Abstract
A fuel injector has a fuel inlet, and a metering valve which is activated by an electromagnetic actuator to open and close an injection nozzle; the metering valve has a control chamber communicating with the inlet and defined by an end wall, in which is formed an outlet hole closed by a shutter moved along an axis by the actuator; the end wall and the shutter are defined by respective parallel, facing surfaces which rest against each other to compress the film of fuel issuing from the hole during closure by the shutter, and which have channeling formed about the hole to generate, in use, a counterpressure for the outflowing fuel.
