Abstract
A joint for sealing around rods, shafts, cylinders and the like. A metallic sealing ring is configured for axial pressure control and is installed without substantial frictional contact with surfaces to be sealed. An actuating member is a part of the joint and is applied in a manner to expand inside and outside diameters of the sealing ring into contact with the sealed surfaces as a part of the installation process.
Claims7
A sealing joint, including means providing a recess and a rod projecting axially through said recess, said rod and an outer wall of said recess defining concentric radially spaced apart surfaces to be sealed, a continuous generally toroidal sealing member circular in cross section in said recess and providing sealing surfaces on inside and outside diameters thereof, an end face of the sealing member being open, an actuating member received in said recess and having a tapered nose portion to be received in the open end face of said sealing member, said members being in a preceding succeeding relation in said recess, and means for effecting an axial relative approaching motion of said members causing an interior penetration of said sealing member by the tapered nose portion of said actuating member and a relative separating motion of said sealing surfaces, said sealing member having a free height normally less than the distance between said surfaces to be sealed and being expansible by said means effecting an axial relative approaching motion of said members to move sealing surfaces thereon radially outwardly into contact with said surfaces to be sealed.
