Power conversion system utilizing multiple Stirling engine modules
A free piston Stirling engine module for a power conversion system is described in combination: a housing; a displacer cylinder within the housing and having an axis; first and second compression cylinders spaced apart on a common axis and located within the housing with the common axis transverse to the displacer cylinder axis; a displacer piston mounted for reciprocation in the displacer cylinder relative to an expansion space located beyond a first end of the displacer piston; first and second compression pistons mounted for reciprocation in the first and second compression cylinders respectively, the confronting ends of the pistons defining a compression space therebetween; annular cooling means disposed around the displacer cylinder; annular regenerator means disposed around the displacer cylinder between the cooling means and the expansion space; an engine working fluid; flow passage means to convey the working fluid between the compression and expansion spaces and through the regenerator means and the cooling means; means for introducing thermal energy into the expansion space to heat the working fluid therein; and separate means disposed proximate the ends of the compression pistons opposite the confronting ends for exerting restoring forces thereon.
