Abstract: PURPOSE:To permit to inject the fuel with a predetermined pressure even in the low-speed and low-load operating area of an engine by a method wherein the valve opening pressure and the amount of lift of a needle valve are controlled by utilizing leak fuel. CONSTITUTION:The high pressure fuel, sent from a fuel injection pump 2 with pressure, applies the pressure of the fuel to the needle valve 14 in an oil reservoir 15 into the direction of lift of the valve 14.
