<p>The present invention relates to improvements in free piston Stirling engines and more particularly to a spring mounting system for the displace piston (12) of such an engine. A Stirling engine having a cylinder block (10) defining a cylinder (11) a displacer piston (12) located in said cylinder (11) having a heated end and a cooled end, and at least one spring mounting means provided to mount and centre the displacer piston (12) in the cylinder such that the displacer piston (12) is free to oscillate in the cylinder in response to a pressure differential across the displacer piston (12), or other perturbing force, the spring mounting means (17) being located at the cooled end of the cylinder (11) between the cylinder (11) and the piston (12) comprise at least two spring members arranged.</p> |
