Definitions

  • This invention relates generally to sealing of faucets, when closed, and more particularly to replacement of seals in faucets, to achieve superior sealing performance.
  • faucet seals were typically flat-sided, annular in shape, for pressing of a flat side against an annular metallic seat; or washer, when the seal was displaced axially as during faucet closing.
  • Such annular, flat-sided seals depended upon substantial axial force exertion of a valve stem to develop seal deformation and sealing, and such force exertion increased the development of rubbing friction at interengaged rubber and metallic pressure transmitting surfaces, during relative rotation of such surfaces. Repeated faucet opening and closing often led to unwanted early wear and seal failure.
  • a long felt need has existed for a solution to such conventional faucet seal wear and required replacement.
  • a further object includes provision of a valve stem metallic lateral and annular surface engaging the seat, radially outwardly of the top level of an O-ring seal.
  • the valve stem typically defines a metallic skirt surrounding the metallic seat.
  • An added object includes provision of an elastomeric O-ring the radially outermost extent of which engages the flow bore, below the level of the metallic seat, which is engaged by the stem under-surface to define a metal-to-metal annular seal therewith. Two seals are thereby provided; a metal-to-metal annular seal and an elastomer-to-metal seal, within the bore.
  • an O-ring retention screw head typically defines a flat annular retention surface directly below the annular extent of the O-ring; and that flat annular surface has a periphery directly below about 2 ⁇ 3 of the bulk of the O-ring, whereby water pressurized deflection of the seal is upwardly and outwardly away from the screw head, and toward the metal-to-metal seal.
  • the invention also contemplates a method of repairing a faucet having a seat defining a bore, a valve stem, a flat annular seal to engage the seat above the bore, and a retention screw, the method including:
  • FIG. 1 is a section taken through an existing conventional faucet assembly
  • FIG. 1 a is an enlarged fragmentary section showing the method of sealing in the FIG. 1 faucet;
  • FIG. 2 is a section taken through a faucet embodying the invention, employing an O-ring seal
  • FIG. 2 a is an enlarged fragmentary section showing the method of sealing in the FIG. 2 faucet;
  • FIG. 3 shows the FIG. 2 faucet in open condition
  • FIG. 4 shows the O-ring assembled to a retention screw, as used in FIGS. 2 and 3 , and providing a kit in a container, to be sold as in hardware stores as a replacement seal and retainer, for use in a homeowner's faucet needing seal replacement.
  • an existing faucet 10 includes a body 11 defining upper and lower interior chambers 12 and 13 .
  • Inlet 14 delivers liquid such as water to chamber 13 , for controlled flow through a bore 15 in interior wall 16 .
  • An upwardly projecting annular valve seat 17 is formed at the upper end of the bore. When the valve is opened, liquid flows through the bore and past the seat to upper chamber 12 , and discharges at spout 19 .
  • a valve stem 30 is movable upwardly to open the valve, and downwardly to close the valve.
  • Handle 22 is rotatable to control upward and downward stem movement, and interengaged threads 23 and 24 carried on the stem and on the body offset stem movement, as the handle is rotated.
  • annular rubber washer 25 is carried by the stem 30 to downwardly engage the seat 17 , for sealing.
  • a screw 26 holds the washer in position, within a cavity 27 in a stem flange 28 .
  • Skirt 29 bounds the washer periphery.
  • the washer has flat, horizontal upper and lower sides 25 a and 25 b , and lower side 25 b deteriorates due to rotary rubbing or frictional pressure contact with narrow width seat 17 , which tends to “groove” the washer.
  • That seal is in the form of an annular O-ring 31 positioned so that it does not press downwardly on metallic seat 17 , and avoids rubbing rotary frictional contact with that narrow width seat, thereby avoiding the groove formation problem.
  • the valve stem and O-ring are typically characterized by one or more of the following:
  • the engagement of the stem surface 27 and seat 17 defines a metal-to-metal annular seal or stop, spaced upwardly and radially outwardly of the annular seal defined by engagement of the O-ring with the bore.
  • the screw head 26 defines a flat annular surface 32 directly below the major extent of the O-ring.
  • the screw head flat annular surface 32 has a periphery 32 a directly below and medially of the outer 1 ⁇ 2 of the bulk of the O-ring. In FIG. 2 a , the O-ring is not compressed, when the surface 27 engages seat 17 .
  • the method of repairing a faucet having a seat defining a bore, a valve stem, and an existing flat annular seal to annularly engage the seat above the bore, and a retention screw, with a replacement seal includes:
  • FIG. 4 shows a kit 60 that includes a container 61 , and replacement parts 26 and 31 within the container, for example to be sold to a homeowner, for faucet repair, including seal replacement.
  • O-ring 31 may be bond attached to the screw shank 26 a , or to screw head surface 32 .
