ABSTRACT:
A fuel injection nozzle unit has an inwardly opening valve member which can be moved by fuel pressure in a chamber connected to a fuel inlet to allow fuel flow through an outlet orifice. In order to circulate fuel through the chamber a passage leads therefrom to a fuel outlet. A restrictor is located in the passage and the valve member acts to prevent flow through the passage when it is open to allow fuel flow through the outlet orifice.
