Description

The present invention relates to a spray device which comprises a nozzle for ejecting a jet of fluid. According to the invention, the spray device comprises a nozzle holder (6; 6, 15, 16, 19) which is adapted to be gripped manually when using the spray device and which is movable relative to the nozzle essentially in parallel with the direction of the jet of fluid. The spray device further comprises a valve which is connected in front of the nozzle and is adapted to open when moving the nozzle holder in the direction of the jet of fluid relative to the nozzle. The nozzle is biased in the direction of the jet of fluid relative to the nozzle holder (6), and the relative position of the nozzle holder to the nozzle is affected by the reaction power of the jet of fluid.

La présente invention concerne un dispositif de pulvérisation qui comprend une buse pour éjecter un jet de fluide. Selon l'invention, le dispositif de pulvérisation comprend un porte-buse (6; 6, 15, 16, 19) conçu pour être saisi manuellement lors de l'utilisation du dispositif de pulvérisation et mobile par rapport à ladite buse de manière essentiellement parallèle à la direction du jet de fluide. Le dispositif de pulvérisation comprend, en outre, une soupape reliée devant la buse et conçue pour s'ouvrir lorsque le porte-buse est déplacé dans la direction du jet de fluide par rapport à la buse. La buse est forcée dans la direction du jet de fluide par rapport au porte-buse (6), et la position relative du porte-buse par rapport à la buse est modifiée par la puissance de réaction du jet de fluide.
