Abstract
A fuel injector for delivering fuel to a combustion space comprises a valve needle which is movable within a bore provided in a nozzle body and which is engageable with a seating to control the supply of fuel from the bore. The injector further comprises a return flow passage for permitting fuel to escape from the bore to a low pressure drain upon initial movement of the valve needle away from its seating. The injector may include a cover member which defines, together with the nozzle body, a part of the return passage for fuel through which fuel flows, in use, to reduce the temperature of the nozzle body.
