An ejector includes two or more nozzles arranged in series. A stream of air fed at high velocity through the nozzle is used to create a negative pressure in an outer, surrounding space. The surrounding space is in flow communication with at least one slot located between the nozzles. The nozzles are coupled together and assembled into an integrated nozzle body having at least one flexible valve member integrally arranged within the nozzle body to cover the flow communication with the surrounding space upon reaching a certain, desired pressure difference between the surrounding space and the atmosphere.
