Abstract: The invention relates to a thermoelastic energy converter (1), in particular for use in a thermoelastic heating/cooling apparatus or in a combined heat-and-power coupling system, comprising: an arrangement comprising multiple converter devices (3a, 3b), wherein each of the converter devices (3a, 3b) has one or more thermoelastic elements (4) arranged in a direction of extension; a loading device, in order to load the thermoelastic elements (4) of each of the multiple converter devices (3a, 3b) so as to have a temporally variable power curve; a coupling which is designed such that the loading device actuates the converter devices (3a, 3b) in a phase-offset manner with respect to their cyclic loading and unloading.
