  • Publication number: 20240133469
    Abstract: This disclosure includes safety valves, vehicles and fueling stations having the same, and related methods. Some safety valves have a valve body defining a fluidic network including an inlet and an outlet, a piston disposed within and movable relative to the valve body between a first position in which the inlet is in fluid communication with the outlet and a second position in which fluid communication between the inlet and the outlet is prevented, and a heat-defeatable barrier that prevents movement of the piston to the second position. In some safety valves, the piston is biased toward the second position. In some safety valves, the piston includes a channel disposed between first and second ends of the piston, and when the piston is in the first position, the inlet is in fluid communication with the outlet via the channel.
