ABSTRACT:
A mechanical force amplifier is disclosed including a gas-containing cylinder having one fixed end and one movable end determined by the position of an output power piston. A cold temperature zone and a hot temperature zone are maintained along the axis of the cylinder, the cold zone being adjacent the fixed end and the hot zone being adjacent the movable end. The power piston is resiliently urged toward the fixed end so as to compress the gas.
A displacement piston is positionable along the axis of the cylinder within the cold zone and the hot zone and is designed to allow the gas to flow around it as the piston is moved. The displacement piston and the power piston are completely uncoupled from movement with each other except through the gas.
