摘要： Ejector (1) comprising two or more nozzles (2, 3, 4, 5) arranged in series, wherein a stream of air fed at high velocity through the nozzles is used to create a negative pressure in an outer, surounding space (V, V'), the surrounding space being in flow communication (10) with at least one slot (7, 8, 9) located between the nozzles, wherein the nozzles are coupled together and assembled into an integrated nozzle body (1) having at least one flexible valve member (11) integrally arranged within the nozzle body to cover the flow communication (10) with the surrounding space upon reaching a certain, desired pressure difference between the surrounding space and the atmosphere.
