Abstract
In a distributor type fuel injection pump for use with an internal combustion engine, which is equipped with an injection timing control device operable in response to oil pressure within a pressure oil chamber, which is variable as a function of the rotational speed of the engine, an overflow valve is provided, which is closed at the start of the engine when the oil pressure within the pressure oil chamber is low, and is opened during subsequent operation of the engine to cause escape of the above oil pressure to a lower pressure zone in the pump, to thereby cause the above injection timing control device to obtain an advance in the fuel injection timing.
