Abstract
The invention provides a jet pump comprising a housing containing a nozzle into which an injected fluid is introduced, the housing also possessing a suction orifice, the pump comprising, upstream from the outlet of the nozzle, an auxiliary chamber associated with two sealing elements, each sealing element being adapted to open when the pressure of the injected fluid exceeds a predetermined level, the first sealing element opening at a first pressure level, the second sealing element opening at a second pressure level greater than or equal to the first.
