Title
(EN) TWO-STEP DE-ICING NOZZLE
(FR) BUSE DE DÉGIVRAGE EN DEUX ÉTAPES
Abstract
(EN)
A nozzle for a spray gun comprises a fixed assembly and a displaceable assembly; the fixed assembly comprising a tubular nozzle housing (1) having an inlet end (2) connectable to a fluid supply, and having an outlet end (3) and a flow passage extending from the inlet end (2) to the outlet end (3), the displaceable assembly comprising a pressure regulating mechanism arranged in said flow passage at the outlet end (3) in order to control the nozzle pressure Said mechanism comprises a stem (6); a baffle (7) mounted for axial displacement on said stem (6) in said flow passage defining a nozzle gap (20) between said baffle (7) and the housing (1). The fixed assembly further comprises means (12) to distribute a passing fluid flow and to support a second end (6b) of the stem and the means are fixed inside the housing (1 ), said means (12) further being adapted to fixedly receive a valve cone (5) connectable to an axially displaceable fluid supply tube (8) for supplying a fluid. First biasing means (10) adjust the maximum baffle displacement at a first flow rate interval and second biasing means (14) supplement said first biasing means (10) at a second flow rate interval, counteracting additional fluid pressure on the baffle (7).
(FR)
L'invention porte sur une buse pour un pistolet de pulvérisation, laquelle buse comprend un ensemble fixe et un ensemble apte à être déplacé ; l'ensemble fixe comprend un boîtier de buse tubulaire (1) ayant une extrémité d'entrée (2) apte à être reliée à une alimentation en fluide, et ayant une extrémité de sortie (3) et un passage d'écoulement s'étendant de l'extrémité d'entrée (2) à l'extrémité de sortie (3), l'ensemble apte à être déplacé comprenant un mécanisme de régulation de pression disposé dans ledit passage d'écoulement à l'extrémité de sortie (3) afin de commander la pression de buse. Ledit mécanisme comprend une tige (6) ; un déflecteur (7) monté pour un déplacement axial sur ladite tige (6) dans ledit passage d'écoulement, définissant un espace de buse (20) entre ledit déflecteur (7) et le boîtier (1). L'ensemble fixe comprend de plus des moyens (12) pour distribuer un écoulement de fluide de passage et pour supporter une seconde extrémité (6b) de la tige, et les moyens sont fixés à l'intérieur du boîtier (1), lesdits moyens (12) étant de plus aptes à recevoir de façon fixe un cône de soupape (5) apte à être relié à un tube d'alimentation en fluide apte à être déplacé axialement (8) pour délivrer un fluide. Des premiers moyens de sollicitation (10) règlent le déplacement de déflecteur maximal à un premier intervalle de débit et des seconds moyens de sollicitation (14) complètent lesdits premiers moyens de sollicitation (10) à un second intervalle de débit, contrecarrant une pression de fluide additionnelle sur le déflecteur (7).
