Abstract

An apparatus for feeding fuel from a supply container to an internal combustion engine of a motor vehicle is described. The apparatus has a fuel feed unit which on the intake side communicates with a suction container, communicating with the supply container, and on the pressure side communicates with the engine, and having a return line for feeding excess fuel into the suction container. In its bottom region the suction container has a closing element, which is movable between a first position, in which the suction container is opened relative to the supply container, and a second position, in which the suction container is closed relative to the supply container. According to the invention, the closing element has an actuating device, preferably a float body, which in particular at a low or zero fuel level in the supply container keeps the closing element in the first, open position, and which, when at least enough fuel is located in the suction container that the fuel feed unit can still furnish enough fuel to the engine, keeps the closing element in the second, closed position.
