ultraweiche poetry with doppelummantelung

摘要

The seal, designed for use between two media at different temperatures and pressures, bounded by two walls with a space between, consists of a supple strip (2) with its width greater than the space between the two walls, and a rigid outer shell (5I, 5E) which holds the centre of the strip and leaves its edges (7I, 7E) free. The supply strip is in two sections - an outer one (2E) and an inner one (2I), each with a convex central portion (6E, 6I) round an inner flexible metal core (3), e.g. in the form of a spring. The outer shell is also made from outer (5E) and inner (5I) sections with convex central portions (9E, 9I), and the core is surrounded by a rigid ring (4).
