Abstract
A blowing device comprises a body part with a connection (8) for a pressurized, gaseous fluid, an exhaust nozzle (17) and a valve (11, 13) having an adjustable fluid passage located between said connection and said nozzle. The nozzle is provided with a plurality of exhaust channels (30) for said fluid and the through-flow area of the valve fluid passage is substantially larger than the sum of the through-flow areas of said exhaust channels thereby preventing the generation of harmful noise by said device while obtaining a strong blowing power. The exhaust channels are distributed substantially evenly in the circumferential direction of said nozzle (17) and the external mantle surface of the exhaust nozzle is formed so as to allow a substantial coejection of outside air by the fluid flow ejected from said nozzle.
