摘要：
A fuel injection device for a diesel engine or the like confines the fuel injection pressure to a predetermined range. Fuel is fed under pressure from a fuel supply source to a high pressure chamber to develop a pressure therein. An injection nozzle is mounted on a nozzle holder and has a nozzle hole for injection fuel in response to the pressure in the high pressure chamber. The nozzle holder has thereinside a low pressure chamber which communicates to the outside. An injection rate control valve is mounted in the nozzle holder for delivering fuel to the low pressure chamber on the elevation of the fuel pressure communicated to the high pressure chamber beyond a predetermined value.
