Ejector Theory - Croll Reynolds

The relation of a change between the motivating pressure and discharge pressure depends on the characteristics of the ejector design. Since an ejector is a "one point design", once a unit is designed and built to definite specifications of motivating pressure, discharge pressure and suction pressure, its suction capacity cannot be increased .

Injector - Wikipedia

An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts, excepting a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water .
