Abstract
A control valve for an injector comprising a valve body having of a control chamber connected to a drain conduit via a hole terminating at a flat surface of the valve body. The plunger of the valve consists of a plate housed in a seat, the bottom wall of which arrests the travel of the plate after a travel 'b'. This is controlled by the armature of an electromagnet, which armature presents a rod arrested directly by an adjustable stop after traveling a distance 'a' greater than travel 'b'. The opening and closing time of the valve is therefore unaffected by wear on the stop of the armature. The rod of the armature is in one piece with a stem activating the plate, and with a threaded portion screwed to the armature.
