Second stage demand breathing regulator. |
摘要 |
<p>A second stage demand regulator is disclosed which as a regulator body with a spring loaded poppet valve mounted therein. A diaphragm mounted in said regulator body responds to pressure differentials to provide demand breathing gas to a user in communication with the regulator. The demand valving function is provided by the spring loaded poppet having a lever in contact with the poppet and the diaphragm. Upon acutation of the diaphragm, a greater mechanical advantage is initially provided to the lever through a point of contact with an operating surface that is closer to the axis of rotation than a second point of contact. <IMAGE></p> |
