Abstract

The armature of a solenoid actuated fuel injector comprises an upper armature part (7) and a lower armature part (8), each armature part being independently moveably guided on the pintle (1). Biasing means (11) are provided between the upper and lower armature parts (7,8) biasing the upper and lower armature parts away from one another, the biasing means (11) biasing the upper armature part (7) towards an upper stop (9) provided on the pintle (1) and biasing the lower armature part (8) towards a lower stop (10) provided on the pintle (1).
