<p>A device for shaping a vacuum includes a housing (12) having a primary passageway (14) which includes an inlet (16). A fluid shaping mechanism (20) is disposed in the primary passageway in fluid communication with the inlet for changing the shape of a fluid flow into a planar fluid flow flowing radially outwardly from a central point (22). The fluid shaping mechanism includes a conically-shaped portion (36) disposed within the primary passageway, a plurality of secondary passageways (30) extending through the housing from a periphery of the cone-shaped surface to outlets at a bottom surface of the housing, and a reflector (50) adjacent to and spaced from the bottom surface for uniformly reflecting the fluid from the secondary passageways radially outwardly to create a vacuum adjacent thereto. <IMAGE></p> |
