ABSTRACT:
In a fuel injection system for an internal combustion engine having a high-pressure pump supplying fuel from a low pressure fuel supply conduit connected to the pump to a common high pressure fuel supply conduit for the injectors of the internal combustion engine via a high-pressure conduit extending between the high pressure pump and the common fuel supply conduit, the high-pressure conduit includes a non-return valve which, at the same time, is operable electromagnetically so as to be capable of maintaining the non-return valve open beyond the high-pressure pump delivery stroke for the release of fuel from the common fuel supply conduit under the control of the pump plunger and for rapid pressure relief by keeping the non-return valve open beyond a point at which the plunger opens the low-pressure fuel supply conduit connected to the pump.
