Abstract
A fuel injector comprises a valve needle biased by a spring towards a seating. The spring engages a spring abutment member which is moveable with a piston member. The spring abutment member defines, with a member carried by the needle, a damping chamber which communicates through a restricted passage with a low pressure drain to damp movement of the needle relative to the piston member.
