Abstract
Abstract A valve made up of a body and a sleeve telescopically received in the body. A hand wheel is concentrically received on the sleeve and threadably received on the body for moving the sleeve axially of the body. A seal is provided in the body between the body and the sleeve. The seal closes the flow passage between the body and the sleeve when the sleeve is moved to one extreme position and opens the flow passage when the sleeve is moved to another extreme position. The sleeve is non-circular so that it will not rotate relative to the body. The valve is suitable for use on hot water tanks and the like for closing off the flow of water.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
A valve comprising a body, a sleeve telescopically received in said body, said sleeve having a partition supported on one end, an external flange on said sleeve, a nut threadably received on said body and receiving said sleeve, a flange on said nut engaging said flange on said sleeve for moving said sleeve toward and away from said body, a sealing means in said body adapted to engage said partition on said sleeve whereby a flow passage through said valve is stopped when said sleeve is in a first position, said sleeve being movable to a second position whereby said partition is out of engagement with said sealing means whereby a flow passage is established through said valve, said sleeve having a oval shaped portion received in a complementary shaped portion in said body whereby said body and said sleeve are held against relative rotation.
Claim 2
Dependent Claim
145 words
A valve comprising a body, a sleeve telescopically received in said body, said sleeve having a partition supported on one end, an external flange on said sleeve, a nut threadably received on said body and receiving said sleeve, a flange on said nut engaging said flange on said sleeve for moving said sleeve toward and away from said body, a sealing means in said body adapted to engage said partition on said sleeve whereby a flow passage through said valve is stopped when said sleeve is in a first position, said sleeve being movable to a second position whereby said partition is out of engagement with said sealing means whereby a flow passage is established through said valve, said sleeve having a oval shaped portion received in a complementary shaped portion in said body whereby said body and said sleeve are held against relative rotation.
Claim 3
Dependent Claim
49 words
The valve recited in claim 1 wherein an external groove is provided on said sleeve, a snap ring in said groove, and said flange on said hand wheel is disposed between said flange on said sleeve and between said snap ring whereby said sleeve is moved by said handwheel.
Claim 4
Dependent Claim
50 words
The valve recited in claim 1 wherein said oval shaped portion has a peripheral groove therein, and an O-ring is supported on the external periphery of said sleeve, said O-ring engaging the inner periphery of said complementary portion of said body providing a seal between said sleeve and said body.
Claim 5
Dependent Claim
26 words
The valve recited in claim 1 wherein said sealing means comprises an O-ring disposed in an internal groove in said body slidably engaging said partition member.
Claim 6
Dependent Claim
115 words
A valve comprising a hollow body adapted to be connected to a source of liquid, said hollow body having an oval shaped portion therein, and a sleeve having an oval shaped portion slidably received in said body oval shaped portion whereby said sleeve is restrained against rotation, an internal groove in said body, an O-ring in said groove, said sleeve having a portion slidabLy engaging said O-ring when said sleeve is in a first position providing a seal against the flow of liquid, said sleeve being adapted to be moved to a second position at which position said O-ring is out of engagement with said sleeve whereby a flow path is provided through said valve.
Claim 7
Dependent Claim
115 words
A valve comprising a hollow body adapted to be connected to a source of liquid, said hollow body having an oval shaped portion therein, and a sleeve having an oval shaped portion slidably received in said body oval shaped portion whereby said sleeve is restrained against rotation, an internal groove in said body, an O-ring in said groove, said sleeve having a portion slidabLy engaging said O-ring when said sleeve is in a first position providing a seal against the flow of liquid, said sleeve being adapted to be moved to a second position at which position said O-ring is out of engagement with said sleeve whereby a flow path is provided through said valve.
Claim 8
Dependent Claim
39 words
The valve recited in claim 5 wherein said oval shaped portion of said sleeve has an external groove, a second O-ring in said external groove in said oval shaped portion, said second O-ring making sliding engagement with said body.
Claim 9
Dependent Claim
75 words
The valve recited in claim 5 wherein said sleeve has a closed end against said first O-ring and laterally disposed notches adjacent said closed end communicating with the inside of said sleeve, said first O-ring engaging said sleeve upstream of said notches when said sleeve is in a first position, said sleeve being adapted to move to a second position out of engagement with said first mentioned O-ring providing a flow passage through said sleeve.
