An arrangement for mixing a first and a second gas flow, for example, an inlet flow with a exhaust gas return flow in a diesel engine, comprising a line ( 16 ) for the first flow, an inlet ( 7 ) for the second flow in the line ( 16 ), in order to achieve the mixing; a streamlined body ( 8 ) arranged to be displaced in the longitudinal direction of the line ( 16 ) at the inlet ( 7 ) in order to achieve a variable venturi effect and in this way a variable suction effect and mixture of the mixed flow; and actuating means for displacing the body forwards and backwards in the line. In order to minimise the need for throttling and the accompanying pressure losses, the streamlined body ( 8 ) and the supply part ( 2 ) are designed to achieve maximal throttling in the line ( 16 ) close to the inlet ( 7 ), independently of the position of the body.
