Abstract:
A fuel injector comprising:a first body and a second body; a capnut that is in threaded engagement with the first body and has a shoulder for abutting against the second body to hold said first and second bodies together; a locating pin for fixing the angular position of said first and second bodies relative to each other; an insulating layer for electrically insulating said first body from said second body, said insulating layer being deposited in such a way that electrical contact is prevented between the locating pin and at least one of said bodies; a channel arranged in the first and second bodies; a reciprocating needle moveable within said first and second bodies for opening and closing the channel; wherein said first and second bodies are not electrically connected when said needle is in an open position and wherein said first and second bodies are electrically connected when the needle is in the closed position; an anti-friction layer body is placed between said shoulder and said second body thereby reducing the torque transmitted to the locating pin when the cap nut is tightened.
