Collapsible inflatable aspirator system
First Claim
1. An aspirator system for inflating an inflatable evacuation device, the aspirator system comprising:
- an aspirator body having a plurality of flapper doors configured to open to allow intake of atmospheric gas;
an aspirator barrel connecting the aspirator body to the inflatable evacuation device, having connected inflation chambers wrapping around a circumference of the aspirator barrel and arranged along a length of the aspirator barrel, and being configured to provide an aspirator barrel chamber for guiding the atmospheric gas to the inflatable evacuation device in response to the aspirator barrel being inflated; and
a showerhead nozzle disposed within the aspirator body, connected to the connected inflation chambers, configured to direct a first portion of high-pressure gas to the connected inflation chambers to inflate the aspirator barrel, and configured to direct a second portion of high-pressure gas through the aspirator barrel and compel intake of atmospheric gas through the plurality of flapper doors, to inflate the inflatable evacuation device;
wherein the aspirator barrel comprises a relief valve configured to release gas into the aspirator barrel chamber in response to a pressure inside the connected inflation chambers exceeding a threshold pressure.

Abstract
An aspirator system for inflating an inflatable evacuation device includes an aspirator body having a plurality of flapper doors configured to open to allow intake of atmospheric gas. The aspirator system also includes an aspirator barrel connecting the aspirator body to the inflatable evacuation device, having connected inflation chambers wrapping around a circumference of the aspirator barrel and arranged along a length of the aspirator barrel, and being configured to provide an aspirator barrel chamber for guiding the atmospheric gas to the inflatable evacuation device when the aspirator barrel is inflated. The aspirator system also includes a showerhead nozzle connected to the connected inflation chambers, configured to direct high-pressure gas to inflate the aspirator barrel and compel intake of atmospheric gas through the plurality of flapper doors, to inflate the inflatable evacuation device.
