Abstract
A fuel injection nozzle comprising a supply orifice through which fuel flows to a combustion space of an associated engine a resiliently loaded valve member which co-operates with a seating to prevent the flow of fuel through the supply orifice until the pressure of fuel applied to the valve member from an inlet attains a sufficiently high value, the mechanical connection between the valve member and the resilient means which loads the valve member being divided to define a variable volume chamber. Fuel is supplied to the chamber from the inlet and means is provided to limit the maximum volume of the chamber the arrangement being that fuel flowing through the inlet initially flows at a restricted rate through the supply orifice and when said chamber has attained its maximum volume the valve member is lifted to allow substantially unrestricted flow through the supply orifice.
