High-performance low-temperature Stirling engine with design-adapted to increased load requirements

摘要

The invention relates to a heat engine (M), in particular high-performance low-temperature Stirling engine with a pressure chamber formed by at least one housing part (1A, 2A, 1A-2A), which is pressure-tight with respect to the environment and filled with a working fluid (FL), and on a hot side (HS) by external heat input at higher temperature and on a cold side (KS) by external heat dissipation in relation to the higher temperature lower temperature mechanical output, wherein the at least one pressure chamber by periodically movable piston (3, 4) in It is provided that the working spaces are separated from each other by the pistons (3, 4) on the fluid side and in operative connection via the pistons (3, 4) on the pressure side, one of the pistons (3, 4 ) on the hot side (HS) by the external heat supply to the other on the cold side (KS) arranged piston (3 , 4) is brought to a higher temperature or maintained at a higher temperature, and the other on the cold side (KS) arranged piston (3, 4) opposite to the hot side (HS) arranged piston (3, 4) at a lower temperature held or brought to a lower temperature, wherein the pressure fluctuations generated in the work spaces periodically on the movable piston (3, 4) act, which are coaxially arranged with each other eccentric shafts (5, 6) in operative connection, wherein the coaxially arranged eccentric shafts (5 , 6) in the longitudinal direction of the eccentric shafts (5, 6) seen in a predetermined offset (V) are arranged eccentrically to one another.
