  2. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...

  3. Breathing performance of regulators - Wikipedia

    en.wikipedia.org/wiki/Breathing_performance_of...

    The formation of ice is not considered as long as the ice does not degrade the breathing performance beyond minimum performance requirements, and it does not free-flow. [9] The CE test uses an air supply starting at the highest pressure the regulator is rated for and is breathed for five minutes at 62.5 lpm using an exhalation temperature of 28 ...

  4. Regulator (automatic control) - Wikipedia

    en.wikipedia.org/wiki/Regulator_(automatic_control)

    Examples are a voltage regulator (which can be a transformer whose voltage ratio of transformation can be adjusted, or an electronic circuit that produces a defined voltage), a pressure regulator, such as a diving regulator, which maintains its output at a fixed pressure lower than its input, and a fuel regulator (which controls the supply of ...

  5. Diving cylinder - Wikipedia

    en.wikipedia.org/wiki/Diving_cylinder

    A diving cylinder or diving gas cylinder is a gas cylinder used to store and transport high pressure gas used in diving operations.This may be breathing gas used with a scuba set, in which case the cylinder may also be referred to as a scuba cylinder, scuba tank or diving tank.

  6. Engine–generator - Wikipedia

    en.wikipedia.org/wiki/Engine–generator

    In addition to the engine and generator, engine–generators generally include a fuel supply, a constant engine speed regulator (governor) in diesel and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may ...

  7. Oxygen therapy - Wikipedia

    en.wikipedia.org/wiki/Oxygen_therapy

    A small portable M6 (B) cylinder holds 164 or 170 litres (5.8 or 6.0 cu ft) and weighs about 1.3 to 1.6 kilograms (2.9 to 3.5 lb). [62] These tanks can last 4–6 hours with a conserving regulator, [clarification needed] which adjust flow based on a person's breathing rate. Conserving regulators may not be effective for patients who breathe ...

  8. Oxygen concentrator - Wikipedia

    en.wikipedia.org/wiki/Oxygen_concentrator

    An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .

  9. Gas-generator cycle - Wikipedia

    en.wikipedia.org/wiki/Gas-generator_cycle

    The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost.
