Pressure regulator (4) for fuel systems (8) for motors (12) of alternatively fuelled motor boats, comprising a regulator body (20) which encloses an expansion chamber (24) which receives the fuel through a fuel inlet (28) at the supply pressure and allows its expansion and exit through a fuel outlet (32), at the delivery pressure. Around the expansion chamber (24) there being provided a heat exchange duct (36) having a coolant fluid inlet (40) and a coolant fluid outlet (44) so as to create a circulation of the motor coolant fluid (12) inside the pressure regulator (4). Advantageously, at least the heat exchange duct (36) of the regulator body (20) is made from at least two separate materials comprising a first base material and at least one layer of coating in corrosion-resistant material. |
