  2. Gas lift - Wikipedia

    en.wikipedia.org/wiki/Gas_lift

    The gas-lift mandrel is a device installed in the tubing string of a gas-lift well onto which or into which a gas-lift valve is fitted. There are two common types of mandrels. In a conventional gas-lift mandrel, a gas-lift valve is installed as the tubing is placed in the well. Thus, to replace or repair the valve, the tubing string must be pulled.

    The solenoid valve regulates the amount of oil pumped by the cam action to either the valve or a bypass reservoir. When pressurized, the hydraulic line behaves like a solid body and transmits the lift schedule imparted by the intake cam directly to the intake valve. When the solenoid is disengaged, a spring takes over valve actuation duties.

    en.wikipedia.org/wiki/Cameron_Ram-type_Blowout...

    The blowout preventer is a T-shaped coupling that is screwed onto the top of the casing. It has a passage through the coupling for the drill string. There is a ram with a concave, semi-circular face in each arm of the tee. Each ram is moved in or out by turning its valve stem, which extends beyond the coupling. The ends of the stems are squared ...

    Desmodromic valve systems are first mentioned in patents in 1896 by Gustav Mees. [ citation needed ] Austin's marine engine of 1910 produced 300 bhp and was installed in a speedboat called "Irene I"; its all-aluminium, twin-overhead-valve engine had twin magnetos, twin carburettors and desmodromic valves.
