Abstract

A device for injecting a liquid fuel in an internal combustion engine, comprising a piston pump that is driven by said engine and whose suction orifice is connected by means of a conduit to a fuel container, while its valve drive is connected to the injector of a cylinder of said motor; said device being characterized by the fact that the displacement of said pump is much higher than the volume of fuel that must be carried to the cylinder of the engine in each injection, that the suction pipe is provided with a passage of calibrated section that limits the flow of suction and that said pump comprises means for bringing the cylinder of the pump into communication with a low pressure zone during most of the pump drive cycle and, at least in the part near the end of said cycle, said communication means being interrupted, to allow the fuel to be driven towards the injector, at least during a reduced intermediate part of this pump cycle.
