FUELLING SYSTEM FOR LIQUEFIED NATURAL GAS VEHICLES

摘要

The fuelling system (1) for liquefied natural gas vehicles comprises: one tank (2) adapted to contain liquefied natural gas (L) intended to fuel one engine (3) of a vehicle (4); one safety valve (5) associated with the tank (2) and adapted to allow the escape of gaseous natural gas (G), generated by the evaporation of part of the liquefied natural gas (L), after reaching a predefined pressure value inside the tank (2); one main fuelling line (6) configured to take the liquefied natural gas (L) from the tank (2) and convey it to the engine (3); one secondary fuelling line (10) configured to take the gaseous natural gas (G) from the tank (2) and to convey it to the engine (3) and comprising: one storage vessel (11) adapted to store the gaseous natural gas (G); and one compressor assembly (12) positioned upstream of the storage vessel (11) and adapted to compress the gaseous natural gas (G).
