自由活塞 斯特灵 Engine (FPSE) eliminates the crankshaft and all mechanical linkages. The piston and displacer oscillate freely, their motion governed by the interplay of gas 压力 forces from the thermodynamic cycle and spring forces. This design enables hermetic sealing of the working gas, requires no lubrication, and offers extremely high reliability and long operational life, making it ideal for maintenance-free applications.
