Abstract
Abstract Improvement in internal combustion engine carburetion devices of the type comprising an internal circuit for cooling the fuel, this circuit forming a circulation loop with the fuel tank, characterized in that the cooling circuit comprises a coil tubing mounted within the float chamber and connected in parallel to a fuel-circulation cooling jacket adapted to cool the passages through which fuel is fed to the main jet and idling jet.

Improvement in internal combustion engine carburation devices of the type comprising an internal circuit for cooling the fuel, this circuit forming a circulation loop with the fuel tank, characterized in that the cooling circuit comprises a coil tubing mounted within the float chamber and connected in parallel to a fuel-circulation cooling jacket adapted to cool the passages through which fuel is fed to the main jet and idling jet.
Claim 3
Dependent Claim
83 words
Device according to claim 1, of which the circuits for cooling the fuel feed circuit receive in common the fuel pump output, the output fraction fed to the main jet and/or idling jet passages being absorbed by the engine induction pipe and the output fraction fed to the cooling circuits is returned to the fuel tank, the fuel output delivered to the cooling and feed circuits being adjusted by means of an auxiliary circuit constituting a direct return line to the fuel tank.
Claim 4
Dependent Claim
27 words
Device according to claim 2, wherein the output adjustment means are responsive to thermostatic regulation means as a function of the desired fuel temperature in the carburetor.
