Abstract
A hot and cold engine operating based on a regenerative gas cyclical process, with at least two pistons (2, 3), which separate at least three processing chambers (4, 6, 7) with an in-line arrangement of respectively at least one heat exchanger (13, 15) and at least one regenerator (11, 12) arranged in series with the heat exchanger. In order to eliminate the danger of freezing for the cold heat exchanger (15) and thus the air heat exchanger (16), at least one of the regenerators (12) assigned to the cold processing chamber (6) has a bypass (17) with a control valve (17a).
