AI Technical Summary

Technical Problem

Existing compressor devices and assemblies face challenges with high energy consumption, vibrations, pressure pulsations, and inefficient fluid evacuation, leading to noise and potential damage.

Method used

Incorporation of an adapter of acoustic impedance at the fluid duct outlet with an expansion chamber to modify acoustic impedance, smoothing pressure fluctuations and improving fluid evacuation efficiency.

Benefits of technology

Enhances energy efficiency by minimizing energy loss and reducing pressure pulsations, resulting in a smoother fluid flow and reduced noise, while maintaining operational integrity.
