Abstract
A valve actuated in response to a drop in fuel pressure across a fuel supply valve that will drain the fuel from a fuel line but not leak when exposed to high fuel pressures during normal operation. The dump valve is particularly applicable to the draining of fuel from a gas turbine engine fuel nozzle line after shutoff of the engine fuel supply valve.
