Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
178 words
A valve apparatus adapted for installation within a fluid conveying conduit comprising: an elongated body means having a pair of axially spaced opposed ends and a flow passage means which extends therebetween and includes an external peripheral portion of said body means located axially intermediate said opposed ends; a resiliently deformable ring means encompassing said body means with and inner peripheral portion thereof in peripheral sealing engagement with said external peripheral portion of said body means to close said fluid flow passage means; said resiliently deformable ring means having an outer peripheral portion which is adapted to engage the interior periphery of such a fluid conveying conduit in continuous circumferentially extending sealing engagement therewith; and said resiliently deformable ring means being operable upon compressive deformation thereof in a direction generally radially inward with respect to the longitudinal axis of said body means to open said fluid flow passage means radially intermediate said inner peripheral portion thereof and said external peripheral portion of said body means to permit fluid flow through said valve within said fluid flow passage means.
Claim 2
Dependent Claim
178 words
A valve apparatus adapted for installation within a fluid conveying conduit comprising: an elongated body means having a pair of axially spaced opposed ends and a flow passage means which extends therebetween and includes an external peripheral portion of said body means located axially intermediate said opposed ends; a resiliently deformable ring means encompassing said body means with and inner peripheral portion thereof in peripheral sealing engagement with said external peripheral portion of said body means to close said fluid flow passage means; said resiliently deformable ring means having an outer peripheral portion which is adapted to engage the interior periphery of such a fluid conveying conduit in continuous circumferentially extending sealing engagement therewith; and said resiliently deformable ring means being operable upon compressive deformation thereof in a direction generally radially inward with respect to the longitudinal axis of said body means to open said fluid flow passage means radially intermediate said inner peripheral portion thereof and said external peripheral portion of said body means to permit fluid flow through said valve within said fluid flow passage means.
Claim 3
Dependent Claim
18 words
The valve as set forth in claim 1 wherein said body means is a generally stepped cylindrical body.
Claim 4
Dependent Claim
25 words
The valve as set forth in claim 2 wherein said fluid flow passage means includes an elongated passage means extending longitudinally within said body means.
Claim 5
Dependent Claim
49 words
The valve as set forth in claim 3 wherein said body means includes a two piece body assembly comprised of an elongated inlet member having a bore means extending longitudinally from one end thereof and an elongated outlet member including an extension portion which is received within said bore.
Claim 6
Dependent Claim
17 words
The valve as set forth in claim 4 wherein said inlet member includes said elongated passage means.
Claim 7
Dependent Claim
25 words
The valve as set forth in claim 5 wherein said bore and said elongated passage means communicate with each other in fluid flow conveying relation.
Claim 8
Dependent Claim
30 words
The valve as set forth in claim 6 wherein said bore and said elongated passage means are formed by a generally stepped through bore extending axially within said inlet member.
Claim 9
Dependent Claim
40 words
The valve as set forth in claim 7 wherein said bore includes radially outward undercut portions extending longitudinally thereof which cooperate with said extension portion to define a part of said fluid flow passage means extending within said body means.
Claim 10
Dependent Claim
25 words
The valve as set forth in claim 8 wherein said external peripheral portion is located adjacent the external juncture between said inlet and outlet members.
Claim 11
Dependent Claim
49 words
The valve as set forth in claim 9 wherein said outlet member includes an enlarged diameter barrel portion adapted to engage the inner periphery of such a fluid conveying conduit and said barrel portion includes longitudinally extending groove means which form a portion of said fluid flow passage means.
Claim 12
Dependent Claim
57 words
The valve as set forth in claim 1 additionally including elongated resiliently deformable sleeve means encompassing said body means and maintained in continuous peripheral sealed engagement with said outer peripheral portion of said resiliently deformable ring means and with a portion of said body means located axially to one side only of said resiliently deformable ring means.
