Product Description
The Upstroke (Priming for the Next Dose)
-
You release the actuator.
-
The compressed spring pushes the piston back up to its original position.
-
This upward movement creates a vacuum (negative pressure) inside the chamber.
-
The inlet valve opens due to this vacuum.
-
The vacuum simultaneously draws two things into the chamber:
-
Liquid from the bottle (via the dip tube).
-
Air from the outside atmosphere (via a dedicated air inlet channel, often built into the housing or piston).
-
-
The chamber is now refilled with a precise ratio of liquid and air, ready for the next press.
This cycle repeats with every pump, ensuring a consistent dose of foam each time.
