Description

ABSTRACT:
A fuel supply system for an accumulator fuel injection system designed to inject fuel, as stored in an accumulator, into an internal combustion engine through a fuel injector The fuel supply system includes a feed pump working to pump the fuel out of a fuel tank and a fuel filter disposed between the feed pump and a high-pressure pump working to deliver the fuel to the accumulator. The fuel supply system also includes a return path and a control valve. When the pressure of the fuel between the fuel filter and the flow rate control valve exceeds a first set pressure, the control valve opens the return path to return the fuel from downstream to upstream of the feed pump to keep the pressure of fuel supplied to the flow rate control valve below the first set pressure, thereby controlling the flow rate of the fuel passing through the fuel filter.
