Stirling cycle engine
This patent describes a Stirling cycle type engine including a cylinder having a cylinder cap, a power piston and a displacer piston both slidably carried within the cylinder. The displacer piston divides the interior of the cylinder into two chambers one of which is located between the power piston and displacer piston. The two chambers are connected to one another through cooler means for cooling a fluid in the apparatus. A regenerator means for absorbing heat from a fluid and heater means for heating a fluid in the apparatus, the improvement comprises: the cooler means comprising a cooling tank formed around the lower portion of the cylinder and cooler elements. The cooler elements define cooler flow passageways within the cooling tank, and means for circulating a cooling fluid within the cooler means; the regenerator means comprising regenerator elements defining regenerator flow passageways; the heater means comprising heater elements defining heater flow passageways; the cooler flow passageways, the heater flow passageways and the regenerator flow passageways serially connected with one another; the cooler means and the regenerator means being disposed on a common peripheral side of the cylinder and vertically aligned therewith to thereby reduce the radial extension of the engine. The regenerator means extending vertically and parallel to but spaced from the outer peripheral wall of the cylinder, the regenerator means comprising a cylinderical tube, the upper end of the tube communicating with the heater means.
