Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A valve comprising a valve body having a passageway extending therethrough, said passageway including a valve seat and a sealing section spaced therefrom, a valve member movably disposed in said passageway, a seating surface provided on said valve member for sealing engagement with said valve seat, means provided by said body and said valve member to maintain said valve member within said passageway and to permit movement of said valve member along said passageway so that said seating surface can be moved into and out of engagement with said valve seat, sealing-skirt means on said valve member which is in sealing engagement with said sealing section and remains in sealing engagement with said sealing section during movement of said seating surface into and out of engagement with said valve seat, said valve member including a bore therethrough, and bypass valve means seated in said valve member bore and movable to an unseated condition for permitting communication of said valve member bore and said valve body passageway.
Claim 2
Dependent Claim
166 words
A valve comprising a valve body having a passageway extending therethrough, said passageway including a valve seat and a sealing section spaced therefrom, a valve member movably disposed in said passageway, a seating surface provided on said valve member for sealing engagement with said valve seat, means provided by said body and said valve member to maintain said valve member within said passageway and to permit movement of said valve member along said passageway so that said seating surface can be moved into and out of engagement with said valve seat, sealing-skirt means on said valve member which is in sealing engagement with said sealing section and remains in sealing engagement with said sealing section during movement of said seating surface into and out of engagement with said valve seat, said valve member including a bore therethrough, and bypass valve means seated in said valve member bore and movable to an unseated condition for permitting communication of said valve member bore and said valve body passageway.
Claim 3
Dependent Claim
29 words
A valve according to claim 1 wherein said valve body has means for connection to a pressurized source of fluid supply which is in axial alignment with said member.
Claim 4
Dependent Claim
32 words
A valve according to claim 1 wherein said valve body has means for connection to a pressurized source of fluid supply which is generally offset to the disposition of said valve member.
Claim 5
Dependent Claim
38 words
A valve according to claim 1 wherein said means provided by said valve body and said valve member to maintain said valve member within said passageway comprises cooperating threaded section means along said passageway and said valve member,
Claim 6
Dependent Claim
51 words
The structure as recited in claim 1, and further including: a nipple connected to said valve body and provided with a nipple passageway therethrough communicating with said valve body passageway, said seating surface in seating engagement with said valve seat interrupting communication between said nipple passageway and said valve body passageway.
Claim 7
Dependent Claim
77 words
A valve according to claim 1 wherein said bypass valve means includes another valve seat within said bore, sealing means in removable sealing engagement with said another valve seat, spring means maintaining said sealing means in sealing engagement with said another valve seat, and retaining means retaining said spring means under spring compression so that said spring means maintains said sealing means in sealing engagement with said another valve seat under the action of said spring comPressing.
Claim 8
Dependent Claim
28 words
A valve according to claim 6 and further including guide means within said bore for guiding said sealing means into removable sealing engagement with said another valve seat.
Claim 9
Dependent Claim
146 words
In a valve, a member having a bore extending therethrough, a valve seat provided by said bore, projections extending outwardly from said bore at spaced locations therearound, said projections extending axially along said bore from said valve seat to a position spaced from said valve seat, said bore between said projections defining arcuate sections having a total area at the downstream side of said valve seat slightly less than the area of the entrance to the valve seat, sealing member means disposed against said valve seat, spring means engaging said sealing member means, retaining means secured in said bore and retaining said spring means in compression so that said spring means maintains said sealing member means against said valve seat under a predetermined spring pressure, and teeth means on said retaining means for biting into said valve member thereby anchoring said retaining means in said bore.
Claim 10
Dependent Claim
146 words
In a valve, a member having a bore extending therethrough, a valve seat provided by said bore, projections extending outwardly from said bore at spaced locations therearound, said projections extending axially along said bore from said valve seat to a position spaced from said valve seat, said bore between said projections defining arcuate sections having a total area at the downstream side of said valve seat slightly less than the area of the entrance to the valve seat, sealing member means disposed against said valve seat, spring means engaging said sealing member means, retaining means secured in said bore and retaining said spring means in compression so that said spring means maintains said sealing member means against said valve seat under a predetermined spring pressure, and teeth means on said retaining means for biting into said valve member thereby anchoring said retaining means in said bore.
Claim 11
Dependent Claim
22 words
In a valve according to claim 8 wherein said projections define guide means for guiding said sealing member means along said bore.
Claim 12
Dependent Claim
39 words
In a valve according to claim 8 wherein said retaining means includes a tubular section, said spring means is a coil spring, said tubular section being disposed within the end of said coil spring positioned against said retaining means.
