Abstract
Systems, methods, and other embodiments described herein relate to a pressure relief valve that exhibits high flow rates at low pressures. The pressure relief valve includes a compressible hollow sleeve with an inner channel that is in fluid communication with an inflatable energy-absorbing body. The pressure relief valve also includes a dome-shaped sealing body that is affixed to a rigid substrate. The dome-shaped sealing body is pressed against and covers an outlet of the inner channel. Responsive to a gas pressure through the compressible hollow sleeve being greater than a threshold pressure, the dome-shaped sealing body deflects with snap-through buckling to expose the outlet through which the gas escapes.
