A gasifier/pressure reducer device in self-propulsion systems with gas-fuelled motor, particularly LPG, comprises a main body, in which an entrance passage of a fluid communicating with a tank of fluid under pressure and an exit passage of gas at the required pressure, connected to a utility, shut-off devices of the fluid associated with the entrance passage, a gasifier circuit made in a first portion of said body and comprising a heat exchanger able to transform, in a gasification duct, the fluid entering into a gaseous state suitable to fuel the engine, and a regulator stage of the pressure of the gas supplied housed in a second portion of the main body, downstream of the gasification circuit, are made. The regulator stage comprises a piston pressure regulator. An obturator body of a valve seat placed between the gasification duct and the exit passage of the gas is operatively connected to the piston in such a way that said obturator body opens or closes said valve seat depending on the pressure value of the gas present in the exit duct and acting on the piston. |
