Abstract

ABSTRACT ‘ELECTROMAGNETIC FUEL INJECTOR WITH BRAKING DEVICE’ A fuel injector (1) provided with an injection nozzle (3); an injection valve (7), which has a movable needle (17) to adjust the flow of fuel through the injection nozzle (3); and an electromagnetic actuator (6), which is adapted to move the needle (17) between a closing position and an opening position of the injection valve (7) and is provided with a movable plunger (9) which is mechanically connected to the needle (17) and has at least one feeding through hole (30) for the passage of fuel towards the injection nozzle (3); the plunger (9) is provided with a braking device (36) of the hydraulic type, which is coupled to the feeding hole (30) and has the function of hydraulically dissipating kinetic energy to slow down the opening stroke of the needle (17) when the needle (17) moves towards the opening position of the injection valve (7).
