Patent
CA 2520806
The invention relates to a pneumatic suction device (1) comprising a main nozzle (10), through which the expansion of a compressed gas is designed to generate, by means of a reaction, suction with a given depression and flow rate. The invention is characterised in that it also comprises at least one secondary nozzle (20), through which the expansion of the compressed gas is designed to generate, by means of a reaction, suction with a lower flow rate and a higher depression than those obtained with the main nozzle (10). The invention is further characterised in that each secondary nozzle (20) is mounted to move between a passive position, in which the effective expansion of the compressed gas is performed by the main nozzle (10), and an active position, in which the effective expansion of the compressed gas is performed by the secondary nozzle (20).
Dispositif d'aspiration pneumatique (1) comportant une tuyère (10), dite principale, à travers laquelle la détente d'un gaz comprimé est apte à générer par réaction une aspiration de débit et de dépression donnée, caractérisé en ce qu'il comporte, en outre, au moins une tuyère secondaire (20) à travers laquelle la détente du gaz comprimé est apte à générer par réaction une aspiration d'un débit inférieur et d'une dépression supérieure respectivement au débit et à la dépression obtenue avec la tuyère principale (10), et en ce que chaque tuyère secondaire (20) est montée mobile en déplacement entre une position passive, dans laquelle la détente effective du gaz comprimé est opérée par la tuyère principale (10), et une position active, dans laquelle la détente effective du gaz comprimé est opérée par ladite tuyère secondaire (20).
