Abstract
Official abstract text for this publication.
A fill control system includes a fuel storage vessel, a fuel inlet in fluid communication with the fuel storage vessel to provide fluid communication between a fuel source and the fuel storage vessel, and a fill control valve disposed between and in fluid communication with the fuel inlet and the fuel storage vessel, an actuation of the fill control valve causing a pressure level upstream thereof which emulates a full condition of the fuel storage vessel.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a filling operation comprising the steps of: actuating a fill control valve to generate a pressure level upstream of the fill control valve, the pressure level emulating a full condition of a fuel storage vessel, the fill control valve including a bleed path formed therein, the bleed path configured to provide a pre-determined minimum flow rate of fluid therethrough wherein the pressure level upstream is accomplished without a fluid-t…
