Abstract

a. L'invention concerne un dispositif limiteur de vitesse de rotation pour moteurs à combustion interne, comportant un étage détecteur de vitesse de rotation produisant des signaux utilisés pour supprimer des signaux de commande de l'installation d'allumage. b. Ce dispositif est caractérisé en ce qu'un étage réducteur de fréquence est associé à l'étage détecteur de vitesse de rotation pour supprimer des impulsions d'allumage à intervalles réguliers au-delà d'une vitesse limite. c. L'invention est applicable aux moteurs à combustion interne.at. The invention relates to a device for limiting the speed of rotation for internal combustion engines, comprising a stage for detecting the speed of rotation producing signals used to suppress control signals from the ignition system. b. This device is characterized in that a frequency reduction stage is associated with the rotation speed detector stage to suppress ignition pulses at regular intervals beyond a limit speed. vs. The invention is applicable to internal combustion engines.
