Abstract:
1. A system for delivering a fuel from a tank to a fuel consuming device, said system comprising: a supply line configured to receive the fuel within the tank; a shut-off valve positioned within the supply line such that fuel from the tank flows into the shut-off valve through an inlet port and out of the shut-off valve through an outlet port, the shut-off valve including a valve seat biased by a spring that operates to open and close an opening between the inlet port and the outlet port of the shut-off valve to close and open the supply line, the spring being positioned within a bellows that defines a bellows chamber; and a control valve coupled in fluid communication with the shut-off valve through an input line and a control line, the input line being in fluid communication with the supply line through the inlet port of the shut-off valve, and the control line being in fluid communication with the bellows chamber through a control port in the shut-off valve; wherein the control valve is configured to open the shut-off valve by reducing the fuel pressure in the bellows chamber.
