摘要： The high-pressure pump (7) comprises a number of pumping elements (18) actuated in reciprocating motion through corresponding suction and delivery strokes. Each pumping element (18) is provided with a corresponding intake valve (25) in communication with an intake pipe (10) supplied by a low-pressure pump (9). Set on the intake pipe (10) is an on-off solenoid valve (27) having a reduced flow rate substantially of the same order of magnitude as the maximum amount of fuel that can be injected by an injector (5). The solenoid valve (27) is controlled in a chopped way in synchronism with an intermediate part (32) of the suction stroke of each pumping element (18).

摘要： A fuel tank for motor vehicles, for example an LPG fuel tank, contains inside it at least one electrical component and has a wall or a plate bearing at least one connector for connection of the electrical component with an electrical line external to the tank. The electrical connector has a body made of synthetic material or of elastomer material directly moulded on one or more conductor pins so as to guarantee hermetic sealing of the tank even in the presence of a pressure jump between the internal cavity of the tank and the external environment. In the case where the body of the connector is made of synthetic material, it bears seats for seal rings made of elastomer material. In the case where it is made of elastomer material, it guarantees directly the function of tightness. In either case, there are provided means for exerting an axial compressive force on the part that performs the tightness function.

摘要： In a system for feeding LPG by injection for an internal combustion engine, sensor means are provided for measuring the electrical current absorbed by the electric motor for driving the feed pump. The operation of said electric motor is interrupted when the measured electrical current absorbed drops below a predetermined threshold value. The system thereby prevents the operation of the motor-pump assembly, which is immersed in the LPG within the LPG tank, when the level of LPG in the tank drops below a minimum admissible value. Simultaneously to the interruption of the operation of the electric motor an auxiliary petrol feed system is activated.
