摘要： The apparatus of the invention relates to a free piston Stirling engine that contains a power piston and a displacer piston which each reciprocate in a coaxial cylinder. At least one piston is hydrodynamically lubricated to avoid friction based wear by spinning the piston about its axis through the utilization of at least one magnetic article mounted onto one of the interfacing wall surfaces. The article magnetically interacts with a track made of magnetic material mounted on the opposing, interfacing surface so that during operation the interaction creates a torque which spins the piston about its axis and causes the desired lubrication to take place.

摘要： A regenerator accumulates cooling generated by expansion of refrigerant gas, and the regenerator includes a regenerator material which is made of a nonmagnetic material, a regenerator material which is made of a magnetic material, a container which includes a high temperature end and a low temperature end, and which accommodates the regenerator material made of the nonmagnetic material at the high temperature end side and the regenerator material made of the magnetic material at the low temperature end side. The container further accommodates an insertion member which narrows a passage area of the refrigerant gas flowing to a region accommodating the refrigerator material made of the magnetic material so that the passage area of the low temperature end side is narrower compared to the passage area of the high temperature end side.

摘要： In a vibration-reducing apparatus for a direct-acting type stirling engine, a change of pressure caused by the reciprocal movement of a displacer is applied to a power piston to produce a mechanical force, and the mechanical force is converted into an electric power by a direct-acting type electric generator which is directly connected to the power piston so as to effect reciprocating movements with the power piston. Such apparatus comprises a vibration-controlling actuator fixed to a cylinder to produce a vibration-controlling force in response to a drive-controlling signal given by the outside thereof, a detector for detecting an unbalanced movement by a force of inertia in the reciprocating movements of a direct-driving part consisting of the power piston and the direct-acting type electric generator, and a control circuit for receiving a detection signal from the detector to control the vibration-controlling actuator so that the vibration-controlling force of the vibration-controlling actuator cancels the unbalanced movement by the force of inertia caused by the reciprocating movements of the direct driving part.

摘要： A method and apparatus for snubbing the movement of a free, gas-driven displacer in a cooling engine are disclosed. The reciprocal movement of the free, gas-driven displacer is snubbed in each direction of movement as the displacer approaches top dead center and bottom dead center of its cycle by means of a magnetic snubber. Magnetic repulsion forces are generated between the displacer and the displacer containing cylinder of the cooling engine as the displacer approaches both top dead center and bottom dead center of its cycle. Each magnetic repulsive force is non-linear with respect to the displacer and the corresponding end of the displacer containing cylinder.
