Abstract: Fuel pump for an internal combustion engine, wherein the fuel pump has: an auxiliary tank designed to receive a fuel flow from a low-pressure fuel pump; a pumping device drawing the fuel from the auxiliary tank through a suction duct; a Venturi choke arranged along the suction duct; and a degasification duct, which originates in a ceiling of the auxiliary tank and leads to the middle of the Venturi choke.

Abstract: A canister purge valve for an internal-combustion engine is provided with a housing including a supply channel that connects a fuel-vapor inlet port to a fuel-vapor outlet port. A valve scat is disposed across the supply channel. A valve shutter has a pressure-compensating channel and is movably mounted within the supply channel to move from an “open” position, in which the valve shutter is distant from the valve seat, to a “closed” position, in which the valve shutter is pressed against the valve seat. A rigid stem is mechanically coupled to the valve shutter to move the valve shutter from the “open” position to the “closed” position and seals the; pressure-compensating channel in the “closed” position.
