Sometimes I find a tool that is so cool that I just want one to play with.

This firmly falls into that category. It's designed to allow changing of the core of schrader valves while under pressure or vacuum while reducing the loss of gas or intake of air to a minimum.

Because China has a huge infrastructure, there are some very cool tools available cheaply from online sites like eBay. This is one of them. It's a schrader valve core changer, but is designed to change the cores under pressure/vacuum in active refrigeration and air conditioning systems. Note that this tool is not intended for changing schrader inserts on car tyres/tires. I'm not sure what size of port they use. This tool accommodates 1/4" and 5/16" valves. I'm guessing the extra side port might be for pulling vacuum or injecting refrigerant with the core removed for speed.
