Abstract
A cylinder has spaced ends and a piston is slidably and turnably received in this cylinder. An opening is provided through which a pressure fluid is admitted into the cylinder at one end, and an arrangement is provided which is connected with the piston so that counter-weights can act upon the piston in a sense opposite to the pressure exerted by the pressure fluid. The arrangement includes a ball and socket structure.
