How does an automatic adjusting fog nozzle respond to pressure changes?

An automatic adjusting fog nozzle responds to pressure changes by altering the size of the opening. This design allows the nozzle to automatically adjust the pattern and flow of water based on the pressure supplied to it. When there is an increase or decrease in pressure, the nozzle configuration adapts to maintain an effective spray pattern and flow rate, ensuring optimal performance during firefighting operations.

By automatically adjusting the opening, it allows firefighters to get the correct amount of water to combat the fire without the need for manual intervention. This can be particularly beneficial in dynamic situations where conditions can change rapidly, making it essential to have a nozzle that responds fluidly to the environment without requiring additional adjustments from the firefighter.
