FUEL SUPPLY APPARATUS FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To clear up such a problem that when a pressure regulator is inter nally mounted in a casing 1 of a fuel pump, a seal cylinder body of which the pressure regulator consists is arranged on the extension line of a rotor core axis. SOLUTION: A rotor core shaft 7 is rotatably situated on the outer periphery of a hollow shaft 5 fixed at a casing 1 and forming a seal cylinder body and forms a No. 10 structure where a hollow shaft 54 and a rotor core shaft 7 are overlapped with each other to prevent too lengthening of a fuel pump.
