    摘要： 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.

    摘要： The present invention relates shortly to an ejector device having an adjustment characteristic which is stepless variable in dependence of the negative pressure generated by the ejector device. Said ejector device comprises a portion (16) for connection with a source of positive pressure delivering the work pressure to the ejector device (1) giving rise to the ejector action and a portion (2) having connection (18) for the member which is intended to use the negative pressure created by ejector device (1). Said two portions (16, 2) of the ejector device (1) are stepless movable in relation to each other and in the space therebetween there is an adjustment plate (13) for controlling the suction action obtained by the ejector device (1). The outlet slit (17) of the ejector device (1) is located between the plate (13) and the portion intended for connection with the positive pressure source. The adjustment plate (13) is connected to a stem (10) which is movable in relation to the portion (2) for connection with the negative pressure member but which is fixed in relation to the portion (16) to which the positive pressure source is connected.
