ABSTRACT:
The Stirling engine uses an annular cam for converting the reciprocating movements of the pistons of the engine in a rotating movement. The annular cam is concentric with the engine block and provides movement to a first piston located in a first radial cylinder. A second piston located in a second radial cylinder provides work to the annular cam. A working gas circuit located between the first and the second cylinders is provided for powering the engine. The circuit comprises a cooling assembly, a regenerator and a heating assembly. The pistons are operatively connected to the annular cam by means of a radial rod at the end of which are located rollers engaged with the inner cam path and maintained by an inner guide parallel to the cam path. The engine provides a very simple and economical construction of the Stirling engine.
