VENTURI-EFFECT SPRAYING DEVICE AND ITS USE IN COSMETOLOGY AND IN PERFUMERY

摘要

Manual compressed-air spraying device comprising a head (107) in which are fixed an air nozzle forming a venturi (118) and an output nozzle (132). The head delimits, between the venturi and the output nozzle, a mixing chamber (119) into which directly opens a conduit (15) for channelling product to be sprayed. The output nozzle presents a convergent section (120b) and a divergent section (120c) downstream of the convergent section.
