Latest Patents

One of Jin Sakamoto's latest inventions includes an advanced Stirling engine design that features a unique configuration to enhance performance. This design incorporates an inner yoke of a linear motor installed on the outer peripheral surface of a cylinder. The innovative structure maintains a proper pressure balance between the compression space on one end and the back pressure space on the outer peripheral side of the cylinder. To achieve this, he established a first flow passage within the piston that connects the compression space to the outer surface and a second flow passage that communicates with the back pressure space. This second passage consists of a radial through hole penetrating the cylinder wall and a communication pathway between the cylinder's outer surface and the inner yoke's peripheral surface.

Another notable Stirling engine concept developed by Sakamoto features a pressure container that houses a working gas, with a cylinder secured within it. This design includes a power piston and a displacer that share the same axis, where the displacer is equipped with a sliding displacer piston and a hollow rod that traverses the center of the power piston.
