Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
In or for a valve, an assembly including a valve seat with an opening therein and a pivot. ally mounted closure co-operable therewith, the closure having an annular ridge projecting towards the seat, and the seat having an annular resilient member mounted thereon such that on closing of the closure the ridge engages the resilient member to provide a seal, and in which a groove in the seat underlies part of the resilient member, said resilient member being deformable into said groove when the closure is closed.
Claim 2
Dependent Claim
87 words
In or for a valve, an assembly including a valve seat with an opening therein and a pivot. ally mounted closure co-operable therewith, the closure having an annular ridge projecting towards the seat, and the seat having an annular resilient member mounted thereon such that on closing of the closure the ridge engages the resilient member to provide a seal, and in which a groove in the seat underlies part of the resilient member, said resilient member being deformable into said groove when the closure is closed.
Claim 3
Dependent Claim
23 words
An assembly as claimed in Claim 1 wherein the resilient member is secured to the seat on one side only of the groove.
Claim 4
Dependent Claim
22 words
An assembly as claimed in Claim 2 wherein said side is the side closer to the flow opening through the valve seat.
Claim 5
Dependent Claim
42 words
An assembly as claimed in Claim 2 wherein said side is the side remote from the flow opening through the valve seat and means are provided to impede access of fluid medium to the space between the resilient member and the closure.
Claim 6
Dependent Claim
34 words
An assembly as claimed in any preceding claim wherein the groove contains resilient material to be contacted by the resilient member during deformation thereof and to urge the resilient member outwardly of the groove.
Claim 7
Dependent Claim
25 words
An assembly as claimed in Claim 1 wherein the resilient member is adapted to wrap around the ridge after initial sealing contact has been made.
Claim 8
Dependent Claim
27 words
An assembly as claimed in Claim 6 wherein the resilient member is adapted to contact the closure on either side of the ridge at high sealing pressures.
Claim 9
Dependent Claim
20 words
An assembly as claimed in any preceding claim in which the groove is vented through the seat body to atmosphere.
Claim 10
Dependent Claim
36 words
In or for a valve, an assembly including a valve seat and closure substantially as hereinbefore described with reference to Figures 5 to 7 or Figures 3 and 4 as modified by Figures 5 to 7.
Claim 11
Dependent Claim
36 words
In or for a valve, an assembly including a valve seat and closure substantially as hereinbefore described with reference to Figures 5 to 7 or Figures 3 and 4 as modified by Figures 5 to 7.
