This chamber only has one thing to do: it provides a space for the shock wave to go to without producing the noise. This chamber is filled with air, as the name implies.
How does an air chamber in a water faucet work?
Since this dead-end pipe is installed in a way that it partly intersects water flow, the pipe also contains pocket of air. In practice, air in the chamber compresses temporarily under water pressure as you shut off a valve or faucet. Pressure is absorbed to minimize or even completely eliminate the banging noise.
