A device for protecting internal combustion fuel injection engines from overspeeding which comprises a closing member having the form of a revolving flap (2) installed in the supply conduit (1) of the engine, controlled by the air flowing through and adapted to close the supply conduit (1) at a predetermined air flow speed corresponding to the maximum permissible engine speed. Flap (2) is over shaft (3) coupled with lever (4) connected with tension spring (5). In the course of normal operation of an engine, flap (2) is maintained by spring (5) and stop (7) at angle alpha in relation to the axis of the supply conduit (1).
