ABSTRACT:
A fuel injection nozzle including in assembly the following essential components: a nozzle body; a needle valve and a control member. Two stages of injection are produced both of which are controlled by the needle valve. The control member serves during the second stage of injection and cooperates with the needle valve to effect this stage of injection. For this purpose the control member fits, in a radially sealed manner, within a blind bore formed in the needle valve and defines a channel through which fuel flows under the control of the needle valve. The channel in turn is connected with injection opens for the injection of fuel during the second stage of injection.
