Abstract
A shut-off valve arrangement for a gas turbine engine fuel supply system includes a shut-off valve in a fuel supply line to the engine, and a drain valve communicating with said supply line downstream of the shut-off valve. Said shut-off valve and drain valve are responsive to a servo pressure signal which is applied through flow restrictors such that the drain valve shuts before the shut-off valve, but opens after the shut-off valve.
