Abstract

An aspirator includes an aspirator body having at least one flapper door designed to allow gas intake from an environment of the aspirator. The aspirator also includes an aspirator barrel having an end tip, a compressible spring, and a fabric positioned about the compressible spring and designed to extend in response to receiving the gas and transfer the gas from the aspirator body to the inflatable flotation device. The aspirator also includes a gas valve designed to receive fluid from a source of compressed fluid. The aspirator also includes a nozzle located within the aspirator body, the nozzle is coupled to the gas valve, and is designed to receive the fluid through the gas valve and transfer the fluid to the gas valve. At least a portion of the gas is directed toward the aspirator canister such that the at least one baffle door allows the gas to flow from the environment into the aspirator canister.

Description

technical field [0001] The present disclosure relates to evacuation systems for aircraft, and more particularly to air extractors designed to provide air for inflating evacuation devices. Background technique [0002] Inflatable evacuation devices, such as aircraft evacuation slides and emergency lifeboats, typically include a source of compressed fluid, such as a gas cylinder, and an air extractor. The aspirator, which works with the inflation cylinder, mixes gas from the atmosphere with the fluid to provide gas to inflate the emergency evacuation device. Aspirators are often stored in limited packaging space, and therefore evacuation device packaging is often densely packed. The packaging process for emergency evacuation devices can be relatively difficult due to limited packaging space. SUMMARY OF THE INVENTION [0003] This document describes an aspirator for inflating an inflatable flotation device. The aspirator includes an aspirator body having at least one flapp...
