ABSTRACT:
A fuel injection nozzle comprises a poppet valve member having a head which is adapted to co-operate with a seating to control the flow of fuel through a spray orifice from an inlet. The poppet valve defines a first surface against which fuel under pressure can act from the inlet to lift the poppet valve from its seating and the orifice is formed in the valve member below the head so that when the poppet valve is closed the orifice is closed off from the combustion space of the engine. A second surface of annular form and facing into an annular chamber is provided to surround the poppet valve member and in communication with the inlet by way of a non-return valve, the pressure acting on the second surface to oppose the lifting of the head from the seat of the poppet valve.
