Fuel supply system for vessels fueled by alternative fuels and related vessels

摘要

Fuel supply system (4) for engines (8) of motor boats (12) of types outside on board and on board, said engines (8) being supplied with alternative fuels, the system (4) comprising: - at least one pressure regulator (24), wherein said pressure regulator (24) receives the fuel from a supply line (28) at a supply pressure and delivers it at an outlet, through a delivery line (32) at a delivery pressure, different from the supply pressure, to injection devices and / or solenoid valves that supply fuel to the engine (8), - said supply and delivery pressures are greater than the ambient pressure, characterized by fact that: - the system (4) comprises at least one closed container (40) that identifies an interior volume (44) containing said pressure regulator (24) and, at least partially, said supply ducts (28 ) and delivery (32), - the recipient closed (40) sealed in a completely hermetic way to the gaseous fuel, in relation to the fuel that passes through the devices contained therein, where said fuel is supplied at a pressure higher than the ambient pressure in which the system is located (4), - said closed container (40) comprises at least one vent (48) in fluid communication with the inner volume (44) of the container (40), the vent (48) connects said inner volume for fluid transmission (44) with the environment outside the system (4) and with the relative vessel (12) in which the system (4) is installed, to channel the fuel leaks, at a pressure higher than the ambient pressure, towards the outside of the boat (12).
