Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An aspirator barrel of an aspirator system, the aspirator barrel comprising: connected inflation chambers wrapping around a circumference of the aspirator barrel and arranged along a length of the aspirator barrel, the connected inflation chambers connected to a showerhead nozzle configured to direct high-pressure gas to the connected inflation chambers such that the aspirator barrel is inflated; an aspirator barrel chamber for guiding atmospheric gas from a first end of the aspirator barrel to a second end, the aspirator barrel chamber defined by the aspirator barrel in response to the aspirator barrel being inflated; and a relief valve configured to release high-pressure gas into the aspirator barrel chamber when a pressure inside the connected inflation chambers exceeds a threshold pressure. 2. The aspirator barrel of claim 1 , wherein the aspirator barrel is made of a flexible fabric. 3. The aspirator barrel of claim 1 , wherein the showerhead nozzle is connected to the connected inflation chambers at a single point. 4. The aspirator barrel of claim 1 , wherein the showerhead nozzle is connected to the connected inflation chambers at a plurality of points. 5. The aspirator barrel of claim 1 , wherein the aspirator barrel is generally cylindrically shaped. 6. The aspirator barrel of claim 1 , wherein a diameter of the aspirator barrel at the first end is smaller than a diameter of the aspirator barrel at the second end.
