Abstract

A device for supplying combusted gases at a controlled rate to the combustion chamber of an internal combustion engine having an intake pipe that accommodates a throttle (3) and an exhaust pipe. The intake pipe and exhaust pipe communicate through an exhaust gas recycling pipe with a shut-off valve (1) accommodated therein. Means (4) that operate the shut-off valve (1) and the throttle (3) can be activated only in common and by a common activating mechanism.
