ABSTRACT:
A variable gland seal assembly wherein the seal about a cylindrical male inner member is accomplished in a manner that the opposed gland directional seal positioning conical bevelled components upon receiving the constant rate reacting force of a retained selected compression spring provide calculably controlled constant rate opposed conical known compressive symmetrical forces at opposed conical wedging areas upon a symmetrically opposed conical bevelled and opposed annular shouldered seal element producing opposed balanced annular seal wearing areas in a manner that effectively seals about the male inner member and upon other adjacent gland components while permitting said male member to have lineal, radial and torsional movements and substantially absorbing forces creating said male member's movements thus substantially eliminating said forces from reacting upon the gland seal assembly's supporting members and adjacent equipment and the like wherein said gland seal assembly has used the combination of said gland opposed directional seal positioning conical bevelled components calculably confined by said selected compression spring upon said seal element producing said opposed annular seal wearing surfaces at said seals opposed annular shoulders at said opposed conical wedging areas in a manner that said combination provides a wide range choice of seal materials and selected spring compressions to provide a readily variable gland seal adaptations such as for delicate compression of seal materials useful with frangible materials and piping systems, for firm compression of seal materials useful with metallic materials in high and low temperature and pressure piping systems as well as for driven shafting seals.
