Inventor: UDA HITOSHI
IPC: F02M37/00
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device for an internal combustion engine for preventing vapor lock and fuel vanishment on the fuel injection valve side and preventing fuel leakage from a fuel injection valve by preventing an increase in fuel pressure caused by a backflow of fuel from a fuel tank. SOLUTION: A solenoid opening-closing valve 32 is closed at engine stopping time, and since negative pressure of a diaphragm chamber 26b is maintained, the fuel pressure can be sufficiently reduced more than injection fuel pressure. Since a chack valve 38 for opening under specifice pressure Pc or more is arranged in a fuel feedback passage 36, the fuel pressure in a delivery pipe 18 is maintained under the specified pressure Pc.
