Abstract
A l'aide d'une série de spires (8) enroulées autour du câble à haute tension (9) qui alimente le distributeur, on obtient un signal dont la valeur est proportionnelle an nombre de tours/minute. Ce signal est confronté avec un signal de référence dans un comparateur (16) qui commande un circuit logique (3), lequel intervient à son tour pour provoquer la désexcitation d'une électrovanne (6) insérée sur la canalisation de ralenti, et ce dans le cas où le nombre de tours du moteur dépasse une certaine valeur et dans le cas où simultanément le conducteur a relâché la pédale d'accélérateur (4). Dans tous les autres cas le circuit logique (3) permet l'excitation de l'électrovanne (6) et le fonctionne ment normal du moteur. Using a series of turns (8) wound around the high voltage cable (9) which supplies the distributor, obtains a signal whose value is proportional to an number of revolutions / minute. This signal is confronted with a reference signal in a comparator (16) which controls a logic circuit (3), which in turn intervenes to cause an inserted solenoid valve (6) to de-energize on the idling line, and this if the number of engine revolutions exceeds a certain value and in the if the driver has simultaneously released the pedal accelerator (4). In all other cases the logic circuit (3) allows the excitation of the solenoid valve (6) and operates it normal engine.
