Abstract:
Various methods and systems are provided for a pressure relief valve of a fuel system. In one example, a valve includes a first chamber in fluid communication with a first fuel line, a second chamber in fluid communication with a second fuel line and in fluid communication with a fuel storage tank, a piston separating the first chamber from the second chamber, and a needle coupled to the piston and controlling a flow passage between the second fuel line and the second chamber, where the piston and needle are sized such that a force applied on the piston by the first chamber parallel to an axis of movement of the piston maintains the needle in a closed position when the first fuel line flows fuel at a first pressure and the second fuel line flows fuel at a second pressure, the second pressure greater than the first pressure.

Claim (Index 16):
The system of  claim 15 , wherein:\n a surface area of the piston exposed to fuel in the first chamber and a surface area of the needle exposed to fuel in the flow passage are each sized such that the force applied by the fuel at the first pressure on the piston maintains the needle in a first position where the flow passage is blocked, to maintain the pressure relief valve in the closed position, even when the fuel at the second pressure or the third pressure is supplied to the pressure relief valve.
