ABSTRACT:
A fuel injection nozzle for supplying fuel to an internal combustion engine includes a fuel pressure actuated valve member slidable within a bore. The working clearance defined between the co-operating surfaces of the valve member and bore at one end communicates in use with a source of fuel under pressure which may not have adequate lubricity to provide proper lubrication of the surfaces. A groove is defined between the surfaces and communicates with a drain and the other end of the working clearance communicates in use with a source of lubricating medium.
