Eine duale Druckablassventil/Druckgleichgewichtsvorrichtung-Baugruppe (PRV/PED-Baugruppe) (200) wird als effizientere und kostengünstigere Alternative zu getrennten herkömmlichen PRV-Vorrichtungen (106) und PED-Vorrichtungen (108) bereitgestellt. Durch Kombinieren des PRV (106) und der PED (108) in einer einzigen Vorrichtung kann eine Anzahl von Teilen reduziert werden, wodurch Herstellungsressourcen der PRV-Vorrichtungen (106) und PED-Vorrichtungen (108) reduziert werden. Die offenbarte PRV/PED (200) beinhaltet ein Tellerventil (230), das an einem Ende eines Venturi-Rohrs (202) positioniert ist, durch das Entlüftungsgas ausgestoßen wird, wobei eine Membran (206) das Venturi-Rohr (202) umgibt. Druckbeaufschlagtes Entlüftungsgas, das bei den Zuständen eines thermischen Durchgehens aus der Umhüllung austritt, bewirkt, dass sich das Tellerventil (230) öffnet, wodurch die Membran (206) geschützt wird. Zusätzlich wird aufgrund einer Zunahme der Geschwindigkeit des Entlüftungsgases, wenn es durch einen Hals (603, 203) des Venturi-Rohrs (202) strömt, kühle Luft über die Membran (206) in das Entlüftungsgas gesaugt, wodurch eine Temperatur verringert wird, wenn es ausgestoßen wird.
