    Abstract: A fluid metering valve includes a flow circuit defined by the valve and a valve member disposed in the flow circuit, the valve member having a sealing portion and configured to be moved by a solenoid between a closed position and one or more open positions. The valve includes a seat member defining one or more fluid outlets, the seat member configured to receive the sealing portion in the closed position to seal the fluid outlets, and an internal porting path defined through the sealing portion that is configured to fluidly connect a downstream side of the sealing portion with an upstream portion of the flow circuit in the closed position to reduce the effective pressure area of the valve member.

    Abstract: 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.
