Abstract
An aspirator for inflating inflatable devices such as aircraft emergency evacuation slides and life rafts using a quantity of primary gas that is stored in a tank that within the aspirator entrains a secondary gas, typically outside air, as the primary gas flows through the aspirator thereby producing sufficient gas to inflate a large inflatable structure or device as described above. The aspirator typically has injectors therein which act to promote the entrainment of large quantities of the secondary fluid using small quantities of the primary fluid thereby resulting in a large combined flow of gas forcibly flowing into the inflatable structure.
