METAL SEAL AND FLUID CONTROL APPARATUS

A metal seal can be crushed evenly without forming wrinkles and scratches due to sliding against first and second flat surfaces. The seal comprises a first/second end surface arranged to face the first/second flat surface, respectively. The first end surface comprises a first convex part having a cu...

Zusammenfassung:	A metal seal can be crushed evenly without forming wrinkles and scratches due to sliding against first and second flat surfaces. The seal comprises a first/second end surface arranged to face the first/second flat surface, respectively. The first end surface comprises a first convex part having a curved or flat surface that contacts the first flat surface, and a first projection that is formed shifted in a radial direction from the first convex part and has a ridge line that contacts the first flat surface. Prior to deformation, when the second end surface contacts the second flat surface and the first flat surface is separated from the first end surface, a point where a vertical distance between the first convex part and the second flat surface is the greatest and the ridge line are located on the same surface that is parallel to the first flat surface.
