, and the exit orifice disposed in the second section. The atomizer also includes a pintle movable to open and close the exit orifice and a plurality of tangential swirl channels disposed about a circumference of the swirl chamber. The reduced volume of the second section reduces the amount of static fluid to be accelerated into a flow pattern, thereby improving spray quality when the exit orifice is initially opened. | 10-20-2011 |
| 20110253807 | PRESSURE SWIRL ATOMIZER WITH CLOSURE ASSIST - A pressure swirl atomizer includes a nozzle having an exit orifice and a plurality of tangential swirl channels and a pintle that is movable within a pintle bearing between a closed position that closes the exit orifice and an open position that opens the exit orifice. The atomizer also has a pole piece having a channel, and the pole piece and the pintle are separated by an air gap when the pintle is in the closed position. A space between the pintle and the pintle bearing, the air gap, and the channel together form at least a part of a return path. Fluid from the tangential swirl channels drains through the return path when the pintle is in the closed position. To open the atomizer, a solenoid generates a magnetic force when energized, attracting the pintle toward the pole piece into the open position. A check valve disposed in the return path generates a fluid back pressure when the solenoid is de-energized to push the pintle toward the closed position. The fluid back pressure helps prevent the pintle from getting stuck in the open position. | 10-20-2011 |
| 20120205467 | Irrigation Sprinkler With Adjustable Nozzle Trajectory - One embodiment provides an asymmetrical nozzle housing within a nozzle base of a sprinkler which, when rotated, changes its angular orientation relative to the nozzle base. Since the nozzle is disposed within the nozzle housing, it similarly changes angular orientation relative to the nozzle base, thereby modifying the trajectory of ejected water during irrigation. In this respect, a user can change the trajectory of a watering stream by simply rotating the nozzle housing. | 08-16-2012 |
| 20110215176 | Fuel injector having a body with asymmetric spray-shaping surface - A fuel injector body has a fuel chamber and a valve seat around a fuel outlet. A valve body is positioned at the valve seat and a valve stem extends through the fuel outlet and fuel chamber. Engagement (disengagement) of valve body and valve seat closes (opens) the injector. The fuel chamber can comprise primary and secondary chambers connected by a valve passage and a metering member that restricts fuel flow between the chambers, thereby providing a flow-dependent closing force that reduces the dependence of fuel flow through the injector on fuel inlet pressure and that makes that flow dependent on an injector actuating force. The injector body or the valve body can comprise a spray-shaping surface arranged at least partly around the valve seat, which spray-shaping surface is arranged to direct a spray of fuel flowing through the fuel outlet. | 09-08-2011 |
| 20120305670 | SYSTEM FOR CONDITIONING FLOW THROUGH A COMBUSTOR - A system for conditioning flow through a combustor includes a nozzle, and a shroud circumferentially surrounds at least a portion of the nozzle. The shroud defines an upstream opening, and a plurality of vanes extends radially inward from the shroud. A circumferential slot extends through the shroud between the upstream opening and the plurality of vanes. | 12-06-2012 |
| 20100038455 | LIQUID EJECTOR - An ejector, which finds particular application as a fuel injector for a gas turbine engine, has an axially located passage ending as a nozzle having an internal surface facing radially inwardly towards the axis and which extends as an outboard cone about the axis of the passage and which terminates at a tip.

The outer surface of the ejector has a profile for accelerating a gaseous flow over the outer surface. Atomisation of fuel is improved along with relight capability, flame extinction and smoke production. | 02-18-2010 |
| 20110089264 | Radially outward flowing air-blast fuel injection for gas turbine engine - An air-blast fuel injector is disclosed which includes an outer air circuit having an exit portion, an inner air circuit having an outlet configured to direct air toward the exit portion of the outer air circuit, and a fuel circuit radially outboard of the inner air circuit and having an exit communicating with the outer air circuit upstream from the exit portion of the outer air circuit. | 04-21-2011 |
| 20120132727 | Dual Trajectory Nozzle for Rotor-Type Sprinkler - A sprinkler includes a turbine, a gear drive, a nozzle turret, and a nozzle that is installed in the turret. The gear drive rotatably couples the turbine and the nozzle. The nozzle has an exit angle which is different from its entry angle to change the trajectory of the water as it passes through the nozzle. The nozzle can be installed in an orientation to increase the trajectory of the water leaving the sprinkler, or installed in an orientation to decrease the trajectory of the water leaving the sprinkler. | 05-31-2012 |
| 20100327083 | ROTARY DRIVE SPRINKLER WITH FLOW CONTROL AND SHUT OFF VALVE IN NOZZLE HOUSING - A flow shut off or throttling valve is provided in a sprinkler nozzle housing to enable a nozzle to be changed without having to turn off a flow pressure source. The valve intersects a flow path through the nozzle housing and has an opening such that when the opening is aligned with the flow path, a flow stream can flow unobstructed through the flow path. The valve is movable between a fully open position in which the opening is aligned with the flow path and a closed position which blocks the flow stream from flowing to a nozzle disposed at an outlet passage of the flow path. The valve may be constructed to be either slidable or rotatable between the two positions, and is actuated by a gearing arrangement which is operable at the exterior of the nozzle housing. The external valve actuator may function as a physical barrier to retain the removable nozzle in the nozzle housing when the valve is open and to disengage the nozzle when the valve is closed. | 12-30-2010 |
