The fuel injector has a first means defining a number of flowpaths each having an inlet for receiving air and an outlet for discharging a fuel/air mixture. One or more arrays of vanes are each positioned to impart swirl to an associated one or more of the flowpaths. Second means are provided for introducing the fuel to the air.

A nozzle for the application of a fluid to a passing substrate in a bead form. The nozzle has a portion of the nozzle tip removed, preferably an anterior or aft portion, such that an even bead of a preselected depth may be applied to a workpiece to provide a reliable sealing joint

A nozzle (1) for use in coating a web-like material by means of high-pressure spraying techniques is manufactured by forming a piece having a tapered duct ending in a closed tip, with a transverse V-shaped groove (3) subsequently machined in the tip. The angle of the V-shaped groove (3) is in the range from 25 to 50.degree., such as 35 to 45.degree..

A nozzle 10 which receives first and second materials 24, 30 and which has an outlet aperture 18. The first material 24 is received within the outlet aperture 18 and is atomized by the second material 30 within the outlet aperture 18 before it is emitted from the nozzle 10 and applied to a targeted location and/or object 26.

A nozzle 10 having a material outlet aperture 24 which causes received material 28 to be emitted in the form of a streaming sheet 30.

The present invention provides a nozzle for teeming molten metal, particularly molten steel, from a tundish or other receptacle, which nozzle comprises an inlet, an outlet, and inner and outer tubular members which define a bore through the nozzle between the inlet and outlet. The nozzle is characterised in that both of said inner and outer tubular members are constructed from refractory materials, and in that the inner member extends within the outer member to the inlet. The inner and outer cer...

An air nozzle is provided which produces high thrust with low noise. The nozzle is adapted to provide flow amplification by inducing flow of ambient air with high pressure air.

A fuel injector has a number of groups of nozzles. The groups are generally concentric with an injector axis. Each nozzle defines a gas flowpath having an outlet for discharging a fuel/air mixture jet. There are means for introducing the fuel to the air. One or more groups of the nozzles are oriented to direct the associated jets skew to the injector axis.

A nozzle 10 having an outlet aperture 26, the outlet aperture 26 having at least one injector 40,42 which is disposed within the aperture 26 and which injects a material 17 within the aperture 26, effective to allow the material to be atomized and to be emitted from the aperture 26 at a substantially identical velocity at each point within the aperture 26.

The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a he...
