Abstract
A regenerative heat-exchanger of a gas turbine whose ceramic heat-exchanger disk is coaxially surrounded by a metallic toothed rim under formation of an annular space in which are arranged springs; the springs are constituted by spring packets of cup springs which are guided on both sides in concave recesses in two webs arranged in the circumferential direction on entrainment plates which surround the lateral surfaces of the toothed rim and are non-rotatably connected therewith.
Claims7
A regenerative heat-exchanger of a gas turbine, comprising a ceramic heat-exchanger disk, a metallic toothed rim substantially coaxially surrounding the heat-exchanger disk while forming an annular space, spring means arranged within the annular space which are supported under prestress, on the one hand, at entrainment plate means abutting at the circumference of the heat-exchanger disk and, on the other, against the inside of the toothed rim, characterized in that the spring means are formed by spring packets of cup springs which are guided on both sides in concave recess means provided in two webs arranged in the circumferential direction on the entrainment plate means, said webs surrounding the lateral surfaces of the toothed rim and being non-rotatably connected therewith.
