Abstract

Disclosed is an aspirator system comprising a collapsible / expandable aspirator air passage wherein a burstable seal is provided for trapping air across the outlet passage, wherein the trapped air forms such that the aspirator Stretching to the pressure of its extended state, whereby the seal bursts and opens the air passage.

Description

Background technique [0001] Inflatable emergency evacuation devices, such as aircraft evacuation slides, emergency life rafts, and the like typically include an inflatable cylinder and an aspirator. Such devices are typically stored in limited packaging space and are therefore often densely packed. High packing densities can lead to various problems including cracked getters, which can be fragile. Accordingly, it is desirable to minimize the bulk of an inflatable emergency evacuation device in its packaged state. Contents of the invention [0002] According to various embodiments, a suction system is disclosed comprising an air passage movable between a contracted state and an extended state, the air passage comprising: a suction body having a longitudinal axis, a suction barrel , the suction barrel is in translational engagement with the suction body, and a nozzle assembly disposed within the suction body and configured to direct gas through the air passage, and a pressur...
