<p>Improvement in diffuser/mixer devices for gas feeding systems, particularly lPG or methane gas systems, particularly for motor vehicles, comprising connection/intake means for the gaseous fuel, toward and within the engine feeding conduit. The connection and suction means for the gaseous fuel (4) toward and within the feeding conduit of the engine are made up of an annular chamber (6) having a radially inner diameter substantially corresponding to the diameter of the engine feeding conduit and in communication with said feeding conduit by a frusto-conical annular conduit (11) and with the radially outer side (3, 7) for the inlet of the gaseous fuel (4), as well as a further radial conduit (14) exiting into a coaxial biconical central bushing (13) supported by the arm (12). Advantageously, the frusto-conical annular conduit (11) has a port variable between a maximum and a minimum value.</p> |
