Abstract

Dispositif de carburation qui comporte un papillon actionné par le conducteur et un organe d'étranglement auxiliaire dont la position est représentative du débit d'air et qui commande un organe doseur réglant le débit de combustible aspiré vers une arrivée de déchargé dans le conduit d'admission. L'organe doseur comporte une soupape électromagnétique 29 commandé par des impulsions électriques fournies par un circuit 33 comportant un potentiomètre 30 couplé à l'organe d'étranglement auxiliaire 16. L'orifice de décharge 26 est placé au col d'un venturi formé par un étranglement du conduit d'admission et l'organe d'étranglement auxiliaire. Application aux moteurs à combustion interne.Carburetion device which comprises a butterfly actuated by the driver and an auxiliary throttle member whose position is representative of the air flow and which controls a metering member regulating the flow of fuel sucked towards an inlet of discharged in the duct of admission. The metering member comprises an electromagnetic valve 29 controlled by electrical pulses supplied by a circuit 33 comprising a potentiometer 30 coupled to the auxiliary throttling member 16. The discharge orifice 26 is placed at the neck of a venturi formed by a throttle of the intake duct and the auxiliary throttle member. Application to internal combustion engines.
