In a diesel fuel injection nozzle, a separating assembly which separates high and low pressure circuits comprises a member having a through bore, in which a connecting pin is located to transfer hydraulic/mechanical force on energisation of an actuator, to a nozzle needle, via an inverter/amplifier assembly, wherein a sleeve is provided around the pin, such that radial forces from high pressure fuel act upon the sleeve, thereby reducing a pre-determined clearance between the pin and sleeve, thereby reducing leakage of fuel between the high and low pressure circuits via the separating assembly. |
