Abstract
An apparatus for reducing pressure spikes in a fuel line having a shut-off valve is provided. The apparatus comprises a body housing a biasing member and a moveable separation member. The body has first, second, and third chambers. The first and second chambers are coupled to upstream and downstream sides of the fuel line, respectively. The third chamber is coupled to a return line. When the shut-off valve is open, the separation member is biased toward the first chamber and separates the first and second chambers. When the shut-off valve is closed, the separation member expands the first chamber and places the first chamber and the third chamber in fluid communication once the separation member has gained a significant speed. The expanded first chamber accumulates fuel and the third chamber accumulates and vents the fuel such that transient pressure spikes are reduced and unlikely to damage a turbine system.
