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 two piece sleeve in which the stem rotates. The assembled sleeve is formed of an upper sleeve and a lower sleeve 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 valve stem can be snapped into assembled relationship with the lower sleeve to facilitate assembly of the cartridge. Stop means are provided between the upper sleeve and the handle knob to limit rotation of the knob and its associated valve stem.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
198 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, circumferentially spaced stop means extending axially outwardly from said upper sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves act as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves, and having a hand knob removably secured thereto for rotating the stem, said knob having stop means engagable with said stop means on said sleeve to thereby limit rotational movement of said knob and stem, said stem having radially extending projection means of a slightly greater lateral width than the internal diameter of the said fluid chamber of the lower sleeve to form a snap-fit therewith, 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
198 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, circumferentially spaced stop means extending axially outwardly from said upper sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves act as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves, and having a hand knob removably secured thereto for rotating the stem, said knob having stop means engagable with said stop means on said sleeve to thereby limit rotational movement of said knob and stem, said stem having radially extending projection means of a slightly greater lateral width than the internal diameter of the said fluid chamber of the lower sleeve to form a snap-fit therewith, 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
51 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, said stop means on said sleeve extending through said cap.
Claim 5
Dependent Claim
309 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, circumferentially spaced stop means extending axially outwardly from said upper sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves act as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a hand knob removably secured thereto for rotating the stem, said knob having stop means engagable with said stop means on said sleeve to thereby limit rotational movement of said knob and stem, said stem having radially extending projection means of a slightly greater lateral width than the internal diameter of said fluid chamber of the lower sleeve to form a snap fit therewith, 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, said stop means on said sleeve extending through said cap.
Claim 6
Dependent Claim
309 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, circumferentially spaced stop means extending axially outwardly from said upper sleeve, a recess and projection connection between said upper and lower sleeves whereby said sleeves act as a unit and are disengagable by axial relative movement therebetween, a stem rotatably mounted within said sleeves and having a hand knob removably secured thereto for rotating the stem, said knob having stop means engagable with said stop means on said sleeve to thereby limit rotational movement of said knob and stem, said stem having radially extending projection means of a slightly greater lateral width than the internal diameter of said fluid chamber of the lower sleeve to form a snap fit therewith, 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, said stop means on said sleeve extending through said cap.
