Concerning "auxiliary air reservoirs" these would never be used. They make them, we do sometimes use them on anti-freeze systems, but they must be UL Listed for fire protection service and that makes them expensive.

Auxiliary Reservoir When the auxiliary reservoir pressure has fallen to slightly less than the brake pipe pressure (e.g. 59 psi), the piston is pushed back to the left, closing the plug valve. By virtue of its smaller size, the brake cylinder pressure will reach around 25 psi for a 10 psi reduction in the auxiliary reservoir pressure.

6 FAQs about [Can the air pressure of the auxiliary air reservoir be adjusted ]
How does a auxiliary engine start at 30 bar pressure?
Refer to the figure above. Compressed air reaches the auxiliary engine at 30 bar pressure. The air pressure is reduced to 6 bar with a reduction valve. A safety valve is also fitted in the line after reducing valve to protect the air starting system components. Air then enters air starting valve (5) and wait there.
What are air reservoirs & how do they work?
By being able to to handle any sudden or unusually heavy demands in excess capacity r, air reservoirs can act as a buffer between your system and any fluctuation in pressure. Air reservoirs can also serve to dampen pulsations from discharge lines of your compressed air system, resulting in steadier pressure.
What is the compressed air system for auxiliary engines on ships?
Figure below shows the compressed air system for starting, stopping and fuel limiting for auxiliary engines on ships. Refer to the figure above. Compressed air reaches the auxiliary engine at 30 bar pressure. The air pressure is reduced to 6 bar with a reduction valve.
Why do you need a compressed air reservoir?
Air reservoirs can also serve to dampen pulsations from discharge lines of your compressed air system, resulting in steadier pressure. They can also help prevent frequent loading and unloading of compressed air systems, as well as precipitating any moisture or oil carryover within any compressed air generated.
Why is there no air pressure in a hydraulic accumulator?
If the hydraulic system pressure is normal while the engine-driven pump is running, but there is no pressure after the engine has been shut off, it indicates no air pressure in the accumulator. The purpose of restrictors in hydraulic systems is to control the rate of movement of hydraulically operated mechanisms.
How do auxiliary reservoirs work?
reservoir is controlled by the triple valve. application of brakes. metal. On both the ends of the reservoir, flanges are provided for pipe connection. One end of the auxiliary reservoir is connected to the brake pipe through the distributor valve. Auxiliary reservoir is charged through the brake pipe.
