An injection duct (14), which is created when the injection valve (7) is in the open position, has a converging initial segment, in which an area of the injection duct (14) progressively decreases from a first maximum value at the beginning of the injection duct (14) to a minimum value, and a diverging final segment, in which the area of the injection duct (14) increases from the minimum value until reaching a second maximum value.",
