Abstract:
A suction pulsator for periodically generating a vacuum in a container, the pulsator comprising:a nozzle body defining a central nozzle hole connectable to a compressed air source;a nozzle jacket surrounding said nozzle body, an inside of said nozzle jacket and an outside of nozzle body define a suction gap substantially concentric with said central nozzle hole;a radial deflecting surface spaced from an end of said nozzle body and said nozzle jacket to define a radial outlet gap, said radial outlet gap being in communication with said central nozzle hole and said suction gap, said radial deflecting surface guiding air from said central nozzle hole over said suction gap;a suction connection opening in communication with said suction gap and spaced from said radial outlet gap;a suction line in communication with said suction connection opening.
