ABSTRACT:
Fuel injection apparatus for diesel engines includes an injection pump connected to an injector nozzle through a control device constituted by two calibrated and opposed non-return valves arranged to keep a residual pressure of a predetermined magnitude in the fuel supply passage to the injector between each injection cycle and the next. The two non-return valves are located downstream of the output of the pump and are preferably inserted in a body fixed to or forming part of the injector, or forming part of the delivery union of the pump.
