Abstract
The system (10) for supplying petrol vehicles with liquefied petrol gas (LPG) comprises: an LPG recipient (G); an LPG supply pump (PG), external of the LPG recipient; a first fluid passage circuit (1) comprising a first solenoid valve (V1) and a sealed containing portion (11) for containing LPG at a constant pressure, connectable between the LPG recipient (G) and the LPG supply pump (PG); a first pressure detecting sensor (P1), for detecting the LPG pressure value present internal of the portion (11) in such a way that the first solenoid valve (V1) can be commandable to regulate the injection of LPG internally of the portion (11) such as to guarantee a continuous presence of LPG at constant pressure in the portion (11); a second fluid passage circuit (2) connectable between the pump (PG) and the petrol supply channel (CB) to the injection device-motor group (M) of the vehicle and comprising a second solenoid valve (V2); a third fluid passage circuit (3) communicating with the sealed containing portion (11) and connectable with the petrol supply pump (PB), in a position at the outlet of the petrol supply pump (PB) of the vehicle and comprising a third solenoid valve (V3), which is commandable such as to enable, during the passage step from LPG to petrol supply, placing the pump (PB) in series with the pump (PG) in such a way that the petrol can be supplied to the group (M) via the second circuit (2), with a pressure such as to push any LPG in the gaseous state, present internally of the group (M), to exit from the group (M); and a fourth fluid passage circuit (4) to enable return of the LPG to the gaseous state, pushed out of the group (M), to the LPG recipient (G).
