project a fragile liquid containing spherical unit which bursts upon impact with the intended target the regulator possesses a pressure balancing device a temperature compensating device and relief valve features the temperature compensator of the temperature compensating device is made of a synthetic compound material which expands and contracts at a rate that equals but is inverse to the rate of change caused by changes in the modulus of elasticity of a helical compression spring caused by a temperature differential the valve possesses a seal made of pressure activated material the outer diameter of the seal is mechanically captured the inner diameter of the seal is not constrained from moving into the cavity the application of pressure the initiates flow characteristics of the seal at the interface of the inner diameter of the seal and the outer diameter of the poppet this sealing technique has inherent lubricity is self healing is non temperature sensitive and is compatible with all noble gases used application_number US 2870598 A description fig1 shows a pneumatic valve fig2 4 show the pneumatic regulator the regulator comprises a series of connected passageways that extend from the first end of the regulator to the second end of the regulator and which are gated at various points by various components housed therein the regulator body 1 is generally externally cylindrical in shape with an interior that is.
