ABSTRACT:
Noise from fuel returning to a cylinder and from bubbles contained in the returning fuel is reduced by positioning a nozzle with a plurality of penetration holes, each with much less sectional area than a flow sectional area for returning fuel. The nozzle is also equipped with a guide section installed to change the proceeding direction of the fuel passing through the penetration holes and the fuel return valve.
