DEVICE TO MEASURE THE MOVEMENT OF A SHUTTER OF AN INJECTOR

A device to measure the movement of a shutter (2) of an injector (3) has a laser emitter (20) to generate light radiation, a receiver (23) associated with the laser emitter (20), a housing seat for the injector (3), which is arranged so as to allow the shutter (2) to move through the light radiation generated by the laser emitter (20), and a control unit (25), which is configured to generate a signal indicating the movement of the shutter (2) based on the quantity of light radiation generated by the laser emitter (20) and gathered by the receiver (23) itself.
