Abstract: Method of achieving with at least two compressed air operated ejectors a desired subpressure in the shortest possible time and with the least use of energy, this method including connection of the ejectors such that they work one at a time in response to which of them is supplied with compressed air. In turn, compressed air supply is controlled in respons to the subpressure in a subpressure collection chamber common for all ejectors. An ejector array (1) for the method includes at least two compressed air operated ejectors (2, 3) each having its own optimum efficiency at the same values of the supplied compressed air. A sensor is disposed for sensing the subpressure in the chamber (23), compressed air being supplied to one ejector (2, 3) at a time, in response to the sensed pressure in the chamber (23). Compressed air is first supplied to the ejector (2) evacuating the greatest amount of air per time unit, and last to the ejector (3) generating the lowest subpressure.

Abstract: The present invention relates summarily to a mult-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 parallelepipedic 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).
