Abstract

The present invention relates to a device for recirculation of exhaust gases of a combustion engine (1). The recirculating exhaust gases are intended to be led from an exhaust line (3) of the combustion engine (1) via a return line (9) to an inlet line (7) which is intended to lead air to the combustion engine (1). The device (11) can be fitted close to a connection between the return line (9) and the inlet line (7). The device (11) comprises means (13, 15, 19) for controlling the flow of exhaust gases from the return line (9) to the inlet line (7) and for mixing the exhaust gases with the air in the return line (7).
