Can increasing the pressure of the gas entering the compressor increase the air volume?

Can increasing the pressure of the carbon dioxide gas at the inlet of a piston compressor increase the air delivery volume? What is the principle?
Yes, when the pressure-volume (compressor chamber volume) remains constant and the inlet pressure increases, the amount of air compressed rises. . . But it must be kept below the maximum pressure at the inlet. . .
As pressure increases, density rises as well, and the amount of air intake per unit time increases, but this must remain within the limits permitted by the unit
It is possible to do this by increasing the inlet pressure; with the outlet pressure remaining unchanged, this is equivalent to reducing the compression ratio. As a result, the exhaust temperature drops significantly, which facilitates the long-term stable operation of the compressor. It also increases the volume of exhaust gas
The volume of the compression cylinder is fixed; the clearance in the compression cylinder can be adjusted
It’s possible, but it cannot exceed the maximum intake pressure; this is equivalent to reducing the compression ratio
