Abstract:
Ce système de production d'au moins un courant d'air de section transversale allongée composé de plusieurs flux d'air (F1, F2, F3, Fv, Fi) répartis le long de la section transversale du courant d'air comprend au moins un caisson (2) rigide allongé, qui s'étend en longueur suivant l'axe longitudinal de la section transversale du courant d'air et qui définit un volume interne (V2, V2') longitudinal à l'intérieur duquel circule de l'air sous pression, entre, d'une part, une entrée d'alimentation en air comprimé, et, d'autre part, des sorties (81, 81', 82, 82', 83, 83') et aptes à générer chacune un des flux d'air (F1, F2, F3). Lesdites sorties incluent, à la fois, des sorties latérales (83, 83') qui sont situées de part et d'autre d'un premier axe (X1) d'une section transversale du caisson (2) et des sorties centrales (81, 81', 82, 82') qui, dans une section transversale du caisson (2), sont situées, suivant la direction d'un second axe (X2) perpendiculaire au premier axe (X1), entre les sorties latérales (83, 83') et dont les flux d'air (F3) qu'elles génèrent sont laminaires. Les sorties latérales (83, 83') génèrent des flux d'air (F3) qui sont aptes à entrainer un flux d'air induit (Fi) extérieur au caisson (2) et qui longent une surface extérieure d'une portion (25, 25') du caisson (2).
Abstract:
A clog-resistant injector spray nozzle (200) allows relatively unobstrusive insertion through a small access aperture (120) into existing ductwork (110) in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle (200) comprises an easily cleaned and easily replaced straight liquid tube(365) whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube (365) until they both exit the injector (200), thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.
Abstract:
Zum Reinigen eines zur maschinellen Serienbeschichtung von Werkstücken dienenden Zerstäubers (1) in einem hierfür vorgesehenen Reinigungsgerät (10) wird das Außengehäuse des Zerstäubers (1) von Düsen des Reinigungsgeräts (10) besprüht, während gleichzeitig von dem Sprühkopf (3) des Zerstäubers (1) in einem Kurzspülvorgang abgesprühte Farb- und Spülmedien durch einen in dem Innenraum des Reinigungsgeräts (10) befindlichen Rohrkörper (30) aufgefangen und abgeführt werden. Bei elektrostatischen Zerstäubern (1) erfolgt zuvor eine Potenzialangleichung zwischen dem Zerstäuber (1) und dem Reinigungsgerät (10). Durch zusätzliche Maßnahmen wird erreicht, dass der Zerstäuber (1) von der dafür vorgesehenen Handhabungsmaschine nur aus einer richtigen Richtung zu dem Reinigungsgerät (10) bewegt werden kann.

Abstract:
A high-volume, low-pressure manual spray gun (10, 92, or 116) operates from a conventional high pressure compressor. The gun (10, 92, or 116) has a barrel (14) that supports a spray head (20), a handle (22) that extends downwardly from the barrel (14), an inlet port (24) at the bottom of the handle (22) for receiving compressed air, and a passage (26) in the handle (22) directing the compressed air toward the barrel (14). A venturi (68, 94, or 118) is mounted within the barrel (14) and discharges a stream of compressed air downstream toward the spray head (20). The venturi (68, 94, or 118) entrains ambient air through one or more orifices (76 or 130) in the barrel (14). An air valve (36) mounted within the handle (22) controls the flow of compressed air through the gun (10, 92, or 116). A liquid valve (38) controls discharge of liquid through a liquid jet (42) in the spray head (20). The air valve (36) and liquid valve (42) are operated with a common trigger (40). The venturi (68, 94, or 118) is entirely separate from the air valve (36) and liquid valve (38), and no linkage extends through the venturi (68, 94 or 118) to operate the air valve (36). The venturi (94 or 118) is preferably sealed to the passage in the handle (22) to receive all compressed air flows directly from the handle (22), permitting ambient air to be entrained from rearward of the barrel (14).

Abstract:
L'invention a pour objet un clapet de détendeur. Clapet de détendeur du type dont la section dudit clapet est triangulaire et inscrite dans un cercle, les trois génératrices du cercle font office de moyens de guidage du clapet dans son logement, caractérisé par le fait que la tête (8) est sphérique et que le corps (9) se prolonge par trois plats (10, 11, 12) identiques équidistants qui assurent un grand passage de l'air. Clapet de détendeur pour pistolet à peinture.
