An injector for a system for feeding gas fuel to an internal combustion engine has an inlet mouth for the fuel into the injector, houses therein a shutter which is moveable between a closed position and an open position of an outlet mouth of the fuel from the injector, and is defined by an inlet body provided with the inlet mouth and a first actuating device to displace the shutter in an open position thereof and at least two interchangeable outlet modules, each of which is adapted to be releasably fixed to the inlet module, and is provided with a relative outlet mouth, a relative shutter, and a relative second actuating device to displace the shutter in a closed position thereof. |

1. An injector for a system (2) for feeding gas fuel to an internal combustion engine (3), the injector comprising an inlet mouth (8) for the fuel into the injector; an outlet mouth (26; 51) of the fuel from the injector; and a valve device, which is arranged between the inlet mouth (8) and the outlet mouth (26; 51), and comprises, in turn, a shutter (29), a first actuating device (16) to displace the shutter (29) in an open position, in which the inlet mouth (8) and the outlet mouth (26; 51) are connected to one another to allow the feeding of fuel to the outlet mouth (26; 51), and a second actuating device (33) to displace the shutter (29) in a closed position, in which the inlet mouth (8) and the outlet mouth (26; 51) are separate from one another to prevent the feeding of the fuel to the outlet mouth (26; 51); the injector also comprising an inlet module (6) provided with the inlet mouth (8) and with the first actuating device (16); at least two interchangeable outlet modules (21; 49), each of which is provided with said relative outlet mouth (26; 51), with said relative shutter (29), and with said relative second actuating device (33); and locking means (24) to releasably lock the outlet modules (21; 49) on the inlet module (6);
characterized in that the inlet mouth (8) has a first longitudinal axis (9); in that the outlet mouth (51) of a second said outlet module (49) having, at least at an outlet segment (52) thereof, a second longitudinal axis (53) transversal to the first axis (9); and in that the outlet mouth (26) of a second said outlet module (21) has a third longitudinal axis (27) parallel to the first axis (9). |
