Abstract
A Venturi device has a body defining a motive section and a discharge section converging toward and spaced a distance apart to define a Venturi gap, defining a first suction port and a second suction port each in fluid communication with the Venturi gap, and defining a chamber having an outlet end of the motive section and an inlet end of the discharge section dividing the chamber into a first portion and a second portion in fluid communication with one another above and below the inlet and outlet ends and through the Venturi gap. The first and second portions both have a plurality of spaced apart fingers protruding radially and axially from an inner wall thereof. A suction housing is sealingly connected to the chamber and collectively defines a check valve with the body, and a cap is sealing connected to close another end of the chamber.
