Abstract:
1. Pressure relief valve for venting a container of thermally conductive material which is for containing a fluid which expands and becomes pressurized upon the container being heated, comprising: a hollow member of relatively high thermal conductivity including a first end portion and a second end portion, said first end portion provided with a first internal surface and a second internal surface disposed inwardly of and extending outwardly from said first internal surface; a fusible member including a first end portion and a second end portion provided with an outwardly extending portion, said first end portion provided with friction enhancement means, said fusible member for being inserted into said hollow member through said second end portion thereof and said first end portion and said friction enhancement means of said fusible member for being forced into frictional engagement with said first internal surface of said hollow member to frictionally mount said fusible member in said hollow member, as said first end portion of said fusible member is being forced into frictional engagement with said first internal surface of said hollow member said outwardly extending portion of said second end portion of said fusible member for engaging said second internal surface of said hollow member to position said fusible member in said hollow member and to prevent said fusible member from being forced outwardly of said hollow member through said first end portion thereof as said fusible member is mounted frictionally to said hollow member; and said second end portion of said hollow member for being placed in mechanical and thermal engagement with the container.
