摘要： 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).

摘要： A technology that can extend the life of a fuel injection device of an engine while maintaining its good responsiveness is provided. A fuel injection device 100 for an engine includes: a control rack 55 supported to be slidable in an axial direction and capable of adjusting of a fuel pressure-feed amount of a fuel pressure-feed mechanism unit 51, based on its slide-position relative to the axial direction; an actuator 40 capable of reciprocating its operating unit 41; and a link lever 20 swingably supported by a pivot shaft member 25 and configured to swing in association with reciprocation of the operating unit 41 of the actuator 40 thereby causing the control rack 55 to slide, wherein the fuel injection device includes an actuator-side connecting part 20A connecting an operating unit 41 of the actuator 40 to the link lever 20, and the actuator-side connecting part 20A is positioned on the same axis as the operating unit 41 of the actuator 40.
