Abstract
The fuel control system supplies an engine via a pressure raising and shut-off valve. The valve is operated by a piston and cylinder arrangement. A shut-off motor controls the fuel pressure in a control line of a rapid shut-down valve. The rapid shut-down valve is operable to connect the cylinder to a high pressure fuel supply (HPf) via relatively large diameter pipes. The shut-off motor also controls the fuel pressure in a second control line connected directly to the cylinder. The shut-off motor is operable to supply high pressure fuel to the cylinder via the second control line. The rate of fuel flow into the cylinder via the second control line is less than that via the rapid shut-down valve so as to provide a normal rate of shut-down.
