Abstract
A packing ring for use between two surfaces to be sealed relative to each other is comprised of two ring components each of which is constituted by an assembly of ring segments which are provided with a projection at one end which engages a complementarily configured recess located at one end of an adjacent ring segment thereby providing a circumferentially extending interlocking of all segments of each ring. The ring segments of one ring are circumferentially staggered relative to the segments of the other ring by half a segment pitch, and each ring segment is provided with one or more recesses such that the respective recesses in the segments of the two rings are aligned in face-to-face relation so as to form a circumferential array of slots for receiving pressure springs.
Claims5
A packing ring structure for sealing two surfaces relative to each other comprising a pair of adjacently positioned ring components, each of said ring components being constituted by an assembly of ring segments provided with a projection at one end engaged with a complementarily configured recess at one end of an adjacent ring segment thereby providing a circumferentially extending interlocking of all the ring segments, said ring segments of the two ring components being staggered circumferentially relative to each other and each said ring segment being provided with at least one recess, the respective recesses in the segments of the two ring components being circumferentially aligned in face-to-face relation so as to form a circumferential array of slots, and pressure springs disposed in said slots.
