Abstract
A fluid flow system for supplying fuel to an engine, the system including a fluid flow valve having a valve element movable alternatively to a first operative position in which a relatively low fluid flow rate is permitted through the valve, for achieving a normal gradual shut-off of fuel supply, and a second operative position in which a relatively high fluid flow rate is permitted through the valve, for achieving a rapid emergency shut-off of fuel supply. Also disclosed is a fluid flow valve for use in the system. The invention has application in aircraft gas turbine engines.
