Abstract
A heat-exchanger disk of a regenerative heat-exchanger of a gas turbine, which is secured on a rotatable carrier under interposition of ring-shaped, series-connected leaf spring elements which are connected with each other at their overlapping ends and which are supported with outwardly curved arcuate portions at counter-surfaces in a central opening of the heat-exchanger disk and with inwardly curved arcuate portions at counter-surfaces of the carrier; one retaining disk substantially coaxial to the heat-exchanger disk thereby abuts at each end face of the heat-exchanger disk whereby the two retaining disks hold the leaf spring elements in the carrier within the central opening and are connected with each other by tie-pins which extend through the annular space between the central opening and the carrier.
