Abstract

The fuel feed device includes an injection valve actuated by an electromagnet which is energized over a variable fraction of each revolution of a rotating member driven by the engine. On acceleration with the opening of the main throttle member of two throttle members it is advantageous to increase the richness of the air/fuel mixture admitted to the engine to obtain freer and more regular acceleration. The source of fuel under pressure is constituted by a fuel pump on the delivery pipe of which acts a pressure regulator which comprises a relief valve tending to open under the effect of the delivery pressure of the pump and to close under the effect of the suction existing in the section of the intake pipe comprised between its two throttle members. The suction is transmitted by a linking channel to a diaphragm to which the relief valve is coupled. The variable volume chamber is connected to the linking channel between a calibrated orifice and the diaphragm of the pressure regulator and is controlled by means adapted to increase its volume on opening of the main throttle member.
