ABSTRACT:
A fuel injection nozzle for supplying fuel to an internal combustion engine includes a nozzle holder which defines a chamber containing a spring which biases a fuel pressure actuated valve member to the closed position. Fuel leaks into the chamber in use and is allowed to escape from the chamber through a passage into a space defined between the holder and a surrounding sleeve. The sleeve carries a boss in which is formed an outlet communicating with the space. Fuel tight seals are provided between the sleeve and the boss.
