摘要： The object of the invention is to optimize the energy balances for a Stirling engine comprising a heated cylinder head having a plurality of approximately U-shaped heater pipes and a cooler. In particular the invention should provide a solution by means of which the transmission of heat to the heater pipes and the performance of the cooler are improved. To that end, the outwardly directed partial pipes (4c) of the heater pipes (4) through which the working medium flows are provided at least in given regions with a ceramic backing (11) for optimizing the flow (10) of hot gases. The cooler takes the form of a light metal body (20) around which coolant flows, which has radial ribs (23) and is disposed in a pot-like housing (21), the spacing between the radial ribs (23) being larger than the gap (25) between the inner wall of the pot and the outer radial rib delimiting wall.

摘要： The invention relates to a Stirling engine (1) with a heatable cylinder head (2) and a radiator (7) for heating or cooling a working medium and with a displacer piston (6) and a working piston (8) which operatively act upon an output shaft (22). The object of the invention is to provide sufficient counterbalance and to prevent redundant bearings and to achieve reduction in transverse forces. The object is attained in that the output shaft (22) is provided with a double eccentric disc (16) on which the working-piston connecting rod (14) and the displacer-piston connecting rod (14) engage, both eccentricities being in the plane of the piston axis.
