Abstract

A venturi-style vacuum-boosting hose attachment includes a single and unitary body having a centrally registered longitudinal axis, a primary inlet located at a proximal end of the body and having a first venturi passageway, a secondary bell-mouth inlet contiguous with the primary centrally disposed inlet and having a second venturi passageway, and a tail cone contiguous with the secondary inlet and having a third passageway terminating at an outlet located at a distal end of the body. The secondary inlet is configured to feed smooth air through the throat to the tail cone with increased velocity and egress via the outlet. The first venturi passageway, the second venturi passageway, and the tail cone are configured to modify a high-volume, low vacuum airflow source into a low-volume, high-vacuum airflow upstream of the primary inlet.
