ABSTRACT:
A novel gas-powered aspirator comprises a venturi chamber for suctioning a vacuum jar incorporating a valve body, movable between two positions, one for directing gas to the venturi chamber, and the other for closing it from the gas supply. The valve body position is determined by the vacuum pressure in the jar.
