Title (EN) CHOKE FOR ENGINES
(FR) STARTER POUR MOTEURS
Abstract:
(EN) This invention is characterized in that a starting fuel pump (49) for use in sucking a fuel from a fuel tank (25) and supplying the fuel to a starting nozzle port (41) of a carburetor (17) is driven by a fuel supplying electric motor (53). In order to start the engine, the motor (53) is rotated to suck the fuel from the fuel tank (25) by means of the pump (49) and supply the same to the starting nozzle (41), whereby the density of the gaseous mixture is increased to render the gaseous mixture easily ignitable. Thus, the engine can be started by either a starting electric motor or a recoil starter.
(FR) Cette invention est caractérisée en ce qu'une pompe (49) de carburant de démarrage, destinée à aspirer un carburant provenant d'un réservoir de carburant (25) et à alimenter en carburant l'orifice d'entrée (41) du gicleur de démarrage d'un carburateur (17), est mue par un moteur électrique (53) d'alimentation en carburant. Afin de démarrer le moteur, le moteur (53) est tourné pour aspirer le carburant provenant du réservoir de carburant (25) au moyen de la pompe (49) et pour l'amener au gicleur de démarrage (41), de sorte que la densité du mélange gazeux est augmentée afin de rendre le mélange gazeux facilement allumable. Ainsi, on peut démarrer le moteur soit au moyen d'un moteur électrique de démarrage soit au moyen d'un démarreur à détente.
