FIELD: engines and pumps.
SUBSTANCE: invention relates to external heat supply engines. This engine comprises working piston and displacer pistons in different cylinders. Output shaft incorporates the crank articulated via con-rod with working piston. Oscillating sleeve with shaft fitted therein are pivoted inside said housing on one axle. Both sleeve and shaft are equipped with cranks articulated via con-rods with displacer pistons. In-cylinder spaces above displacer pistons are hot chambers. In-cylinder spaces under displacer pistons are cold chambers. Working medium is fed from hot chambers into cold chambers via heaters, regenerators and coolers. Cold chambers are communicated via working medium lines with appropriate above-piston and under-piston chambers of the cylinder with working piston. Engine runs with phase shift between working piston and displacer piston.
EFFECT: working cycle approximates to ideal Stirling cycle.
