The present invention relates to a governor device for an internal combustion engine where a portion of the engine output is taken off as driving force for vehicle mounted accessory equipment which requires constant speed rotation with changes in load. By controlling the intake air quantity passing through a bypass passage which bypasses a mixing device for mixing fuel and intake air at a predetermined ratio, controlling a sub-throttle valve provided in an intake passage in series with a main throttle valve, and controlling a supply quantity of auxiliary gas fuel so that a detected air-fuel ratio is constant, the engine output is increase/decrease controlled in spite of changes in load in accessory equipment, to give constant engine rotational speed and good operability of an auxiliary power take-off device.
Cette invention concerne un régulateur de régime pour moteur à combustion interne dont une partie de la puissance sert à entraîner des accessoires exigeant un régime de rotation constant en dépit des variations de charge. En régulant la quantité d'air admis passant par une dérivation contournant le dispositif de mélange de l'air et du carburant selon un rapport prédéterminé, en modulant un papillon secondaire monté en série avec le papillon principal dans le tube d'admission d'air et en régulant un appoint de carburant gazeux de manière à maintenir le rapport air-carburant constant, la puissance du moteur est modifiée à la hausse ou à la baisse sans égard aux variations de charge des accessoires pour maintenir un régime de rotation constant favorisant le bon fonctionnement d'une prise de force auxiliaire.
