ABSTRACT:
An improved venturi apparatus for the incorporation of air into a liquid. The preferred embodiment of the invention comprises a funnel section, a cylindrical section, and a frusto-conical section. Lateral tubes extend from the cylindrical section so as to form an acute angle relative to the central axis of the cylindrical section, thereby preventing leakage of liquid out through the lateral tubes during use and subsequent handling.
