ELASTICALLY RESPONSIVE UNIBODY SHEAR VALVE

摘要

A shear valve utilizing an elastically responsive unibody seal member in operation. The unibody seal member is of unitary constriction and in terms of adjacent ends thereof and an energizing member disposed therebetween. Thus, governing of fluid flow through the metal valve may be achieved without undue concern over high pressure differentials, for example in a downhole environment. Further, the unitary construction of the seal member alleviates concern over mismatching tolerances and/or dimensions for separately assembled miniaturized components of the valve.
