Abstract
Official abstract text for this publication.
A manual compressed-air spraying device comprising a head in which are fixed an air nozzle forming a venturi and an output nozzle is disclosed. The head delimits, between the venturi and the output nozzle, a mixing chamber into which directly opens a conduit for channelling product to be sprayed. The output nozzle presents a convergent section and a divergent section downstream of the convergent section.
