Aspirator e.g. water filtration aspirator, for use in e.g. glass squeegee, has water-air separator for directing gas phase in suction chamber and liquid phase and particles in filtering reservoir in which liquid phase is preserved

摘要

The aspirator has a water-air separator (1) for directing a gas phase in a suction chamber (60) and a liquid phase and particles in a filtering reservoir (22) in which the liquid phase is preserved. The filtering reservoir has an annular shaped peripheral section (103) to carry out centrifugation of aspirated flow of air charged with particles and/or liquid before the flow enters into baffles. An inner partition (106) is separated from another inner partition at the baffles for creating venturi effect.
