An ejector device consists of a number of ejector units each of which includes a suction chamber. The individual units are positioned in a common housing. For making the ejector the housing is produced and the suction chambers are produced therein. These latter are four sided recesses. The holes are made in the partitions between the chambers and in the walls of the housing and nozzles are fixed in these holes. In a further step a flexible cover is placed on the open sides of the chambers. There are openings in that cover. It is covered by a rigid plate with an opening and a second flexible cover is placed on the plate. Finally a second housing is secured to the assembly. Inlet and outlet ports are provided in the second housing. |
