Abstract
A fluid pressure chamber is formed in a fuel injection valve, in which a piston connected to a nozzle needle is reciprocally disposed. The pressure chamber is supplied with fluid under pressure from a fluid pump through a check valve. The pressure chamber is also connected with an orifice. When a fuel is distributed from a fuel injection pump under pressure and supplied to the injection valve, the nozzle needle is lifted by the distributed fuel under pressure. When the nozzle needle is lifted, the fluid in the pressure chamber is compressed for causing a fluid pressure applied to the piston in a valve closing direction, whereby the starting of the fuel injection becomes gentle, decreasing combustion noises.
