Abstract
Miniaturised device, which can operate as an engine or a cooler according to a Stirling thermodynamic cycle, comprising an expansion chamber and a compression chamber, which are interconnected by means of a regenerator enabling the working fluid to flow through from the expansion chamber to the compression chamber, and vice versa, under the effect of the movement of a displacing mechanism, a fraction of the compression chamber being mobile and operating as a piston in order to modify the volume of the said compression chamber, characterized in that it also comprises a complementary chamber which is connected to the compression chamber by means of a complementary connection channel, the said complementary chamber being at an intermediate temperature between the temperature of the compression chamber and the temperature of the expansion chamber, the complementary chamber being separated from the expansion chamber by means of the displacing mechanism.
