Abstract
The valve is provided with two sharp edge discs, separated by a conical sealing surface, which forms two annular, viscosity-insensitive orifices in series, in respect to converging surfaces of revolution of the fuse valve bore. The high controlled acceleration of the conical sealing surface past its trigger point, obtained through the converging surfaces, results in extremely short closing time, with min. volume of liq. passed downstream of the fuse valve during the closing period. A controlled and high rate of deceleration of the conical sealing surface is provided just prior to seating of the surface. A conical sealing surface aligned guide is included, which allows liq. pressure to seat the conical surface on a circular edge with full circular contact.
