Pneumatic suction device for e.g. domestic cleaning, has secondary nozzle across which release of compressed gas generates lower suction rate and higher depression corresponding to suction rate and depression obtained with main nozzle

摘要

The device has a secondary nozzle (20) across which a release of a compressed gas generates a lower suction rate and a higher depression corresponding to a suction rate and depression obtained with a main nozzle (10). The nozzle (20) is mounted between a passive position in which release of compressed gas is operated by the main nozzle and an active position in which release of gas is operated by the nozzle (20).
