Improvements in or relating to valve controlled nozzles

... 579,626. Valves. BLAW KNOX, Ltd., and CONACHER, J. E. June 9, 1944, No. 11110. [Class 135] A valve controlled nozzle for supplying a fluid under pressure, such as air or steam, to powdered or granular material, such as cement, comprises a nozzle 1 and a valve plunger 2 with an opening 3 through which the fluid can pass. The plunger 2 carries a resilient washer 4 adapted to seat on the surface 16 of the nozzle to close the outlet, when the supply of the fluid is cut off, under the tension of a dome or sleeve 8 of resilient material, such as rubber, which also serves to seal off the nozzle from ingress of the powdered material. An opening 9 in the sleeve 8 allows the passage of the fluid when the valve is open as shown.

A shower head

The shower head is composed of a spray head disposed at the forward end of a spray housing, a distributor disposed in the spray housing and having first and second supply openings, and a selector. By rotating the spray housing, the selector can be moved axially in the distributor. The shower head also has a first chamber disposed at the forward end of the distributor, a straight spray nozzle disposed at the forward end of the first chamber, and a needle valve. The needle valve can be slid in the first chamber and is composed of a needle and a circular plate resiliently urged to a closed position. Only when the selector pushes forward the circular plate to provide a straight spray does the straight spray nozzle communicate with the inside of the distributor. In other cases the distributor is closed by the circular plate so that the inside of the shower head is protected from dust or other foreign particles.

Dispensing apparatus

Water guns

A water gun comprises a barrel 1 having a neck 2 from which water is to be projected, valve means 4 for charging the barrel 1 with water from a tank 5, and means for ejecting the charge of water from the barrel as a single body, thereby obtaining the effect of a high pressure jet of short length. The projected body of water is of high density, that is it does not break up into a diffuse spray. The charge of water may be ejected by, for example, compressed air from a cylinder 8 connected by valve 9 and pipe 6 to the barrel 1, via a spring- loaded valve 3 on the end of the neck 2 which is forced open as the pressure of the water in the barrel rises. Other propellants may be used, e.g. explosive or mechanical, and the water (or other liquid) may alternatively be supplied in a sealed cartridge. <IMAGE>

NOZZLE FOR SPRAYING DEVICE

Cette Buse (2) pour dispositif de pulvérisation comprenant, à son extrémité distale, un pavillon (5) dont l'ouverture (51) comprend au moins une dent (54, 55, 56). Avantageusement, la présence de dent à l'ouverture de sortie de la buse ou de picots et/ou lames à l'intérieur de la buse tend à perturber l'écoulement du jet d'air. En cas de feuille formant écran au jet d'air, le jet d'air ainsi rendu turbulent, augmente ses chances de dévier la feuille écran et ainsi augmente la pénétration du traitement dans le feuillage. This nozzle (2) for a spraying device comprising, at its distal end, a horn (5), the opening (51) of which comprises at least one tooth (54, 55, 56). Advantageously, the presence of teeth at the outlet opening of the nozzle or of pins and / or blades inside the nozzle tends to disturb the flow of the air jet. In the case of a sheet forming a screen to the air jet, the air jet thus rendered turbulent increases its chances of deflecting the screen sheet and thus increases the penetration of the treatment into the foliage.

WASHING DEVICE INJECTION VALVE OF AN INTERNAL COMBUSTION ENGINE BOOSTER

Cabezal de pulverización para un aparato de granulación que comprende: una tobera ranurada (22), en la cual un canal de tobera (26) con sección de paso alargada, hacia abajo por una superficie de fondo (28), está limitado hacia arriba por una superficie superior (30) y lateralmente en cada caso por una superficie lateral (32, 34), en el que se extiende un cuerpo de regulación de paso (36) alargado en el canal de tobera (26) axialmente entre las dos superficies laterales (32, 34) para limitar una ranura de tobera en cuanto a la altura, y el cuerpo de regulación (36) se puede girar alrededor de un eje longitudinal para ajustar la altura de esta ranura de tobera; caracterizado porque el cuerpo de regulación (36) es un cuerpo cilíndrico con una sección transversal ovalada y un eje central, el cual está dispuesto aproximadamente en posición central entre la superficie de fondo (28) y la superficie superior (30) y que puede girar alrededor de su eje central (38), de tal manera que tanto por debajo como también por encima del cuerpo de regulación (36) está formada una ranura de tobera (42, 44), cuya altura se puede ajustar mediante el giro del cuerpo de regulación (36) alrededor de su eje central (38). Spray head for a granulation apparatus comprising: a slotted nozzle (22), in which a nozzle channel (26) with an elongated passage section, downwards by a bottom surface (28), is bounded upwards by an upper surface (30) and laterally in each case by a lateral surface (32, 34), in which an elongated passage regulating body (36) extends in the nozzle channel (26) axially between the two lateral surfaces (32, 34) to limit a nozzle groove in terms of height, and the regulating body (36) can be rotated about a longitudinal axis to adjust the height of this nozzle groove; characterized in that the regulating body (36) is a cylindrical body with an oval cross section and a central axis, which is arranged approximately centrally between the bottom surface (28) and the upper surface ...
