摘要： A fuel injection system for internal combustion engines in which the control of the fuel injection valve member is controlled by controlling the pressure of a control chamber. The control chamber is either relieved by a 3/2-way control valve or made to communicate with a high-pressure fuel source. The control valve is designed such that the control valve has a valve body, which on both sides carries a valve sealing face, which cooperate with a first valve seat and second valve seat, respectively, and control the inflow of high pressure into or outflow thereof out of the control chamber. To vary the dynamics of the control events, the valve body, upstream of the second valve sealing face, has a throttle gap, and downstream of the first valve sealing face the valve body has a collar, between the collar and the throttle gap a pressure conduit leads away to the control valve, the inflow and outflow to and from which is thus varied.
