Abstract
The valve needle is held closed under the differential pressure of the fuel acting at the ends of the needle. In order to open the valve, a low pressure is applied to lift the control valve body. This allows the fuel to pass from the rear fuel chamber causing a pressure drop and a pressure differential to occur to unseat the needle valve.
