Abstract:
Venting and sealing apparatus to control the barometric pressure of air surrounding the guidance apparatus within a missile is shown to consist of: (a) a metallic valve body made up of a cup with a perforate bottom and a lip attached to the shell of the missile surrounding an opening formed through the shells; and (b) a plug within the cup, the position of such plug relative to the perforate bottom being controlled by the relationship between the barometric pressure of the atmosphere outside the missile and the barometric pressure of the air surrounding the guidance apparatus.
