It changes the amount of resistance needed for the air to be released, ie if you are diving at depth you may feel that you are having to work hard to breath, if you adjust the lever it will become easier. In converse as you come to the surface if the reg starts to free flow you can adjust the lever to stop it. Happy bubble blowing :)
