Abstract
An augmentation amplifier is provided for aspirating gas flow from a surrounding medium. The amplifier connects at an inlet to a pressurized gas source and at an outlet to a gas receiver. Ambient gas from the medium supplements source provided compressed gas. The amplifier includes a Venturi conduit including a throat, an external cavity and a diffusion chamber. The conduit receives and flows pressurized gas from the inlet to the throat. The cavity receives ambient gas from the medium. The chamber expands and accelerates the pressurized gas from the throat to entrain the ambient gas via aspiration. The accelerated and ambient gases combine into an exhaust gas to the outlet.
