ABSTRACT:
An ejector device which has at least two ejectors formed by a corresponding number of axially aligned nozzles of increasing cross section in the direction of flow. The device is formed as a series of modules, each module having a transverse wall and a section of housing. These housing sections abut each other to form chambers between these transverse walls. The transverse walls contain the aligned nozzles and also openings between the chambers with one way valves permitting fluid flow only in the direction of flow through the nozzles. Various arrangements are provided for connecting the housing sections together. A valve arrangement permits selectively eliminating the vacuum in the first chamber.
