Abstract (en)
[origin: WO8101668A1] A blowing tool comprises a body part with a connection (8) for pressurized, gaseous fluid, an exhaust nozzle (13) and a valve (9, 10) located between said connection and said nozzle and having an adjustable fluid passage. The nozzle is provided with a plurality of exhaust channels (12) ending near or in the mantle surface of said nozzle and spaced from the central parts of said nozzle. The location of the outlet apertures brings co-ejected air to effectively reduce differences in pressure and velocity between the ambient air and the exhausted gas so that a pronounced lowering of the noise level of the working blowing tool can be obtained.
Abstract (fr)
Un outil de soufflage comprend un corps avec une connexion (8) pour un fluide gazeux sous pression, un ajutage de sortie (13) et une soupape (9, 10) situee entre la connexion et l'ajutage et ayant un passage de fluide reglable. L'ajutage est pourvu d'une pluralite de canaux de sortie (12) se terminant a proximite ou dans la surface de l'enveloppe exterieure de l'ajutage et espaces des parties centrales de l'ajutage. Le positionnement des ouvertures de sortie amene l'air ejecte de maniere combinee a reduire de maniere effective les differences de pression et de vitesse entre l'air ambiant et les gaz refoules de telle sorte qu'un abaissement sensible du niveau sonore de l'outil de soufflage de travail soit obtenu.
