Abstract
Abstract A single lever faucet valve cartridge for use within a faucet valve having hot and cold water inlets and for variably controlling the flow of water through these inlets. The valve cartridge includes a valve disc which is received in fluid tight sliding engagement over the inlets and which includes a pair of bores which can be aligned with the inlets by sliding movement of the disc to permit controlled flow of water from the inlets. The cartridge also includes a generally cylindrical cartridge body and a sealing member which are secured together in a snap fit relationship and which define a cylindrical chamber for rotatably supporting a cylindrical barrel. A lever is pivotably mounted intermediate its ends in a slot in the barrel so that it is journaled between the body member and the sealing member such that it has universal joint movement. One end of the lever protrudes from the sealing member for attachment to a faucet handle and the other end of the lever protrudes through a flat bottom wall of the cartridge body and is received in a bore in the valve disc in a snap fit relation. Movement of the lever will thus cause a sliding movement of the valve disc for alignment of the bores with the hot and cold water inlets.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
228 words
A single lever faucet valve cartridge for use with a faucet valve having a chamber for receiving the faucet valve cartridge and including fluid pressure inlets, said faucet valve cartridge comprising: a valve disc received in slideable fluid tight relationship over said inlets for variably blocking said inlets and including spaced bores for alignment with said inlets to permit fluid flow therethrough, a generally cylindrical cartridge body having a transverse generally flat wall for receiving said valve disc thereagainst in sliding relation, a sealing member engageable with an end of said body opposite said flat wall, said cartridge body and said sealing member defining a cylindrical chamber therebetween, a generally cylindrical barrel including a slot therethrough, and rotatably receivable in said cylindrical chamber such that the axis of said cylindrical barrel is parallel to said flat wall, and a lever pivotably received in and extending through said slot and journaled therein for universal joint movement with respect to said body and sealing member, said sealing member further including a bore extending therethrough, through which one end of said lever extends, and said lever being operably connected to said valve disc whereby movement of said one end of said lever causes sliding movement of said valve disc parallel to said flat wall and with respect to said inlets to permit variable alignment of said spaced bores with said inlets.
Claim 2
Dependent Claim
228 words
A single lever faucet valve cartridge for use with a faucet valve having a chamber for receiving the faucet valve cartridge and including fluid pressure inlets, said faucet valve cartridge comprising: a valve disc received in slideable fluid tight relationship over said inlets for variably blocking said inlets and including spaced bores for alignment with said inlets to permit fluid flow therethrough, a generally cylindrical cartridge body having a transverse generally flat wall for receiving said valve disc thereagainst in sliding relation, a sealing member engageable with an end of said body opposite said flat wall, said cartridge body and said sealing member defining a cylindrical chamber therebetween, a generally cylindrical barrel including a slot therethrough, and rotatably receivable in said cylindrical chamber such that the axis of said cylindrical barrel is parallel to said flat wall, and a lever pivotably received in and extending through said slot and journaled therein for universal joint movement with respect to said body and sealing member, said sealing member further including a bore extending therethrough, through which one end of said lever extends, and said lever being operably connected to said valve disc whereby movement of said one end of said lever causes sliding movement of said valve disc parallel to said flat wall and with respect to said inlets to permit variable alignment of said spaced bores with said inlets.
Claim 3
Dependent Claim
32 words
The faucet valve cartridge set forth in claim 1 wherein said cylindrical barrel includes depressions therein for receiving lubricating substance, and wherein said depressions and said cylindrical chamber form fluid tight chambers.
Claim 4
Dependent Claim
30 words
The faucet valve cartridge set forth in claim 1 wherein said cartridge body and said sealing member are secured together in locked mating engagement by mating projection and slot means.
Claim 5
Dependent Claim
43 words
The faucet valve cartridge set forth in claim 1 wherein said lever includes a pair of cylindrical projections intermediate its length and extending transversely to its axis, and wherein said cylindrical barrel includes socket means for receiving said projections in pivotable seated relationship.
Claim 6
Dependent Claim
280 words
A single lever faucet valve cartridge for use with a faucet valve having a chamber for receiving the faucet valve cartridge, said chamber including a flat bottom wall with fluid pressure inlets therein, said faucet valve cartridge comprising: a valve disc received in slideable fluid tight relationship with said flat bottom wall over said inlets for variably blocking said inlets and including bore means for alignment with said inlets to permit fluid flow therethrough, a generally cylindrical cartridge body having a transverse generally flat wall for receiving said valve disc thereagainst in sliding relation and including a central bore therethrough, said bore having an axis perpendicular to said flat wall, a sealing member received by an end of said body opposite said flat wall and in locked mating engagement, said cartridge body and said sealing member defining a cylindrical chamber therebetween, a generally cylindrical barrel rotatably receivable in said cylindrical chamber such that the axis of said cylindrical barrel is parallel to said flat wall and including a central slot therethrough, said central slot extending transversely to the axis of said cylindrical barrel, and a lever received in and extending through said central slot, said lever being pivotably connected to said cylindrical barrel whereby said lever is journaled for universal joint movement with respect to said body, said sealing member further including a bore extending therethrough, through which one end of said lever extends, and said valve disc including a bore for receiving an opposite end of said lever whereby movement of said one end of said lever causes sliding movement of said valve disc against said flat wall to permit variable alignment of said spaced bores with said inlets.
Claim 7
Dependent Claim
280 words
A single lever faucet valve cartridge for use with a faucet valve having a chamber for receiving the faucet valve cartridge, said chamber including a flat bottom wall with fluid pressure inlets therein, said faucet valve cartridge comprising: a valve disc received in slideable fluid tight relationship with said flat bottom wall over said inlets for variably blocking said inlets and including bore means for alignment with said inlets to permit fluid flow therethrough, a generally cylindrical cartridge body having a transverse generally flat wall for receiving said valve disc thereagainst in sliding relation and including a central bore therethrough, said bore having an axis perpendicular to said flat wall, a sealing member received by an end of said body opposite said flat wall and in locked mating engagement, said cartridge body and said sealing member defining a cylindrical chamber therebetween, a generally cylindrical barrel rotatably receivable in said cylindrical chamber such that the axis of said cylindrical barrel is parallel to said flat wall and including a central slot therethrough, said central slot extending transversely to the axis of said cylindrical barrel, and a lever received in and extending through said central slot, said lever being pivotably connected to said cylindrical barrel whereby said lever is journaled for universal joint movement with respect to said body, said sealing member further including a bore extending therethrough, through which one end of said lever extends, and said valve disc including a bore for receiving an opposite end of said lever whereby movement of said one end of said lever causes sliding movement of said valve disc against said flat wall to permit variable alignment of said spaced bores with said inlets.
