Abstract
Embodiments of a force generating element that can broaden the application of valves and, in particular, pilot-operated valves to include applications that have extreme operating temperatures. These improvements forgo use of o-rings (and like elastomeric devices) in lieu of more durable and robust seals (e.g., metal-to-metal contact). Rather, as discussed more below, the valves incorporate a force generating element that ensures contact between components to form appropriate seals that allow the cylinder to maintain pressure, despite dimensional changes in the structure of the valve.
