Abstract

Fuel injection device for an internal combustion engine, and engine equipped with such a device. The device includes a first cavity (3) forming part of a fuel pressurizing member (3, 4, 5), and a second cavity (12) made in an injector (9), in which cavity the pressure tends to lift a movable needle (11), against the action of the pressure in an accumulator (20), transmitted by a pipe (35). The first cavity (3) is separated from the second cavity (22) by a one-way valve (30).
