Abstract
(EN)
Provided are: a serrated metal gasket which has on both surfaces thereof, concentric serrated protrusions and recesses 1a, 1b, and in which the pitch of protrusions 3 constituting the serrated protrusions and recesses 1a, 1b is 1.2-1.8 mm, flat sections L each having a width of 50-180 μm are formed on the apex sections T of the protrusions 3, the depth of recesses 4 constituting the serrated protrusions and recesses 1a, 1b is 0.3-0.8 mm, and circular arcs each having a radius of 0.2-0.6 mm are formed on the lowermost section B of each recess 4; and a kammprofile gasket having the serrated metal gasket.
(FR)
L'invention concerne : un joint métallique dentelé qui a sur ses deux surfaces des saillies et des évidements dentelés concentriques (1a, 1b) et dans lequel le pas des saillies (3) constituant les saillies et les évidements dentelés (1a, 1b) va de 1,2 à 1,8 mm, des sections plates (L) ayant chacune une largeur de 50 à 180 µm sont formées sur les sections de sommet (T) des saillies (3), la profondeur des évidements (4) constituant les saillies et les évidements dentelés (1a, 1b) va de 0,3 à 0,8 mm, et des arcs circulaires ayant chacun un rayon de 0,2 à 0,6 mm sont formés sur la section la plus basse (B) de chaque évidement (4) ; et un joint de profil de came ayant le joint métallique dentelé.
(JA)
