The flow rate adjustment device (10) has a containing element (19), which houses the electromagnetic actuator (12), has an open end (21) facing the intake valve (8), and ends with a \"U\"-shaped rim (27) which has an outer ring which is arranged around the containing element (19) at a given distance from a cylindrical wall (24) of the containing element (19). An annular weld (22) is obtained between the main body (2) and the outer ring of the \"U\"-shaped rim (24).",
