Dale Evan Kiikka is a notable inventor based in Athens, OH (US), recognized for his contributions to the field of Stirling cycle machinery. With a total of four patents to his name, Kiikka has made significant advancements that enhance the efficiency and functionality of these machines.
Latest Patents
One of Kiikka's latest patents is the "Displacer and seal assembly for Stirling cycle machines." This invention addresses the issue of gas leakage and friction force in Stirling cycle machines. By preventing gas leakage between the seal and the cylinder's inner surface, the invention allows for a more relaxed manufacturing tolerance for the displacer. The design minimizes the need for precise finishing of the radial clearance, ensuring that gas leakage is effectively prevented without excessive pressure on the seal. Additionally, the friction force generated is significantly reduced, allowing for smooth reciprocation of the displacer. Another notable patent is the "Porous restrictor for gas bearing," which is particularly useful in gas bearings for free-piston Stirling cycle machinery. This invention utilizes porous strip material along with a backing plate and orifice to regulate gas flow into the annular gap between the piston and cylinder.
