Abstract
Abstract A improved high pressure seal for sealing between a pair of vacuum system elements (10, 12) is disclosed which includes a channel (42) to allow fluid to be vented from the space between a sealing member (30) and a seal on the low pressure side of one of the elements (10, 12) to prevent the trapping of gasses inside of the seal which can contribute to outgassing at a later time. The venting channel (42) is formed either in the deformable sealing member (30) itself, or in one of the two vacuum system elements (10, 12) in its face adjoining the sealing member (30).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a central ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and one of the group composed of the sealing member and the two elements having at least one channel formed therein to allow any fluid confined by the ridge in the sealing member between the sealing member and a one of the elements to be drawn into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 2
Dependent Claim
176 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a central ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and one of the group composed of the sealing member and the two elements having at least one channel formed therein to allow any fluid confined by the ridge in the sealing member between the sealing member and a one of the elements to be drawn into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 3
Dependent Claim
37 words
A high pressure seal as claimed in claim 1 wherein the channel is formed in the sealing member, the channel extending radially along the surface of the sealing member at least as far as the ridge therein.
Claim 4
Dependent Claim
26 words
A high pressure seal as claimed in claim 2 wherein the channel is formed on the same side of the sealing member as the ridge therein.
Claim 5
Dependent Claim
25 words
A high pressure seal as claimed in claim 2 wherein the channel is formed on the opposite side of the member from the ridge therein.
Claim 6
Dependent Claim
22 words
A high pressure seal as claimed in claim 1 wherein the channel is formed in the face of one of the elements.
Claim 7
Dependent Claim
167 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a center ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and the sealing member having at least one radially extending channel cut through the ridge formed in it to allow fluid, confined behind the ridge between the sealing member and one of the elements, to be drawn into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 8
Dependent Claim
167 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a center ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and the sealing member having at least one radially extending channel cut through the ridge formed in it to allow fluid, confined behind the ridge between the sealing member and one of the elements, to be drawn into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 9
Dependent Claim
169 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a central ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and the sealing member having at least one radially extending channel formed therein on the side thereof opposite from the ridge, the channel allowing fluid confined between the sealing member and one of the elements to be drawn out into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 10
Dependent Claim
169 words
A high pressure seal for sealing between first and second vacuum system elements comprising: an annular deformable metallic sealing member which has a central ridge formed in it in its undeformed condition and which is held pressed between the elements in a flattened condition, the sealing member being deformed in its flattened condition to substantially conform to the shape of the cavity between the elements and to substantially fill the cavity, the sealing member having a pair of faces and inner and outer sealing edges, a sealing shoulder formed on each of the elements arranged so as to abut and seal against a respective one of the sealing edges on the sealing member, and the sealing member having at least one radially extending channel formed therein on the side thereof opposite from the ridge, the channel allowing fluid confined between the sealing member and one of the elements to be drawn out into the interior of the elements to avoid the possibility of later outgassing from the confined fluid.
Claim 11
