Abstract
An injection timing control device in a distributor-type fuel injection pump is provided with a servo valve for preventing vibration of the timer piston caused by a torque reaction force of the roller holder. A spring force control device holds the initial setting load of the timer spring urging the valve body of the servo valve at a predetermined value when the engine temperature exceeds a predetermined value, and reduces the initial setting load below the predetermined value when the engine temperature is below the predetermined value, to thereby obtain an injection timing advance at the start of the engine in a cold condition.
