Abstract: An injector of gaseous fuels for internal combustion engines comprises a valve body (2) into which the fuel is admitted by means of an inlet aperture (4) and from which it is discharged by means of an outlet aperture (5), a seating (6) associated with a respective shutter (7), the shutter comprising a diaphragm (9) and a moving armature (10) of an electromagnet (8) held in a centred position by the diaphragm, the electromagnet being capable of causing, in a controlled manner, movement of the shutter (7) relative to the seating (6) from and to a position of shutting off the seating to allow or shut off the flow of fuel through the seating (6). The seating (6) has a cross-section for passage of the fuel having the form of at least one slot (6a, 6d) extending along a first direction of development predominant with respect to a second direction of transverse development of the cross-section and the cross-section has a perimeter sealing edge (6b) with a cross-section of substantially rounded shape capable of providing sealing contact against a surface (7a) of the shutter (7) facing it.
