Abstract
An improved crank-type Stirling engine. A spring, preferably a gas spring, is linked between the displacer and the housing or alternatively the power piston. The spring is relaxed at substantially a mean position of the displacer to apply a centering force upon the displacer. The spring reduces the loading on the displacer drive linkage by itself exerting a centering force upon the displacer. If desired, displacer linkage forces may be reduced nearly to zero by designing the spring so that the spring constant and the masses upon which it operates are in resonance. The gas spring mechanism may include pump elements so that it will operate as a pump to charge the engine to operating pressure with atmospheric air during initial start up operation.
