The present disclosure provides an ejector that comprises a housing portion and first and second fluid inlets. The ejector further comprises a fluid outlet and a fluid nozzle that is positioned in the housing and coupled to the first fluid inlet. The fluid nozzle is arranged such that a first fluid that is received by the first inlet at a first pressure PI has a second pressure P2 after passing through the fluid nozzle. The pressure P2 lower that the pressure PI. The ejector also comprises a mixing region that is arranged such that the first fluid when passing through the mixing region draws a second fluid from the second fluid inlet such that the first and second fluids mix. The ejector has an ejector diffuser region that has a cross sectional area that increases in diameter in a direction towards the fluid outlet and is arranged such that the mixture of the first and second fluid exits the ejector through the fluid outlet with a third pressure. The ejector is arranged such that a position of an outlet of the fluid nozzle relative to the mixing region is adjusted dependent on PI P2 and/or P3. |
