The present invention relates to control devices and can most advantageously be used in load control devices for turbo-supercharged diesel engines operating over a wide range of operating conditions when frequent unsteady periods of operation caused by variations in the load take place. This control device comprises a crankshaft speed measuring mechanism, a pilot valve, a servomotor with a tailrod, a passage providing hydraulic connection of the pilot valve with the servomotor. A servomotor tailrod stroke limiter is mounted within said passage and comprises a stationary fixed casing, a sleeve and a plunger, both movable with respect to the stationary fixed casing and with respect to each other. The sleeve is connected to a pressure sensor, while the plunger, to the tail-rod of the servomotor. Such a constructional arrangement enables a separate control of the load as a function of air supply and fuel supply.
