    en.wikipedia.org/wiki/Pneumatics

    A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators.

    en.wikipedia.org/wiki/Pneumatic_cylinder

    Pneumatic cylinder, also known as air cylinder, is a mechanical device which uses the power of compressed gas to produce a force in a reciprocating linear motion. [ 1 ] : 85 Like in a hydraulic cylinder , something forces a piston to move in the desired direction.

    en.wikipedia.org/wiki/Schrader_valve

    Schrader valves are used in a wide variety of compressed gas and pressurized liquid applications such as small torch and grill cylinders, and air shocks. Schrader valves are also viewed as more complex (requiring two seals over one). They weigh 4 to 5 grams (0.14 to 0.18 oz) more than Presta valves. [10]

    en.wikipedia.org/wiki/Dry_gas_seal

    The first dry gas seal for a compressor was patented by Kaydon Ring & Seal in 1951 when it was known as Koppers Corporation. Field applications of dry gas seal designs were completed in 1952. The original patent was for Kaydon's "Tapered Ramp" lift geometry, a constant diameter / variable depth dynamic lift design.

  6. Hydraulic seal - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_seal

    A static hydraulic seal is located in a groove and sees no movement - only sealing within its confined space, acting like a gasket. To achieve this the gasket should be under pressure. The pressure is applied by tightening of the bolts. Examples of static seals include O-rings, flange seals, and cover seals. Dynamic

    The cylinder seals themselves are typically made from hardstones, and some are a form of engraved gem.They may also use glass or ceramics, like Egyptian faience.Many varieties of material such as hematite, obsidian, steatite, amethyst, lapis lazuli and carnelian were used to make cylinder seals.
