Abstract
A fuel injection system for a compression ignition engine includes a high pressure fuel pump, an injection nozzle and valve means adjacent the pump. The valve means includes a first valve member spring biased to a closed position and a second valve also spring biased to a closed position. The first valve member defines an absorbing chamber which following the closure of the second valve member upon cessation of fuel flow has the pressure therein reduced. A valve element can open the absorbing chamber to the pipeline connecting the valve means to the nozzle, when a reflected pressure wave travels towards the pump from the nozzle, the reflected pressure wave being absorbed in the chamber.
