2. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   A typical nominal regulated gauge pressure from a medical oxygen regulator is 3.4 bars (50 psi), for an absolute pressure of approximately 4.4 bar and a pressure ratio of about 4.4 without back pressure, so they will have choked flow in the metering orifices for a downstream (outlet) pressure of up to about 2.3 bar absolute.

3. 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 ...

4. Diving regulator - Wikipedia

   en.wikipedia.org/wiki/Diving_regulator

   A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.

5. Gas cylinder - Wikipedia

   en.wikipedia.org/wiki/Gas_cylinder

   This attachment typically has a pressure regulator with upstream (inlet) and downstream (outlet) pressure gauges and a further downstream needle valve and outlet connection. For gases that remain gaseous under ambient storage conditions, the upstream pressure gauge can be used to estimate how much gas is left in the cylinder according to pressure.
