Abstract

A fuel supply device for internal combustion engines comprises a constant level chamber, an engine-driven fuel pump having an outlet connected to the constant level chamber and an inlet connected to a fuel reservoir through a pipe provided with a non-return valve. A capacity located on the pipe is defined by a wall movable between a first position where the capacity has a maximum volume and a second position where the capacity has a minimum volume. A spring continuously biases the movable wall towards the first position. The movable wall is drawn to the second position responsive to start up of the engine.
