The solution according to the invention has several significant advantages. The use of liquid mist as a driving medium provides a very effective suction effect. In addition, a significant energy saving effect of up to 50% is achieved compared to compressed air ejector equipment. In addition, liquid mist is a very effective medium for removing particles and reducing odor nuisance with an ejector device. By arranging the circulation of the sprayable medium, a highly effective and water-consuming effect is achieved. Also for recyclable drive media. . chemicals can be added if desired. By arranging the ejection • · · * · ”jacketed portion of the jacketed portion, preferably * ·: ·; a vented opening for the removal of transport air. By arranging the aperture closure member to close, for example, in a congestion of the transfer tube - "" · * 25, the suction effect of the ejector can be enhanced. At the same time, it helps to clear the blockage. By coaxially arranging the nozzle in the suction tube, the ejector power can be further increased. By providing a rotating motion for the liquid separated in the separating member, it is possible to enhance the separation and possible contact of possible impurities from the liquid.

By adding to the apparatus a further possibility of feeding a second medium to the ejector device, it is advantageous, on the other hand, to further reduce any odor nuisance in the ejector device and, at the same time, * * * enhance suction. By bringing the second medium together with the working medium. ! ·. with and, if necessary, using the pressure of the operating medium to introduce and / or feed 35 materials into the ejector space, a very inexpensive and effective solution is achieved.

At the same time, a good solution for enhancing the suction of the ejector device is achieved. When using a higher density agent such as a liquid, preferably water can enhance the suction effect. On the other hand, the introduction of a second medium can further improve the suction effect, even if the driving medium is a liquid or a mixture of liquid and gas. When used as a working medium and / or at least another medium, it can be spray-sprayed to "wash" the gas stream and thereby eliminate any particulate and odor nuisance. By using a separate pump to deliver the second medium, one can easily adjust its import. In addition, the ratio of the operating medium to the second medium can be adjusted at the same time. By adjusting the pressure of the propellant to the ejector as needed, significant energy savings are achieved. In addition, the pressure is controlled by the suction provided by the ejector, whereby the vacuum and / or pressure difference of the material transfer tube can also be conveniently adjusted. By using parallel flow paths for pressure control with a throttle member and a valve that is opened and closed on the basis of the pulses of the control system, a very useful control system is obtained which is easily modified. Transport of the material may, if desired, be initiated at a higher pressure exerted on the ejector 20 and, as the transfer process progresses, reduced pressure.
