A pump/injector includes a high pressure pump which delivers fuel to an inwardly opening fuel injection nozzle. Also provided is a spill valve which is connected to the pumping chamber of the pump and through which the pumping chamber is filled with fuel from a source by way of a first non-return valve. Connected intermediate the spill valve and the non-return valve is a branch passage to the spring chamber of the nozzle and the pressure in the spring chamber when the spill valve is opened to terminate delivery of fuel is controlled by a valve.
