Abstract:
A spray nozzle, which in some embodiments has a body and a deflector, the body having a fluid passageway and an outer wall including a plurality of fluid-flow orifices therethrough in fluid communication with the fluid passageway and spaced at least partly circumferentially around the outer wall, where the deflector is disposed at least partly circumferentially about and radially outwardly of the body in fluid communication with the plurality of fluid-flow orifices, and the body includes slots and fingers spaced at least partly circumferentially about the deflector. Some embodiments include a second deflector. In some embodiments, each finger and slot has a configuration that defines, at least in part, a flow trajectory, and the flow trajectory defined, at least in part, by one finger or slot is different from the flow trajectory defined by another finger or slot.
Abstract:
The invention relates to the field of inhalation methods and inhalation devices for liquids. In particular, the invention relates to an inhalation method using an inhalation device having a nebulizing nozzle (6), and to a method for the generation of an aerosol of an aqueous formulation comprising pirfenidone by means of such inhalation device.
Abstract:
A multi-cone, multi-stage spray nozzle includes a nozzle body (102), a valve stem (104) with a first valve head (128), and a second valve head (106) attached to the first valve head (128). The first valve stem (104) is biased into a closed position against a valve seat (120) of the nozzle body (102) by a bias device. The second valve head (106) is continuously open. Upon the application of a first fluid pressure, which is less than a threshold fluid pressure, the bias device (108) maintains the valve stem (104) in the closed position while the second valve head (106) is continuously open. And upon the application of a second fluid pressure, which is at least as great as the threshold fluid pressure, the valve stem (104) moves to an open position while the second valve head (106) remains continuously open.
Abstract:
A nucleation nozzle (1) for forming freezing nuclei for devices (100) for making artificial snow, starting from a jet of pressurised liquid, comprising a compressed air duct (2) having an inlet opening and an outlet opening. A first stretch (2a) of the compressed air duct (2) has a cross section which decreases in the flow direction (F) of the compressed air, from the inlet opening to the outlet opening (3). The first stretch (2a) is followed by a second stretch (2b) having a cross section which increases in the flow direction (F) of the compressed air from the inlet opening to the outlet opening (3). There is provided at least one water duct (4) having an inlet opening and an outlet opening (5). The water duct (4) is separate from the compressed air duct (2). The outlet opening (5) of the water duct (4) is positioned close to the outlet opening (3) of the compressed air duct (2).
Abstract:
Spray nozzle assembly (300) is configured to generate a swirled spray (312) with improved rotating velocity ω and smaller uniform droplet size. Cup-shaped nozzle member (300) has a body portion (318) with a cylindrical side wall (320) surrounding a central longitudinal spray axis (322), a circular closed end wall (324) and an exit aperture (310) coaxial with the spray axis (322) and defined through the end wall (324). A fluid dynamic circuit (330) is formed in an inner surface (326) of end wall (324) and includes three inwardly tapered power nozzles (302, 304, 306) terminating in an interaction region (308) which is exhausted via the exit aperture (310). The power nozzles have respective longitudinal axes (334, 362, 382) offset with respect to the spray axis (322) with corresponding non-tangential angles of attack (352, 374, 394) configured to efficiently cause a fluid vortex in interaction region (308).
Abstract:

Abstract:
본 고안은 가압이 편리한 펌프를 구비한 파운데이션 용기에 관한 것으로서, 더욱 상세하게는 펌프본체의 외벽이 안쪽으로 오목한 장구 형상으로 형성함으로써 펌핑 방법이 펌프상체의 중심부를 수직으로 가압해야 하는 것으로 제한되는 것이 아니라 펌프상체의 어느 부위를 가압하여도 용이하게 내용물이 배출되도록 하는 가압이 편리한 펌프를 구비한 파운데이션 용기에 관한 것이다. 또한, 펌프상체와 펌프본체를 일체로 형성하며, 배출밸브와 흡입밸브를 동일한 형상으로 형성하여 펌프 구조를 단순화시킴으로써 양산이 용이하여 생산성을 향상시키는 가압이 편리한 펌프를 구비한 파운데이션 용기에 관한 것이다.
