The filler assembly includes at least one first filler and at least one second filler stacked in a longitudinal direction. A valve rod received in the axial hole extends through the at least one first filler and the at least one second filler. At least one of two mutually abutting faces respectively of the at least one first filler and the at least one second filler is at a non-parallel angle to a radial direction perpendicular to the longitudinal direction. If one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction, at least one of the at least one first filler and the at least one second filler is moved in the radial direction to press against the valve rod. ## Claims ### Claim 1 A filler assembly for a valve, with the valve including a body, a cap mounted to a top portion of the body and having an axial hole, and a valve rod extending through the axial hole of the cap, with the filler assembly adapted to be mounted in the axial hole of the cap, with the filler assembly adapted to seal a gap between the valve rod and an inner periphery of the axial hole, with the filler assembly comprising: at least one first filler including upper and lower faces spaced from each other in a longitudinal direction, with a first through-hole extending from the upper face through the lower face of the at least one first filler, with the valve rod adapted to extend through the first through-hole; and at least one second filler including top and bottom faces spaced from each other in the longitudinal direction, with a second through-hole extending from the top face through the bottom face of the at least one second filler, with the valve rod adapted to extend through the second through-hole, with the at least one second filler and the at least one first filler stacked upon each other and including two mutually facing and mutually abutting faces comprised of one of the upper and lower faces of the at least one first filler and one of the top and bottom faces of the at least one second filler, with at least one of the two mutually facing and mutually abutting faces being an arcuate or slant face at a non-parallel angle to a radial direction perpendicular to the longitudinal direction, wherein if one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction, at least one of the at least one first filler and the at least one second filler is moved in the radial direction to press against an outer periphery of the valve rod. ### Claim 2 (depends on 1) The filler assembly as claimed in claim 1, with the at least one first filler being annular and made of metal, with the at least one second filler being annular and made of graphite, with each of the at least one first filer and the at least one second filler adapted to press against the outer periphery of the valve rod when one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction. ### Claim 3 (depends on 1) The filler assembly as claimed in claim 1, with the at least one first filler including a plurality of first fillers, with the at least one second filler including a plurality of second fillers, with each of the plurality of second fillers located between two adjacent first fillers. ### Claim 4 (depends on 3) The filler assembly as claimed in claim 3, with each of the plurality of first fillers being annular and made of metal, with each of the plurality of second fillers being annular and made of graphite, with the upper face of each of the plurality of first fillers being flat, with the lower face of each of the plurality of the first fillers being a slant face at the non-parallel angle to the radial direction, with the top face of each of the plurality of second fillers being a slant face at the non-parallel angle to the radial direction and abutting the lower face of one of the plurality of the first fillers, with the bottom face of each of the plurality of second fillers being flat and abutting the upper face of one of the plurality of the first fillers. ### Claim 5 (depends on 3) The filler assembly as claimed in claim 3, with a groove defined in each of the top and bottom faces of each of the plurality of second fillers, with the groove in the top face of each of the plurality of second fillers having substantially V-shaped cross sections, with the groove in the bottom face of each of the plurality of second fillers having substantially inverted V-shaped cross sections, with at least one of the upper and lower faces of each of the plurality of first fillers being conic, with the groove of each of the top and bottom faces of each of the plurality of second fillers receiving one of the upper and lower faces of one of the plurality of first fillers. (FIG. 8) ### Claim 6 (depends on 5) The filler assembly as claimed in claim 5, with each of the top face of each of the plurality of first fillers including at least one screw hole or recess, with a tool adapted to be inserted into the at least one screw hole or recess for removing the plurality of first fillers out of the axial hole of the cap. ### Claim 7 (depends on 5) The filler assembly as claimed in claim 5, with the top face of each of the plurality of first fillers including an annular groove and at least one notch in communication with the annular groove, with a tool adapted to be inserted into the at least one notch for removing the plurality of first fillers out of the axial hole of the cap. ### Claim 8 (depends on 3) The filler assembly as claimed in claim 3, with one of the top and bottom faces of each of the plurality of second fillers having a positive slope, with another of the top and bottom faces of each of the plurality of second fillers having a negative slope, with each of the upper and lower faces of each of the plurality of first fillers having a slope corresponding to the positive slope or negative slope. ### Claim 9 (depends on 1) The filler assembly as claimed in claim 1, with each of the at least one first filler and the at least one second filler adapted to press against the inner periphery of the axial hole of the cap when one of the at least one first filler and the at least one second filler is subjected to the pressing force in the longitudinal direction, with each of the top face of each of the plurality of first fillers including at least one screw hole or recess, with a tool adapted to be inserted into the at least one screw hole or recess for removing the plurality of first fillers out of the axial hole of the cap. ### Claim 10 (depends on 1) The filler assembly as claimed in claim 1, with each of the at least one first filler and the at least one second filler adapted to press against the inner periphery of the axial hole of the cap when one of the at least one first filler and the at least one second filler is subjected to the pressing force in the longitudinal direction, with the top face of each of the plurality of first fillers including an annular groove and at least one notch in communication with the annular groove, with a tool adapted to be inserted into the at least one notch for removing the plurality of first fillers out of the axial hole of the cap. ### Claim 11 (depends on 1) The filler assembly as claimed in claim 1, with the at least one first filler including a first filler, with the at least one second filler including a plurality of second fillers stacked below the first filler, with the first filler being annular and made of metal, with each of the plurality of second fillers being annular and made of graphite, with two mutually abutting faces of two adjacent second fillers comprised of the top face of a lower one of the two adjacent second fillers and the bottom face of an upper one of the two adjacent second fillers, with at least one of the two mutually abutting faces of the two adjacent second fillers being an arcuate or slant face at the non-parallel angle to the radial direction. ### Claim 12 (depends on 11) The filler assembly as claimed in claim 11, with the lower face of the first filler being slant, with each of the top and bottom faces of each of the plurality of second fillers being slant, with the top face of a topmost one of the plurality of second fillers abutting the lower face of the first filler, with the bottom face of each of the plurality of second fillers abutting the bottom face of another of the plurality of second fillers.
