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 1):
A valve, comprising:\n a first chamber configured for fluid communication with a first fuel line configured to flow fuel via a first opening in the first chamber; a second chamber configured for fluid communication with a second fuel line configured to flow fuel via a second opening in the second chamber and for fluid communication with a fuel storage tank via a third opening in the second chamber; a piston separating the first chamber from the second chamber; and a needle including a first end coupled directly to the piston and a second end including a tapered tip adapted to interface with the second opening, the needle extending through an entirety of the second chamber from the first end to the second end, the needle configured to control 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.
