The liquefied petroleum gas feeding installation for motor vehicles is applicable to the liquefied petroleum gas stations for feeding said stations and also for feeding the motor vehicles from a supply panel. The feeding is performed mainly from a stationary tank (1) provided with a valve (8) for the liquid phase and a valve (10) for the excess gas in the liquid phase, each of said valves branching out in two ducts used both for feeding from a movable tank (11) and for feeding a panel (A) for the liquid-phase liquefied petroleum gas supply. The fuel meter in panel (A) is degassed through a duct provided with a valve (32) connected to a nipple (4) on the stationary tank (1). In order to feed the stationary tank (1) with liquefied petroleum gas, the liquid-phase duct comprises a valve (8), a valve (16) with a resilient connection, which is continued with a valve (14) communicating with the movable tank (11), while the gas phase duct comprises a valve (10), a valve (17) having a resilient connection, continued with a valve (15) communicating with the movable tank (11). In order to supply the liquid-phase liquefied petroleum gas to said panel (A), the duct is provided with a valve (8), a valve (12), a pressure gauge (18), a safety valve (19), a filter (20), a pressure gauge (21), an electric pump (22) and a non-return valve (23), then the duct branches out in two parts. One duct branch for excess gas further comprises a by-pass valve (30), a valve (31) and a valve (13) communicating with a valve (10). The other duct branch further comprises a direction valve (24), a pressure gauge (25), a safety valve (28), an electrovalve (29) to the panel (A), wherefrom the liquid-phase liqufied petroleum gas is supplied to motor vehicles, on demand.
