description -13 Abstract FUEL SYSTEM AND ENGINE HEAD ASSEMBLY HAVING DOUBLE-WALLED FUEL CONNECTOR FOR COOLING FUEL RETURN An engine head assembly (20) includes a double-walled fuel connector assembly (52) in an engine head (18) and forming a high-pressure fuel supply passage (54) and a low pressure fuel return passage (56). The engine head assembly also includes a fuel injector (24). A high-pressure fuel inlet path (87) extends between a fuel inlet (68) and spray orifices (76) through an injector body (66) in the fuel injector. A low-pressure cooling fuel outlet path (89) extends between an injection control valve seat (80) in the fuel injector and a cooling fuel outlet (64) in a nozzle case (62) of the fuel injector. Expelled cooling fuel is passed through the low pressure fuel return passage in the double-walled fuel connector. NI, Nt %0 lin :C,4 C'4 %D %0 lLrI N CZ4 :q !C,4 ,Ln Ln fn rN cq rn
