Distributor type fuel injection pump |
摘要 |
In a distributor type fuel injection pump including a load-responsive pressure adjusting device which is responsive to engine loads for allowing drainage of part of the fuel in the suction chamber of the pump into a zone under lower pressure in the pump when the engine is operated within a predetermined load range, a pressure setting valve is provided in a drainage passage forming part of the pressure adjusting device, which is adapted to open at a predetermined pressure. The pressure setting valve enables establishment of necessary fuel pressure for normal actuation of a fuel injection timing control device provided in the pump within a low engine speed (rpm) range even during operation of the pressure adjusting device.
