FLUID COUPLING AND METHOD OF DESIGNING THE SAME

摘要

A projection (7) of a gasket (4) has a trapezoidal shape defined by an inwardly facing inclined face (7a) as an outer periphery, an outwardly facing inclined face (7b) as an inner periphery, and a flat face (7c) as a tip face. The hardness of the gasket (4), the angle formed by the inclined faces (7a, 7b) of the projection (7), the height of the projection, and the area of the flat face (7c) of the projection tip are set so that a thrust value during tightening is between predetermined minimum and maximum values.
