Hydraulic accumulator and fire suppression system

摘要

A hydraulic pressure accumulator has an interior chamber containing a fire-suppressing gas such as nitrogen. The fire-suppressing gas in the accumulator is fluidly connected to a thermal device, such as a valve with a thermal fuse or a controlled valve triggered by a thermal sensor. The thermal device is designed to open a fluid connection between the accumulator's interior chamber to ambient when the exterior temperature exceeds a determined safety threshold, thereby releasing the fire suppressing gas from the accumulator.
