Abstract

A compressible gas ejector is configured to present unexpanded motive gas to a load gas, wherein the interface of the unexpanded motive gas and the load gas can be located in a suction chamber or within a downstream diffuser. The ejector includes a motive funnel for increasing the velocity of a relatively high pressure motive gas, the motive funnel substantially precluding adiabatic expansion of the motive gas.
