Abstract
An arrangement for supplying fuel from a supply tank to an internal combustion engine of a power vehicle comprises a supply aggregate arranged to be located in a supply tank and a supply pump provided with a suction opening, a suction chamber having a first opening communicating with an interior of the tank and a second opening, a storage chamber supplied from fuel return conduit extending from the internal combustion engine and communicating with the suction chamber through the second opening, a blocking member arranged in the suction chamber and forming a valve with a limiting structure of the second opening, the valve closing the second opening until the suction opening formed in the suction chamber is immersed in fuel which flows from the tank into the suction chamber, the blocking member being arranged in a fuel suction stream and held from the latter on an abutment facing toward the suction chamber, whereby it releases the first opening, the blocking member in the event of an interruption in the fuel suction stream releases the second opening and blocks the first opening.
