Abstract
A thermodynamic machine () of a Stirling type, the machine comprising an expansion chamber (), a compression chamber (), a regenerator () disposed between the expansion and compression chambers; a first heat exchanger () in communication with the expansion chamber and the regenerator; a second heat exchanger () in communication with the compression chamber and the regenerator; a first bypass conduit () connecting the expansion chamber with the regenerator bypassing the first heat exchanger; a second bypass conduit () connecting the compression chamber with the regenerator bypassing the second heat exchanger; at least a pair valves (), one valve () provided between the expansion chamber and the first heat exchanger and/or between the regenerator and the first heat exchanger and/or in the first bypass conduit between the expansion chamber and the regenerator; and the other valve () provided between the compression chamber and the second heat exchanger and/or between the regenerator and the second heat exchanger and/or in the second bypass conduit between the compression chamber and the regenerator; the valves being controllable.
