ABSTRACT:
The power output of a free piston Stirling engine is regulated by a valve in the gas flow path from the cold space through the regenerator to the hot space. The valve causes restriction of the gas flow path as in response to piston excursion beyond a selected excursion amplitude. Increased excursion causes increased restriction. The result is that, for piston excursions beyond the selected amplitude, the power out diminishes for increased stroke making the engine stable with any load from zero to maximum and avoiding runaway.
