Abstract
A dual pressure relief valve (PRV)/pressure equilibrium device (PED) assembly is provided as a more efficient and less expensive alternative to separate, conventional PRV and PED devices. By combining the PRV and the PED into a single device, a number of parts may be reduced, thereby reducing a manufacturing resources of the PRV and PED devices. The disclosed PRV/PED includes a disc valve positioned at an end of a Venturi tube through which vent gas is expelled, where a membrane surrounds the Venturi tube. Pressurized vent gas exiting the enclosure under the thermal runaway conditions causes the disc valve to open, protecting the membrane. Additionally, due to an increase in speed of the vent gas as it passes a neck of the Venturi tube, cool air is drawn into the vent gas via the membrane, decreasing a temperature of the vent gas as it is expelled.
