Abstract : The patent relates to an apparatus for rupturing a seal and routing air pressure to a pressure or pressure-differential sensing device. A ported knife-edge gate valve is slidably positioned within an elongated chamber in a casing and is biased by an energy source from a first inactive position to a second actuated position through a sealed diaphragm into an air stream for creating a new path for air flow. Detent means prevent operation of the device until the detent is released by a lanyard, arming wire or other release mechanism. Multiple air passages within the valve connect the air flow to a differential pressure sensing device. Movement of the valve may also enable activation or may activate other associated mechanisms. One application suggested applies to ordnance fuzes.
