ABSTRACT:
A double ended piston assembly is maintained in a cocked position in a stepped piston chamber under the influence of pressurized sensor gas. Loss of pressure results in the pistons being driven to an actuating position wherein a puncture element carried thereby fractures a frangible disc in a high pressure gas container. High pressure actuating gas from the container is then routed by the device to operate a responsive device.
