Abstract
A linear-free piston Stirling machine comprising a displacer and a power piston. A rod is attached at one end to the displacer, extends through the power piston and is mounted to the casing at its opposite end via a spring. A resilient stopper at the opposite end is arranged to contact the engine casing if the displacement of the displacer exceeds a predetermined limit.
