Vitale, N G

This patent describes a Free Piston Stirling cycle system of the type including a power piston, a displacer having a diameter, an expansion space, a compression space, a gas spring space, and means coupling the displacer with the gas spring. This patent describes improvement in a relative gas spring means arranged and constructed for generating a force to impart movement to the displacer by the relative motion between the displacer and the power piston, the gas spring piston having a diameter and being arranged and constructed so that the ratio of the diameter of the gas spring piston to the diameter of the displacer is at lease 0.50.
