Abstract
An injector is described which comprises a valve needle engageable with a seating and biased towards the seating by a spring. The spring is located within a spring chamber and engages a moveable stop. The spring chamber communicates through a restricted passage with a low pressure drain. The injector further includes valve means which, when open, permits fuel to escape from the spring chamber at a higher rate.
