摘要： The present invention relates summarily to a multi-ejector device with at least one ejector part (2) including at least one array of ejector jets (18, 19, 20) placed one after the other in the ejector part (2). Under the action of compressed air flowing through them, the jets (18, 19, 20) generate a subpressure in chambers (11, 12) connected to the jets. The chambers (11, 12) are in communication via openings (13, 15, 17) provided with non-return valves (14, 16) with a vacuum collection chamber (9), to which the tool or the like driven by the ejector device is connected. The ejector part (2) is an element in the shape of a plate formed by moulding or in some other way, where the ejector jets (18, 19, 20) and the valve chambers (11, 12) are formed integrally in the plate-like piece. The ejector part (2) is suitably parallel epipedic in shape, with pairs of arrays of jets (18, 19, 20) extending lengthwise through it, with each array ajacent the long side of said part and the vacuum collection chamber (9) placed between two jets (19).
