An electronic rotational speed control device for internal combustion engines of large power output with a desired-value adjustment for the rotational speed and filling of the internal combustion engine, a desired-actual-value comparison of the rotational speed, a control stage, an amplifier, and adjusting member with a servo-valve for the filling control which is provided with a motion pickup and a feedback; a pure rotational speed control stage with P-I-D behavior or a filling-rotational speed control stage can be selectively engaged while between the control stage and amplifier a filling-limit signal intended to limit the engine filling is compared with the filling-signal produced by the control stage whereby the respective smaller signal is transmitted to the amplifier; two measuring systems are provided for the rotational speed measurements which are utilized selectively for the supply of the rotational-speed existing-value and which can be connected by way of an OR-circuit so as to act, in case of excess rotational speed, on a stoppage mechanism of the internal combustion engine.
