# Pneumatic grip

## Abstract

A device for shaping a vacuum includes a housing having a primary passageway which includes an inlet. A fluid shaping mechanism 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. The fluid shaping mechanism includes a conically-shaped portion disposed within the primary passageway, a plurality of secondary passageways extending through the housing from a periphery of the cone-shaped surface to outlets at a bottom surface of the housing, and a reflector 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.
