DESCRIPTION OF T~E PREP~RE~ EM~03IME~T
As is describe~. in the a~ove-mentioned patents, the mixing valve of the present invention will customarily ~e positioned with-in a houslng which i~ a per~anent part of a plu~bing installation.
The movable valve ~ember, or ~t~m, will conventionally have a su~t-able operating mem~er, ei~her a lever or handle, for us~ in recip-rocating and ro~ating the valve m~ber to contxol the vol~me and temperature of water flowing through the valve. The valve finds application in kitchen faucets, lavatory faucets, shower installa~ions an~ the like. The valve cartridge is a replacea~le unit, thu~
permitti.ng a fauce~ or shower in~tallation to be quickly repaired ~y removing the faulty cartridge and replacing it with a new one.
A valve housing is indicated at 10 and is shown to be generally cylinariGal in orm with a closed bottom 12. The housing will have a pair of inlet ports, indicated at 14 and 16, and an outlet port 18. The outlet may go to an attachea spout or to a remote di~charge, such as a spray or ~hower head.
Position~d within the housing 10 is the valve cartridge ;-including a valve sleeve 20 and a valve member or stem 22, which .
is reciprocally and rotatably mounted within sleeve 20. The valve assembly made up of the ~leeve a~d valve me~ber is conventionally ., ~ . .. . . ... .
1()5'~Z~,9 mounted within the housing 10 by means of a spr~ ng clip 24, the legs of which are positioned in slot5 26 in the sleeve and pass through ope.nings 28 in housing 10.
The sleeve 20 is open at the bottom or inner end, as indicated at 30, and mounts a sleeve tube 3~ having a flange 34.
The sleeve tube 32 extends within sleeve 20, as indicated at 3~, and may preferably be formed of a plastic material providing rela-tively low friction to permit easy movement of stem 22 relative to the sleeve. The inner end o sleeve 20 has spaced axial notches 31 which receive projections 33 on sleeve tube 3~. A snap ring 35 fits within a groove 37 on the exterior of sleeve 20, passing through grooves 39 on projections 33 to thereby lock the sleeve tube to the sleeve.
Spaced outwardly from the inner end of the sleeve are inle. groups 38 and 40 which are in register with ~ousing inlets 14 and 16. The inner end of the sleeve may be sealed by an O-ring 42 positioned within a groove 44. A diagonal O-ring 46, positioned within a diagonal groove on the exterior of the sleeve is effective to prevent crossflow between hot and cold water ports 14 and 16.
Such a diagonal O-ring is shown in the above-mentioned U.S. patents.
An intermediate 0-ring 48 forms a seal ~etwe~n the exterior of the sleeve and $he interior of housing 10 outwardly of inlets 14 and 16. In like manner, the outer end of sleeve 22 carries an 0-r~ng seal 50. The sleeve may preferabi~ be formed of a suitable plastic material, although in some applications it may also be metallic.
Positioned within Yalve sleeve 20 i8 a flexible sleeve, for example a rubber sleeve, indicated at 52. A shoulder 54 fo~med on the interior of valve sleeve 20 positions one end of flexible sleeve 52 while the other end is conta~ned or positionea by end 56 of sleeve tube 3~. Thus, flexible sleeve 52 is positioned within valve sleeve 20 and at a location to mask sleeve inlet ports 38 and 40.
105;~ZZ9 The sleeve inlets are zssociated wi~h sleeve exte~ior recesses 3~a and ~Oa, directly in co~munication with housing po~ts 14 and 16. Water moving into sleeve inlet ports 38 and 40 will be directed toward the flex~bl~ sleeve and will effect its partial collapse, which will permit the water to flow toward sleeve outlets 5~. There may be two, three, four or more such outlets and they may be of varying size. The outlets open into an exterior chamber 62 formed between the interior of housing 10 and the exterior o~ sleeve 22, this chamber being in communication ~ith the housing outlet port 18.
The stem or valve member 22 has an exterior portion 64 which will accomodate either a lever or handle. The far interior portion of stem 22 mounts an O-ring ~ within a groove 68 to seal the inner end of the stem to sleeve tube 32. An axially-extending passage 70 connects the inner end of the stem with a~mosphere through a side passage 72 so that the ~tem is pressure-balanced, by atmos-pheric pressure, in both its open and closed positions.
Directly above that portion of the stem carrying o-ring 66 is a cam member 76, shown particularly in Figure 4. Cam member 76 has an exterior ~omewhat cylindrical surface 78, whose outer - diameter is general.'y the same as the inner diameter of flexible sleeve S2. Cam member 76 extends an axial distan~e greater than that of flexible sleeve 52 ~o that it can be in contact with the interior ~urface of the flexible sleeve in all po~itions of the stem.
Cam section 76 defines an open area or recess 80 which wlll permit the inward ~lexing or collapsing of sleeve 52, as shown part~cularly in Figure 3, ~o that water from the inlet can be pa~sed bet~een the inner surface of valve sleeve 20 and flexible slee~e 52 to sleeve outlets 58. Thus, the position of cam 7~ relative to the inlet ports determines the volume and desree of mixing of water flowing from the inlet ports to the outlets.
~OS;~Z'29 ~ osition~d outwardly of cam section 76 on stem 22 is a cylindrical portion ~2 having gener211y the s~.e outer di~.1eter as the inner diametex of the valve sleeve and positioned to mask the valve sleeve outlets ~hen in the closed position of Figure
: The present invention relates to valves of the type generally shown in my prior Patents 3,103,231 and 3,20~,656. The present inYentiOn particularly relates to a mixing valve of this t~pe using a ~lexible sleeve to control ~hP volume and temp~rature of water passing through the valve.
One purpose of the invention is a mixing valve, insertable as a cartridge within a valve housing, and including a ftexible sleeve positioned between a movable val~e member and a stationary sleeve.
Ano~her purpose is a valve member of the type described in which the ~lexible sleeve controlling passage of water from the Yalve inlets when the valve is in the open position, also provides a seal when the valve is in the closed position.

DESCRIPTION OF T~E PREP~RE~ EM~03IME~T
As is describe~. in the a~ove-mentioned patents, the mixing valve of the present invention will customarily ~e positioned with-in a houslng which i~ a per~anent part of a plu~bing installation.
The movable valve ~ember, or ~t~m, will conventionally have a su~t-able operating mem~er, ei~her a lever or handle, for us~ in recip-rocating and ro~ating the valve m~ber to contxol the vol~me and temperature of water flowing through the valve. The valve finds application in kitchen faucets, lavatory faucets, shower installa~ions an~ the like. The valve cartridge is a replacea~le unit, thu~
permitti.ng a fauce~ or shower in~tallation to be quickly repaired ~y removing the faulty cartridge and replacing it with a new one.
A valve housing is indicated at 10 and is shown to be generally cylinariGal in orm with a closed bottom 12. The housing will have a pair of inlet ports, indicated at 14 and 16, and an outlet port 18. The outlet may go to an attachea spout or to a remote di~charge, such as a spray or ~hower head.
Position~d within the housing 10 is the valve cartridge ;-including a valve sleeve 20 and a valve member or stem 22, which .
is reciprocally and rotatably mounted within sleeve 20. The valve assembly made up of the ~leeve a~d valve me~ber is conventionally ., ~ . .. . . ... .
1()5'~Z~,9 mounted within the housing 10 by means of a spr~ ng clip 24, the legs of which are positioned in slot5 26 in the sleeve and pass through ope.nings 28 in housing 10.
The sleeve 20 is open at the bottom or inner end, as indicated at 30, and mounts a sleeve tube 3~ having a flange 34.
The sleeve tube 32 extends within sleeve 20, as indicated at 3~, and may preferably be formed of a plastic material providing rela-tively low friction to permit easy movement of stem 22 relative to the sleeve. The inner end o sleeve 20 has spaced axial notches 31 which receive projections 33 on sleeve tube 3~. A snap ring 35 fits within a groove 37 on the exterior of sleeve 20, passing through grooves 39 on projections 33 to thereby lock the sleeve tube to the sleeve.
Spaced outwardly from the inner end of the sleeve are inle. groups 38 and 40 which are in register with ~ousing inlets 14 and 16. The inner end of the sleeve may be sealed by an O-ring 42 positioned within a groove 44. A diagonal O-ring 46, positioned within a diagonal groove on the exterior of the sleeve is effective to prevent crossflow between hot and cold water ports 14 and 16.
Such a diagonal O-ring is shown in the above-mentioned U.S. patents.
An intermediate 0-ring 48 forms a seal ~etwe~n the exterior of the sleeve and $he interior of housing 10 outwardly of inlets 14 and 16. In like manner, the outer end of sleeve 22 carries an 0-r~ng seal 50. The sleeve may preferabi~ be formed of a suitable plastic material, although in some applications it may also be metallic.
Positioned within Yalve sleeve 20 i8 a flexible sleeve, for example a rubber sleeve, indicated at 52. A shoulder 54 fo~med on the interior of valve sleeve 20 positions one end of flexible sleeve 52 while the other end is conta~ned or positionea by end 56 of sleeve tube 3~. Thus, flexible sleeve 52 is positioned within valve sleeve 20 and at a location to mask sleeve inlet ports 38 and 40.
105;~ZZ9 The sleeve inlets are zssociated wi~h sleeve exte~ior recesses 3~a and ~Oa, directly in co~munication with housing po~ts 14 and 16. Water moving into sleeve inlet ports 38 and 40 will be directed toward the flex~bl~ sleeve and will effect its partial collapse, which will permit the water to flow toward sleeve outlets 5~. There may be two, three, four or more such outlets and they may be of varying size. The outlets open into an exterior chamber 62 formed between the interior of housing 10 and the exterior o~ sleeve 22, this chamber being in communication ~ith the housing outlet port 18.
The stem or valve member 22 has an exterior portion 64 which will accomodate either a lever or handle. The far interior portion of stem 22 mounts an O-ring ~ within a groove 68 to seal the inner end of the stem to sleeve tube 32. An axially-extending passage 70 connects the inner end of the stem with a~mosphere through a side passage 72 so that the ~tem is pressure-balanced, by atmos-pheric pressure, in both its open and closed positions.
Directly above that portion of the stem carrying o-ring 66 is a cam member 76, shown particularly in Figure 4. Cam member 76 has an exterior ~omewhat cylindrical surface 78, whose outer - diameter is general.'y the same as the inner diameter of flexible sleeve S2. Cam member 76 extends an axial distan~e greater than that of flexible sleeve 52 ~o that it can be in contact with the interior ~urface of the flexible sleeve in all po~itions of the stem.
Cam section 76 defines an open area or recess 80 which wlll permit the inward ~lexing or collapsing of sleeve 52, as shown part~cularly in Figure 3, ~o that water from the inlet can be pa~sed bet~een the inner surface of valve sleeve 20 and flexible slee~e 52 to sleeve outlets 58. Thus, the position of cam 7~ relative to the inlet ports determines the volume and desree of mixing of water flowing from the inlet ports to the outlets.
~OS;~Z'29 ~ osition~d outwardly of cam section 76 on stem 22 is a cylindrical portion ~2 having gener211y the s~.e outer di~.1eter as the inner diametex of the valve sleeve and positioned to mask the valve sleeve outlets ~hen in the closed position of Figure
2. No~e that in this position the lower edge ~4 o~ cylinc~rical portion 82 is in sealin~ relation with ~he edge of flexible sleeve 52. Thus, sleeve 52 not only permits water to pass ro~ the inlets, but orms a seal and closure with cylindrical stem portion 82 when the valve is ~n the closed posi~ion.
An O-r.ing 86 is positioned outwardly of cylindrical por-tion 82 and for~s a seal with the interior surface of sleeve 20.
In operation, rotation o~ the valve member or stem will ~ determine the degree of mixing of water from the hot ana cold watex ports and reciprocation will dete~mine the volume of water passing to ou~lets 58. The position of cam section 7~ relativ~
to the two inlet ports determines the degree to which water iS
permitted to flow, hy collapsing flexible sleeve 52, as particular-ly indicated in Figure 3. I~en the valve is in the full closea position of Figure 2, the inner sur~ace 84 of cylindrical por~ion 82 of the stem is in sealing relation with the edge of flexible sleeve - 52. ~hen the valve is in the full open position, a shoulder 88 formed on the interior surface o~ valve sleeve 2Q provide~ a stop foi the valve me~ber or stem.
O particular advantage is the ~act that the flexible sleeve 52 not only ~unctions to control the passage of water through the valve when it ~s open, but also provides a seal with the stem when the valve mem~er is in the closed position. The tube sleeve 32, preferably formed of plastic of a type having very low fxictional resistance, insures that the stem will be easily xotated and recip-~o rocated relative to the sleeve. Both the stem and the sleeve maybe formed o~ plastic ox they may be formed of metal.
An i~portant aspect of the invention is the fact that the flexible sleeve is water pressure e~ualized in both the open ~os~zz9 ancl close~ po~itions of the valve. In the open position, when the flexible sleeve colla~ses 50 that water may p~ss to the sleeve outlets~ water is present both outs~de of the 1exible sleeve and within it. In like mannert when the valve is closed, water flows within t}le flexinle sl~eve, due to the pressure upon the sleeve, from ~he sleeve inlets. IIowever, there is no possibility of lea~:age, as the actual closure seal fox the valve is formed by the cooperating surfaces on cylin~xical portion ~ anZ the flexible sleeve.
An additional advantase for the particular construction of ~lexible sleeve sho~m and described is that since it i5 cylindrical and therefore has identical ends, the sleeve ma~ be reversed in the event that one end becomes worn due to closure of the valve ~tem upon it. A reversal o~ the sleeve ef~ectively renews the entire valve structure.
Althou~h the utility o~ the ~alve structure has heretoore been described in connection with a mixins valve, it should be clear tha~ the principles disclosed are equally applicable to both a non-mixing type faucet and to a faucet structure which does no~ utilize ~he "cartridge" principle. Tooking particularly at Figure 8, a fauce~ of the kitchen type includes hot and cold water conduits 90 and 92 pas~ing within an escutcheon plate 94. Conduits 90 and 92 are connected to a hou~ing struc~ure 96 ha~ing a cavity 98.
~ounted upon the outer portion of housiIi~ structure 96 is a spout construction consistin~ of a cylinder 100 and an integral spout 102.
A port 104 in cylinder 100 connects spout 102 with aligned ports 106 in the upper ena of housing 9~ through a circumfexential passage 109 .
Positioned within the top of housing g6 is a sleeve me~b~r 110 having an outwardly-extending flange 112 which overlies the upper end of housin~ 96. Sleeve 11~ has a central bore 114 which is in alignment with cavity 98 and cooperates with the cavity ~o mount a reciprocal ancl xotatable valve stem 116. Sleeve 110 ha~ ports 10~ in alignment with passage 136. Valve stem 116 may be substan~ially ,, .. . ~, .. . . . . .. ..
105'~,2'~9 th~ ~me as valve stem 22 described in connection with the valve of Figures 1-7 and mounts a cap 113 and a levær 115.
A flexible sleeve 118 is seated upon an annular shoulder 120 formed in housing 9~, ~ith the upper end o sleeve llS cooperating wi~h the valve ste~ in the manner heretofore described to provide a closure seal and s'nutoff for the faucet.
The operation of the struc~ure of Fi~urP ~ is the same as that described in connection with the valve of Figures 1-7 The principal difference is that there i9 no inserta~le valve car-tridge o the type hereto~ore described. The flexible sleeve isdirectly positioned within the housing of the faucet.
Figure 9 shows the same principle applied to a lavatory faucet. In this case a housing body 122 mounts a cylindrical member 124, similar in interior configuration to housing 96 of Fi~ure 8. ~ousing 122 include~ an integral spout 126 connected by a con-dui~ 128 to a por~ 130 ~Jhich opens into the cavity defined by mem~er 124. Valve stem 132, which is the same as valve stem 116 in ~igure 8, is attached by means of a screw or the like 134 to a typical handle 136 which may be used to manipulate the stem so as to control the volume and temperature o~ water discharge through spout 126.
h' . A ~lex~ble sleeve 138 i~ mounted within member 124 and seated upon a shouldex 140. A sleeve me~er 135, simllar to member 110, is inserted within member 124. Again, the uppe~ end of flexible sle~ve 138 will coop^rate with the cylindrical portion of the val~e stem to fo~m the appropria~e seal and closure for the faucet. The operation o~ the structur~ of Figure 9 is the same as that of Figure 8 and of the valve disclosed in detail in Figures 1-7.
Whereas the preerred form of the invention has ~een shown and described herein, lt should be realized that there may be many modlfications, substitutions and al~era~ions ~hereto.
_~_ .. . ....
.
An O-r.ing 86 is positioned outwardly of cylindrical por-tion 82 and for~s a seal with the interior surface of sleeve 20.
In operation, rotation o~ the valve member or stem will ~ determine the degree of mixing of water from the hot ana cold watex ports and reciprocation will dete~mine the volume of water passing to ou~lets 58. The position of cam section 7~ relativ~
to the two inlet ports determines the degree to which water iS
permitted to flow, hy collapsing flexible sleeve 52, as particular-ly indicated in Figure 3. I~en the valve is in the full closea position of Figure 2, the inner sur~ace 84 of cylindrical por~ion 82 of the stem is in sealing relation with the edge of flexible sleeve - 52. ~hen the valve is in the full open position, a shoulder 88 formed on the interior surface o~ valve sleeve 2Q provide~ a stop foi the valve me~ber or stem.
O particular advantage is the ~act that the flexible sleeve 52 not only ~unctions to control the passage of water through the valve when it ~s open, but also provides a seal with the stem when the valve mem~er is in the closed position. The tube sleeve 32, preferably formed of plastic of a type having very low fxictional resistance, insures that the stem will be easily xotated and recip-~o rocated relative to the sleeve. Both the stem and the sleeve maybe formed o~ plastic ox they may be formed of metal.
An i~portant aspect of the invention is the fact that the flexible sleeve is water pressure e~ualized in both the open ~os~zz9 ancl close~ po~itions of the valve. In the open position, when the flexible sleeve colla~ses 50 that water may p~ss to the sleeve outlets~ water is present both outs~de of the 1exible sleeve and within it. In like mannert when the valve is closed, water flows within t}le flexinle sl~eve, due to the pressure upon the sleeve, from ~he sleeve inlets. IIowever, there is no possibility of lea~:age, as the actual closure seal fox the valve is formed by the cooperating surfaces on cylin~xical portion ~ anZ the flexible sleeve.
An additional advantase for the particular construction of ~lexible sleeve sho~m and described is that since it i5 cylindrical and therefore has identical ends, the sleeve ma~ be reversed in the event that one end becomes worn due to closure of the valve ~tem upon it. A reversal o~ the sleeve ef~ectively renews the entire valve structure.
Althou~h the utility o~ the ~alve structure has heretoore been described in connection with a mixins valve, it should be clear tha~ the principles disclosed are equally applicable to both a non-mixing type faucet and to a faucet structure which does no~ utilize ~he "cartridge" principle. Tooking particularly at Figure 8, a fauce~ of the kitchen type includes hot and cold water conduits 90 and 92 pas~ing within an escutcheon plate 94. Conduits 90 and 92 are connected to a hou~ing struc~ure 96 ha~ing a cavity 98.
~ounted upon the outer portion of housiIi~ structure 96 is a spout construction consistin~ of a cylinder 100 and an integral spout 102.
A port 104 in cylinder 100 connects spout 102 with aligned ports 106 in the upper ena of housing 9~ through a circumfexential passage 109 .
Positioned within the top of housing g6 is a sleeve me~b~r 110 having an outwardly-extending flange 112 which overlies the upper end of housin~ 96. Sleeve 11~ has a central bore 114 which is in alignment with cavity 98 and cooperates with the cavity ~o mount a reciprocal ancl xotatable valve stem 116.

A flexible sleeve 118 is seated upon an annular shoulder 120 formed in housing 9~, ~ith the upper end o sleeve llS cooperating wi~h the valve ste~ in the manner heretofore described to provide a closure seal and s'nutoff for the faucet.
The operation of the struc~ure of Fi~urP ~ is the same as that described in connection with the valve of Figures 1-7 The principal difference is that there i9 no inserta~le valve car-tridge o the type hereto~ore described. The flexible sleeve isdirectly positioned within the housing of the faucet.
Figure 9 shows the same principle applied to a lavatory faucet. In this case a housing body 122 mounts a cylindrical member 124, similar in interior configuration to housing 96 of Fi~ure 8. ~ousing 122 include~ an integral spout 126 connected by a con-dui~ 128 to a por~ 130 ~Jhich opens into the cavity defined by mem~er 124.

Again, the uppe~ end of flexible sle~ve 138 will coop^rate with the cylindrical portion of the val~e stem to fo~m the appropria~e seal and closure for the faucet. The operation o~ the structur~ of Figure 9 is the same as that of Figure 8 and of the valve disclosed in detail in Figures 1-7.
Whereas the preerred form of the invention has ~een shown and described herein, lt should be realized that there may be many modlfications, substitutions and al~era~ions ~hereto.
