The small piece on the bottom forces an internal cylinder to rise with pressure therefore allowing excess air to escape the system and bleeding off out of the top of the unit
These float-type air vents are designed to be installed vertically to vent air that is released from the water by being heated. These are recommended to be installed at the highest points in the system to properly eliminate any air within the system. Installation on every radiator may be overkill but it depends on your system.
