Apparatus for elimination of transient pressure spikes on stiff fluid systems

An apparatus for reducing transient pressure spikes in a fuel line of a turbine system, the turbine system having a shut-off valve, the apparatus comprising:

• a body having first, second, and third chambers, the first chamber coupled to the fuel line upstream of the shut-off valve and the second chamber coupled to the fuel line downstream of the shut-off valve, the third chamber adjacent to and coupleable with the first chamber;
• a biasing member within the body;
• and
• a moveable separation member within the body, the moveable separation member biased toward the first chamber by the biasing member and separating the first chamber from the second chamber when the shut-off valve is open, the moveable separation member adapted to expand the first chamber, compress the biasing member, and place the first chamber and the third chamber in fluid communication when the shut-off valve is closed, at least one of the expanding first chamber and the third chamber accumulating fuel when the shut-off valve is closed such that the transient pressure spikes are reduced and unlikely to cause damage to the turbine system.

• a biasing member within the body;
• and
• a moveable separation member within the body, the moveable separation member biased toward the first chamber by the biasing member and separating the first chamber from the second chamber, the moveable separation member restricting flow between the first and third chambers when the shut-off valve is open, the moveable separation member adapted to expand the first chamber, compress the biasing member, and place the first chamber and the third chamber in fluid communication when the shut-off valve is closed, the expanded first chamber accumulating fuel and the third chamber evacuating the fuel through the return line such that the transient pressure spikes are reduced and unlikely to cause damage to the turbine system.
