Soap Dispenser 1 pcs

Initial press (priming): When you first press down on the actuator (the top part), a piston moves down to compress a spring. This creates upward air pressure that lifts a small ball valve, pulling liquid soap from the bottle and into the pump housing. Release: When you release the actuator, the spring pushes the piston back up. The ball valve returns to its original position, sealing the entry to the bottle and preventing soap from flowing back down. Second press (dispensing): Pressing the actuator a second time pushes the liquid that has been drawn into the housing up through a small hole and out of the nozzle
