FUEL INJECTION PUMP

There is provided a fuel injection pump that enables white smoke in exhaust gas to be significantly reduced. A fuel injection pump (100) delivers, at high pressure, a fuel to be injected into a combustion chamber of a diesel engine and includes a delivery valve (10) disposed in the middle of a path for pressure-feeding the fuel from a plunger (104) to a fuel injection nozzle. A damping valve (17) is disposed on the downstream side of the delivery valve (10). The damping valve (17) includes a valve element (15) which has an orifice (15a) formed on an axial part thereof and is biased downward (toward the upstream side) by a damping valve spring (18) and a receiving element (16) which has a passage hole (16a) formed on an axial part thereof and abuts against the valve element (15). A recess (15b) which communicates with the passage hole (16a) is formed on a face of the valve element (15), the face facing the receiving element (16).
