Abstract
Abstract A sealing assembly for forming a tight sealing relationship between at least two elements which comprises a spline member having two lateral faces having at least one convex relief element on each face, a first element and a second element, each of which have at least one wall with a recess formed therein which is adapted to receive the relief element on each lateral face of the spline member, and wherein one of the elements defines a cavity adapted to receive the other element and the spline member whereby the spline member may be interposed between the walls of the elements to form a tight seal there between when the relief elements of the spline member are engaged with the recess in each of the walls to thereby prevent movement of one of the elements to the other.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
144 words
A sealing assembly for forming a tight sealing relationship between at least two separate elements which comprises a spline member having two lateral faces, each of said lateral faces having at least one convex relief element thereon, a first element and a second element, each of said first and second elements defining at least one wall, each of said walls having at least one recess formed therein adapted to receive said relief element and one of said elements defining a cavity adapted to receive the other of said elements and said spline member whereby said spline member forms a tight seal between said elements when said lateral faces of said spline member are interposed between said walls of said elements and said relief elements are engaged with said recesses in said wall to thereby prevent movement of said elements with respect to each other.
Claim 2
Dependent Claim
144 words
A sealing assembly for forming a tight sealing relationship between at least two separate elements which comprises a spline member having two lateral faces, each of said lateral faces having at least one convex relief element thereon, a first element and a second element, each of said first and second elements defining at least one wall, each of said walls having at least one recess formed therein adapted to receive said relief element and one of said elements defining a cavity adapted to receive the other of said elements and said spline member whereby said spline member forms a tight seal between said elements when said lateral faces of said spline member are interposed between said walls of said elements and said relief elements are engaged with said recesses in said wall to thereby prevent movement of said elements with respect to each other.
Claim 3
Dependent Claim
18 words

Claim 6
Dependent Claim
16 words
An assembly as defined in claim 1 wherein at least one of said elements is deformable.
Claim 7
Dependent Claim
23 words
An assembly as defined in claim 1 wherein said relief element on each of said lateral faces of said spline member are symmetrical.
Claim 8
Dependent Claim
18 words
An assembly as defined in claim 1 wherein said relief elements comprise a boss on said spline member.
Claim 9
Dependent Claim
17 words
An assembly as defined in claim 1 wherein said relief elements have a substantially semicircular cross section.
Claim 10
Dependent Claim
16 words
As assembly as defined in claim 1 wherein said relief elements have a triangular cross section.
Claim 11
Dependent Claim
23 words
An assembly as defined in claim 1 wherein said spline member has a plurality of relief elements on each of said lateral faces.
Claim 12
Dependent Claim
23 words
An assembly as defined in claim 10 wherein said lateral faces of said spline member are serrated form said plurality of relief elements.
Claim 13
Dependent Claim
35 words
An assembly as defined in claim 10 wherein the plurality of relief elements are staggered on one of said lateral faces relative to the plurality of relief elements on the other of said lateral faces.
Claim 14
Dependent Claim
21 words
An assembly as defined in claim 1 wherein the plurality of relief elements are provided in a continuous or discontinuous manner.
Claim 15
Dependent Claim
31 words
An assembly as defined in claim 1 wherein said spline member has a thickness in the range of 5 to 35 percent of the wall thickness of one of said elements.
Claim 16
Dependent Claim
30 words
An assembly as defined in claim 1 wherein said spline member has a thickness in the range of 12 to 20 percent of the thickness of one of said elements.
Claim 17
Dependent Claim
62 words
An assembly as defined in claim 1 wherein said first element is a substantially cylindrical cover defining a substantially cylindrical outer wall, said outer wall defining said recess and said second element is a substantially hollow cylindrical element having an inner wall corresponding to said outer wall, said inner wall defining said recess and defining a cavity adapted to receive said cover.
Claim 18
Dependent Claim
43 words
An assembly as defined in claim 16 which includes means for fixing said spline member to said outer wall of saId cover whereby said spline member is folded along said outer wall of said cover where said cover is inserted in said cavity.
Claim 19
Dependent Claim
