FUEL METERING VALVE AND METHOD OF MANAGING FUEL IN A METERING VALVE

摘要

A fuel metering valve includes a main flow path extending axially between an inlet and an outlet. Also included is a plunger disposed around a portion of a plunger guide, the plunger and the plunger guide configured to translate between an open position and a closed position to selectively distribute a fuel flowing through the main flow path to the outlet of the fuel metering valve. Further included is a solenoid coil disposed between a solenoid outer body and a solenoid inner body, the solenoid coil configured to magnetically attract the plunger to the open position. Yet further included is a secondary flow path for routing a stagnant volume of fuel upon translation of the plunger from the closed position to the open position.
