    摘要: A fluid flow valve includes a movable valve piston positioned in a valve body, the valve piston configured to flow a fluid therethrough. A metering window is interactive with the movable valve piston to meter flow through the movable valve piston. A flow meter is positioned at the valve piston to measure a flow rate of fluid through the valve piston. A valve controller is operable connected to the flow meter and the movable valve piston to control position of the valve piston based on flow rate measured at the flow meter.

    摘要: A method of metering fuel with a fuel valve. The method includes arranging a spool within to a sleeve along an axis, wherein the spool includes four seal lands. The sleeve includes a fuel inlet aperture, a fuel outlet aperture, and a shutoff port. A first cavity and a second cavity are defined between the spool, the sleeve, and subsets of the seal lands. The fuel inlet port and the fuel outlet port abut one such cavity. Sliding the spool along the axis results in the fuel outlet aperture extending longitudinally beyond the second seal land in the upstream direction.

    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.
