Abstract (en)

[origin: WO2007146882A1] Embodiments of the present invention relate generally to regenerative vacuum generators for use on aircraft or other transportation vehicles. Embodiments of the invention further relate to modified regenerative vacuum generators (20) that provide a larger area for air flow, as well as provide larger RPMs than typical regenerative vacuum generators. Further embodiments of the invention relate to modified regenerative vacuum generators (20) for use on aircraft or other transportation vehicles. These features help generate high flow and vacuum in less time, which ensure a good vacuum system, and allow the generators to be much smaller than generators currently used in these applications.
