Abstract
A valve controlled by an electromagnetic metering valve comprising a head ving a control chamber, a supply conduit, and a drain conduit. The head also presents a cavity communicating with the supply conduit and in which a portion of the moving element for closing the injection orifice slides in such a manner as to choke the supply conduit during injection. The supply conduit communicates with a receiving chamber located between a seat in the body of the valve and the outer surface of an appendix on the head; and the moving element is pushed into the closed position by the combined action of the pressure at each end, and a spring located close to the injection chamber.
