Abstract

A lenticular sealing ring comprises alternately arranged lamellae (1) made of expanded graphite and metal lamellae (2). The density of the graphite lamellae (1) increases from the inside toward the outside of the sealing ring. The layering is configured so that on both sides of the lenticular surfaces at least half of the curved surface is covered by a continuous graphite lamella (1') and a plurality of encircling metal and graphite lamellae (1, 2) terminated in the outer edge region.
