  • Mechanical fuse to seal pipes upon unintended rupture
    Patent number: 8316882
    Abstract: The present invention relates to a mechanical fuse to seal pipes upon unintended rupture. When a pressure difference between a first pressure and a second pressure in a pipe is below a pressure threshold, a first spring retains a flap in a first position allowing gaseous fuel to flow from a first portion to a second portion and when the pressure difference between the first pressure and the second pressure is not below the pressure threshold the flap moves to a second position preventing the gaseous fuel from flowing from the first portion to the second portion.
    Type: Grant
    Filed: September 15, 2011
    Date of Patent: November 27, 2012
    Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.
    Inventor: Andrea Leigh Lubawy
