Abstract
An electric control device for regulating the r.p.m. of a piston internal combustion engine is disclosed. The device has an integral r.p.m. regulator with an output connected to a final control element regulator electrically connected to an electromagnet that actuates an adjusting element of the engine. A nominal value signal and a signal from a tachometer are fed to the r.p.m. regulator. A current regulator is electrically connected between the r.p.m. regulator and the final control element regulator. The current regulator is acted upon by both a signal from the electromagnet and the r.p.m. regulating means by a summing element to control the final control regulator which acts on the electromagnet.
