Abstract:
1. An apparatus for reducing transient pressure spikes in a fuel line of a turbine system, the turbine system having a shut-off valve and a relief valve, the relief valve upstream of the shut-off valve in the fuel line, the apparatus comprising: a body forming a first chamber and a second chamber, the first chamber coupled to the fuel line upstream of the shut-off valve, the second chamber coupled to the fuel line downstream of the shut-off valve; a biasing member within the body; and a moveable separation member within the body, the moveable separation member forcibly biased toward the first chamber by the biasing member and separating the first and second chambers when the shut-off valve is open, the moveable separation member adapted to expand the first chamber and compress the biasing member when the shut-off valve is closed, the expanding first chamber accumulating fuel while the relief valve is opening such that the transient pressure spikes are reduced and unlikely to cause damage to the turbine system.
