  • Impact sensitive safety-relief system for tank cars
    Patent number: 4126151
    Abstract: A frangible member isolates a rupture disc from a pressurized fluid system. Under abnormal conditions such as might be encountered in a crash or derailment, the frangible member breaks and thereby permits direct contact of the rupture disc with the fluid system. If the pressure is sufficient, this causes the rupturing of the disc and the venting of the fluid system down to atmospheric pressure.
