What will happen after the compressor stepless gas volume adjustment is closed?

Volume flow decreases. When the piston moves to a specific position Cr50 (corresponding to the required air volume) during the load adjustment of the stepless air volume adjustment system, the actuator makes the forced external force pushing the valve plate disappear, the intake valve plate falls back to the valve seat and closes, and the residual gas in the cylinder begins to be compressed. When the compression process reaches the position and the gas reaches the rated exhaust pressure, the volume flow discharged by the exhaust valve decreases.
