Abstract: A liquid spray module which can be individually used, or which can be easily mounted in ganged side-by-side relation with a plurality of such modules. Each module includes a spray gun cartridge having liquid passages through the liquid to be sprayed, is directed and one or more air passages through which pressurized air may be directed for assisting in atomization of the liquid and controlling operating movement of a valve needle. Each spray gun cartridge further includes a manifold body having a central bore into which the spray gun cartridge is removably mounted and liquid and air inlet and outlet passages which communicate with the liquid and air spray gun cartridge passages. The spray gun cartridge is removable from the manifold body without disconnection of fluid supply lines to the manifold body and without removal of the manifold body from a ganged mounted array of such spray modules.

Abstract: A method and apparatus for producing man-made snow without using either compressed air or high-speed fans. The method makes use of a special water nozzle that is designed to provide a high volume spray of water particles that, owing to their size distribution (having a median size of between about 100 and 200 microns) in the spray, are readily susceptible to conversion to ice crystals as they settle to earth under favorable ambient conditions. Preferably, water applied to the nozzle is seeded with artificial nucleation sites so that water particles in a spray containing such sites are more susceptible to conversion to ice crystals as the particles settle to earth.

Abstract: A method for producing a mist in a spray head (1), especially for fire-fighting purposes or for humidification of intake air, in which method a medium, preferably an extinguishing medium, is supplied under pressure into the chamber (2) of the spray head via an inlet (3) and through at least one first channel (4) into at least one nozzle (5), which comprises at least one channel zone (6) narrower in a direction transverse to the flow of medium and after that in the direction of flow of medium a channel space (7) wider in a direction transverse to the flow of medium than the narrow channel zone, from which wider channel space the mist of medium generated is passed out of the spray head via an outlet orifice (8). The mist of medium is influenced, at least by increasing its momentum and/or reducing its droplet size, by supplying into the channel space (7) at least one second medium, preferably a gas.

Abstract: In a cleaning nozzle, a trumpet-shaped portion made up of multiple inclined portions or a curved portion is formed upstream of a minimum diameter portion of an ejection nozzle portion of a converging-diverging shape, and a gas ejection port is opened to an intermediate part of the trumpet-shaped portion. Inside the gas ejection port is formed a cleaning liquid ejection port. A gas is ejected at a higher speed than that of a cleaning liquid from the cleaning liquid ejection port to transform the cleaning liquid into droplets, which are further accelerated by a tapered portion formed downstream of the minimum diameter portion before being ejected. A small amount of liquid may be supplied to a pressurized gas passage between a powder injection portion and the cleaning nozzle to prevent a possible clogging of passage due to powder.

Abstract: The invention relates to a nozzle system for a delivery device for liquids, wherein the nozzle system comprises a nozzle and a device which fixes the nozzle in the delivery device. The delivery device, an atomiser, has a liquid reservoir from which a liquid is forced through the nozzle under pressure. The nozzle fixing means may itself be secured by a second fixing, e.g., in the form of a check nut, or the fixing may itself be a check nut. According to the invention the fixing means on the nozzle outlet side has a specific geometry which minimises the proportion of dispensed liquid deposited on the fixing means. Preferably, the present invention is part of a propellant-free device for nebulising pharmaceutical liquids.

Abstract: A twin fluid centrifugal nozzle for a spray dryer comprises a holder (10) having an annular cavity (11) which holds a sealing ring (12). Above the sealing ring (12) is a large annular recess (13) and an annular passage (14) of slightly increased diameter. The large annular recess (13) seats an orifice disc (16). A vortex chamber block (17) and a twin fluid feed block (18), which are constructed as one piece, are located in the large passage (14). The twin fluid feed block (18) has a passage (19) for air or steam, and a fluid passage (20) for liquid. The orifice disc (16) is a release mechanism for the swirling liquid, in the form of a round disc with apertures therein, through which liquid discharges to form a spray. The swirl or vortex chamber (23) has cyclone shape. One or more atomised liquid inlet passage(s) (24) extend to the vortex chamber (23) in a substantially tangential entry relative to the generally circular cross-section of the chamber (23). Air or steam enters the tangential inlet passage (24), from the passage (19), at a point (26), which is outermost or peripheral, relative to the axis of swirl chamber (23). The liquid flows through the passage (20), and enters the tangential entry passage (24) at a liquid entry point (25), which is located at the venturi point (27) of the tangential entry (24). The liquid enters (25) the stream of air or steam at an angle to the stream, and is pre-atomised in the stream. This pre-atomisation increases the swirl velocity of the liquid in the vortex chamber (23), imparting a higher centrifugal force to liquid droplets emerging from the orifice disc (16).

Abstract: A high efficiency liquid fuel atomizer includes an elongated generally tubular member defining a liquid fuel pre-atomization chamber. The tubular member has an outer wall that extends around the chamber, an upstream end adapted for connection to a source of liquid fuel and a downstream fuel delivery outlet. The atomizer also includes a larger diameter outer tube that is concentric to the tubular member and defines a generally annular pressurized atomizing fluid supply conduit disposed in surrounding relationship relative to the chamber. The outer tube has an inlet adapted for connection to a source of pressurized atomizing fluid and a downstream pressurized atomizing fluid delivery outlet. One or more orifices are provided in the outer wall of the tubular member so as to intercommunicate the chamber and the annular conduit to permit pressurized atomizing fluid to enter the chamber and at least partially atomize the fluid fuel therein. Also disclosed is an atomizing tip which includes a novel y-shaped for further atomizing the liquid fuel.
