Explaining the Internal Mechanism

What happens here

The demonstrator explains the internal mechanism that enables the 'no-pump' feature. The sprayer works by using town water pressure (between 60 and 80 PSI) to inflate an internal bladder via a Schrader valve. This expanded bladder then applies continuous air pressure to the liquid inside the tank, allowing for sustained, full-pressure spraying without manual pumping. This is contrasted with traditional pump sprayers, which might require 125 pumps and 20 minutes to achieve the same result.

Goal: Understand the technology behind the 'no-pump' functionality.
