<p>The invention relates to an ejector for a pneumatic transport system with nozzles for the propellent gas which open out peripherally. It comprises a housing (4) with a conical insert (6). Recesses in the insert and the surrounding surface in the ejector housing from a channel (10) with a cross section (diffusor) which continuously increases from an inlet (10a) for the propellent gas, where the propellent gas expands and attains a high velocity. These channels (10) open out at the periphery in the flow channel of the ejector and constitute the nozzles of the ejector.</p> |
