Compressing air using weight

  1. Feb 7, 2007 #1
    I want to compress air using the weight of a tank of water. Under the tank I propose some form of positive-displacement cylinder -perhaps a ram or spring return type cylinder.

    The tank will be supported in such a way so that it will move along with the cylinder. When filling up the tank the weight should cause the cylinder to compress the air. When I drain some of the water the tank will recede to its original position and draw in more air until the tank is refilled.

    My question is: What type of cylinder is best for this? And can you refer me to a site or vendor for the cylinder?

    Just do a google search on pneumatic cylinder or air cylinder.
