Abstract
A multilayer cylinder head gasket has a pair of functional layers and a distance layer with aligned openings. Each functional layer has a full bead located radially outwardly from and extending about its opening. Each functional layer also has a half bead spaced from the full bead. The distance layer includes a first portion extending radially from the opening and having a first thickness. A second portion of the distance layer extends radially from the first portion and has a second thickness that is less than the first thickness. A third portion of the distance layer extends radially from the second portion and has a third thickness less than the second thickness. The distance layer comprises a plurality of pieces, and at least one of the pieces limits compression of at least one of the full beads when the functional layers are compressed together.
