Abstract
A fuel injector comprises a valve needle spring biased towards a seating. The valve needle defines a thrust surface orientated such that the application of fuel under pressure thereto applies a force to the needle urging the needle away from the seating. A valve is provided to control the supply of fuel to the thrust surface.
