The entry from the intermediate pressure hose into the second stage is sealed with a spring-loaded valve. The spring is just strong enough to hold back the intermediate pressure. The valve is also connected to a lever that touches the membrane of the second stage. When a diver inhales, the membrane is pulled inward. This action pushes the lever down. The movement of the lever opens the valve and air can flow into the second stage. When the diver stops inhaling, the membrane moves back to its original position and the second stage valve can close again.  2, record 1, English, - second%20stage

Pneumatic systems are often compared to hydraulic systems, but such comparisons can only hold true in general terms.... Control valves are... a necessary part of a typical pneumatic system.... The control valve consists of a lever with two lobes. [In the off position], a spring holds the left poppet closed so that compressed air entering the pressure port cannot flow to the brakes. [In the on position], one lobe of the lever holds the left poppet open and a spring closes the right poppet. Compressed air now flows around the opened left poppet, through a drilled passage, and into a chamber below the right poppet. Since the right poppet is closed, the high-pressure air flows out of the brake port and into the brake line to apply the brakes. To release the brakes, the control valve is returned to the off position.  3, record 2, English, - control%20valve
