摘要: In a plug-in pump fuel injection system of an internal combustion engine, wherein for each cylinder of the internal combustion engine a plug-in fuel injection pump is provided, each having a pump housing with a fuel feed channel and a fuel return channel, an annular plate provided with openings is arranged in a circumferential groove of the fuel return channel which extends around the pump housing of each plug-in pump and which forms a part of the fuel return channel of the respective plug-in fuel pump in order to inhibit the formation of pressure oscillations in the fuel return channel.
