Abstract (en)
[origin: WO2020043499A1] The aim of the invention is to provide a device for conveying a suction medium by means of a motive medium, which device allows control of the flow of the motive medium and of the suction medium. In particular, the control should make it possible to completely stop either the flow of the motive medium and of the suction medium or only the flow of the suction medium. This aim is achieved based on the idea of closing a check valve in the suction line for the suction medium temporarily by means of the motive medium. The conveying of the motive medium and of the suction medium is stopped by closing a shut-off valve in the flow path between the motive medium inlet and the outlet of the device.
