Claim 0:
1. A jet pump comprising a jet nozzle for accelerating a propellant, wherein the jet nozzle has a convergent inlet portion and an outlet portion which is connected to the convergent inlet portion, wherein the outlet portion comprises an inner space which is surrounded by an inner wall and which diverges at an opening angle, wherein the inner wall defines the opening angle relative to the narrowest cross section at an inlet opening of the inner space, wherein the opening angle is constructed in such a manner that a propellant which flows through the outlet portion at subsonic speed is released from the inner wall, wherein the outlet portion does not operate as a diffuser for the propellant which is flowing at subsonic speed therethrough and a propellant which flows through the outlet portion at supersonic speed is guided by the inner wall, wherein the opening angle is greater than 7°.
