Abstract

Los enfriadores y motores tipo stirling, de pistón libre, se mejoran mediante un muelle que acopla el desplazador al pistón y que tiene un constante de muelle variable. La variación controlable de su constante de muelle permite la variación controlable de la carrera del desplazador, la salida de potencia del motor y la velocidad de bombeo térmico del enfriador, y por lo tanto la invención es útil para la limitación de la carrera y el acoplamiento de carga.
