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.

Fuel supply device for an internal combustion engine

A fuel supply device for an internal combustion engine comprises a constant level chamber (typically a float chamber) formed in a casing which may be the body of the carburetor of the device. A heat exchanger is formed in the casing or in contact with the casing. A cooling liquid is circulated in a closed-loop circuit including the heat exchanger and a liquid reservoir having a large volume as compared with that of the balance of the circuit.

Fuel supply device with cooled flow chamber

A carburettor has an acceleration pump whose movable wall is mechanically actuated by the throttle valve. The acceleration pump is disabled as long as the engine is at rest. For instance, the movable wall may be separated from the throttle valve or locked in a rest position.
