Fuel injector with an antirebound device

摘要

A fuel injector ( 1 ) having an injection valve ( 7 ) with a movable pin ( 15 ); and an actuator ( 5 ) for moving the pin ( 15 ) between a closed position and an open position; the actuator ( 5 ) has a movable armature ( 10 ), and an antirebound device ( 20 ) interposed between the movable armature ( 10 ) and the pin ( 15 ) to connect the movable armature ( 10 ) and the pin ( 15 ) mechanically; the antirebound device ( 20 ) has a deformable elastic plate ( 32; 45; 48 ) which is annular in shape, is connected centrally to the pin ( 15 ), and is connected laterally to the armature ( 10 ) to transmit at least the closing movement of the injection valve ( 7 ) from the armature 15 ( 10 ) to the pin ( 15 ).
