<p>A pneumatic valve (50) and regulator (1), and more particularly to a pneumat ic valve and regulator used in a compressed gas powered gun system which is designed to project a fragile liquid-containing spherical unit which bursts upon impact with the intended target. The regulator (1) possesses a pressure balancing device (17, 18, 19), a temperature compensating device, and relief valve features. The temperature compensator (17) of the temperature compensating device is made of a synthetic compound material which expands a nd 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 (21) caused by a temperature differential. The valve possesses a seal (62) made o f 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 initiates the flow characteristics o f 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 se lf- healing, is non-temperature sensitive, and is compatible with all noble gase s used.</p> |
