A shock actuated valve including a first structure mounted to swing about a first axis and which is releasably retained by a first latch in a first position, with the latch being automatically releasable when the device is subjected to earthquake forces or other shock forces, and a second structure

A shock actuated valve including a first structure mounted to swing about a first axis and which is releasably retained by a first latch in a first position, with the latch being automatically releasable when the device is subjected to earthquake forces or other shock forces, and a second structure including a valve and which is mounted to swing about a second axis and is releasably retained in an open valve position by a second latch controlled by the first swinging structure. When shock forces cause release of said first structure for swinging movement from its reset position, such swinging movement automatically releases the second structure and its valve for spring urged swinging movement in a direction closing the valve.
