Abstract
Abstract A valve for a water faucet or the like of the type which when actuated does not have a part that rises, and which valve includes a rotary sealing plate against which spring loaded seals cooperate to seal the valve when the plate is turned to the ''''off'''' position. The valve includes a cartridge which has a stem formed as one piece along with the rotary valve and which cartridge also has a sleeve in which the stem rotates. The assembled sleeve is formed of two sleeves which are held in assembled relationship by means of a recess and projection connection, thereby the upper sleeve can be easily moved axially from the lower sleeve when the valve is to be disassembled. The lower sleeve has a pair of circumferentially spaced slots which function both as a water passage and also as a stop for limiting the rotation of the stem within the assembled sleeve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
177 words
A valve cartridge comprising, a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametrically opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a bridge portion of reduced cross sectional area intermediate its length, a pin extending through said bridge portion for abuttment with the ends of said slots in said lower sleeve when said stem is turned a maximum in one direction or another, said pin moving freely within said slots during said turning movement, and a valve plate having aperture means therethrough and carried by the lower end of said stem, water inlet means in the lower end of said lower sleeve and alignable with said aperture means in said valve plate when said stem is turned to a valve open direction.
Claim 2
Dependent Claim
177 words
A valve cartridge comprising, a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametrically opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a bridge portion of reduced cross sectional area intermediate its length, a pin extending through said bridge portion for abuttment with the ends of said slots in said lower sleeve when said stem is turned a maximum in one direction or another, said pin moving freely within said slots during said turning movement, and a valve plate having aperture means therethrough and carried by the lower end of said stem, water inlet means in the lower end of said lower sleeve and alignable with said aperture means in said valve plate when said stem is turned to a valve open direction.
Claim 3
Dependent Claim
46 words
A valve cartridge as set forth in claim 1 in combination with a valve body having recess means in the upper end thereof, said upper sleeve having lugs extending therefrom and adapted to seat in said recesses to prevent turning of said sleeve within said body.
Claim 4
Dependent Claim
41 words
The combination as set forth in claim 2 including an end cap threadably engaged in the upper end of said body and having an inwardly turned flange for abuttment against said upper sleeve to hold the latter captive in said body.
Claim 5
Dependent Claim
84 words
A sleeve assembly for a valve cartridge, said assembly comprising a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametrically opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, water inlet means in the lower end of said lower sleeve.
Claim 6
Dependent Claim
84 words
A sleeve assembly for a valve cartridge, said assembly comprising a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametrically opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, water inlet means in the lower end of said lower sleeve.
Claim 7
Dependent Claim
32 words
A sleeve assembly as set forth in claim 4 further characterzed in that said upper sleeve has lugs extending radially at one end thereof, and adapted to seat in a valve body.
Claim 8
Dependent Claim
27 words
The assembly set forth in claim 5 further characterized in that said upper sleeve has a radially inwardly turned flange for holding a valve stem captive therein.
Claim 9
Dependent Claim
278 words
A fluid valve assembly comprising; a cartridge having a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametricalLy opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a bridge portion of reduced cross sectional area intermediate its length, a pin extending through said bridge portion of abuttment with the ends of said slots in said lower sleeve when said stem is turned a maximum in one direction or another, said pin moving freely within said slots during said turning movement, and a valve plate having aperture means therethrough and carried by the lower end of said stem, water inlet means in the lower end of said lower sleeve and alignable with said aperture means in said valve plate when said stem is turned to a valve open direction; a valve body having recess means in the upper end thereof, said upper sleeve having lugs extending therefrom and adapted to seat in said recesses to prevent turning of said sleeve within said body, said upper sleeve also having a radially inwardly extending flange at the upper end thereof, said flange abutting against said stem to hold the latter captive in said upper sleeve, and an end cap threadably engaged on the upper end of said body and having an inwardly turned flange for abuttment against said upper sleeve to hold said cartridge captive in said body.
Claim 10
Dependent Claim
278 words
A fluid valve assembly comprising; a cartridge having a generally cylindrical lower sleeve having an internal fluid chamber, a pair of diametricalLy opposed and transversely arranged slots in said lower sleeve and communicating with said chamber, an upper sleeve disengagably connected with said lower sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves rotate as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a bridge portion of reduced cross sectional area intermediate its length, a pin extending through said bridge portion of abuttment with the ends of said slots in said lower sleeve when said stem is turned a maximum in one direction or another, said pin moving freely within said slots during said turning movement, and a valve plate having aperture means therethrough and carried by the lower end of said stem, water inlet means in the lower end of said lower sleeve and alignable with said aperture means in said valve plate when said stem is turned to a valve open direction; a valve body having recess means in the upper end thereof, said upper sleeve having lugs extending therefrom and adapted to seat in said recesses to prevent turning of said sleeve within said body, said upper sleeve also having a radially inwardly extending flange at the upper end thereof, said flange abutting against said stem to hold the latter captive in said upper sleeve, and an end cap threadably engaged on the upper end of said body and having an inwardly turned flange for abuttment against said upper sleeve to hold said cartridge captive in said body.
