Abstract
Official abstract text for this publication.
An object is to provide a metal gasket that can form a wide contact width for a counterpart sealing face and that can achieve excellent sealing properties even when a blow hole is generated in the counterpart sealing face, and the object is achieved by a metal gasket having a bead portion to be in contact with a counterpart sealing face to form a sealing portion, formed on a gasket main body. The bead portion includes an arc portion that is convex toward the counterpart sealing face and hem-rising portions that each obliquely rise from the gasket main body toward the arc portion, on both hems of the arc portion. A connection portion between the arc portion and the hem-rising portion is formed to be convex toward a convex side of the bead portion. Plastic distortion for an overall width of the arc portion is lower than that of the connection portion. A contact pressure distribution in the arc portion in a compression state has a shape that is flat and wide in a width direction of the arc portion.
First claim
Opening claim text (preview).
1 . A metal gasket comprising a bead portion to be in contact with a counterpart sealing face to form a sealing portion, formed on a gasket main body, wherein the bead portion comprises an arc portion that is convex toward the counterpart sealing face, and hem-rising portions that obliquely rise from the gasket main body toward the arc portion, on both hems of the arc portion, wherein a connection portion between the arc portion and the hem-rising portion is formed to be convex toward a convex side of the bead portion, wherein plastic distortion of an overall width of the arc portion is lower than the plastic distortion of the connection portion, and wherein a contact pressure distribution in the arc portion in a compression state has a shape that is flat and wide in a width direction of the arc portion. 2 . The metal gasket according to claim 1 , wherein the bead portion is formed on each of both sides of the gasket main body, and is in contact with the counterpart sealing face arranged in each of the sides of the gasket main body to form the sealing portion. 3 . The metal gasket according to claim 1 , wherein an interval between the connection portions formed on both sides of the arc portion is the range of 0.4 mm to 10 mm. 4 . The metal gasket according to claim 1 wherein a curvature radius of the arc portion is the range of 2 mm to 20 mm. 5 . The metal gasket according to claim 1 , wherein a length per one side of the hem-rising portion is the range of one sixth to one third of an overall width of the bead portion. 6 . The metal gasket according to claim 1 , wherein the gasket main body is coated with an elastic substance.
