Abstract
A diaphragm pressure regulator comprising a housing having first and second sections. The first section 1a has a cavity or vacuum space, and a wave spring is disposed in the vacuum space, a load distributor is disposed adjacent to the wave spring, and a diaphragm seals the cavity and secures the wave spring and load distributor in the cavity. The second section of the housing comprises a movable and sealable vent stem that moves in response to movement of the diaphragm, and a vent opening for venting the interior of the second section of the housing to external pressure in response to motion of the diaphragm. The diaphragm pressure regulator may be preferentially used in an upper atmospheric system that needs to maintain a specified pressure, but requires venting capabilities. Such systems include missile systems that fly into the upper atmosphere.
