Abstract
The invention relates to a flap seal in the form of a lamella seal, comprising at least three essentially flat individual rings (1, 10) lying one on top of another in a bundle-type form. Said individual rings (1, 10) comprise an inner part which is respectively defined by an inner circumferential surface (2, 11). The outer-lying individual rings (1) are covering rings, and the inner-lying individual rings (10) are sealing rings. High-quality sealing surfaces can be produced by allocating positioning means to the covering rings (1) for positioning said covering rings (1) in relation to one another in the circumferential direction and/or in relation to inner-lying sealing rings (10) in the radial direction. The positioning means also enable a relative movement in the axial direction.
