Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fluid flow valve comprising: a movable valve piston reciprocally disposed in a valve housing, the valve piston including a passage configured to flow a fluid therethrough; a metering window interactive with the movable valve piston to meter flow through the valve piston; a flow meter disposed in the passage to measure a flow rate of the fluid through the valve piston; and a valve controller operably connected to the flow meter and the movable v…
