Abstract
A fuel supply device in which a regulator pressurizes fuel fed to a fuel injector to adjust the fuel to a predetermined pressure according to an engine condition. The regulator has a piston in a housing to form a control chamber and a high pressure chamber therein. The high pressure chamber is communicated with the fuel injector and a pump chamber of a high pressure pump discharging a highly pressurized fuel. The control chamber is connected to a pressure source generating a high pressure according to an engine condition. The piston moves in response to the pressure in the control chamber to pressurize the fuel in the high pressure chamber.
