Abstract

Official abstract text for this publication.

A seal arrangement is provided having a first part with a seal gland, and a seal located in the seal gland. The seal has an outer sealing surface and an inner support surface that is supported on a bottom support surface of the seal gland. A second part having a sealing surface is provided against which the outer sealing surface of the seal is pressed. A relief area is formed in a portion of the bottom support surface of the seal gland, with the relief area being configured to receive a resiliently deflected portion of the inner support surface of the seal during assembly. A method of assembling a sealing arrangement is also provided.

First claim

Opening claim text (preview).

1 . A seal arrangement, comprising: a first part having a seal gland; a seal located in the seal gland, the seal having an outer sealing surface and an inner support surface that is supported on a bottom support surface of the seal gland; a second part having a sealing surface against which the outer sealing surface of the seal is pressed; and a relief area formed in a portion of the bottom support surface of the seal gland, the relief area being configured to receive a resiliently deflected portion of the inner support surface of the seal during assembly. 2 . The seal arrangement of claim 1 , wherein the relief area is formed in a medial area of bottom support surface of the seal gland. 3 . The seal arrangement of claim 1 , wherein the inner support surface of the seal extends on both sides of the relief area on the bottom support surface. 4 . The seal arrangement of claim 1 , wherein the relief area that is configured to receive the resiliently deflected portion of the inner support surface of the seal during assembly has a parabolic form in cross-section. 5 . The seal arrangement of claim 1 , wherein the second part includes a lead-in area configured to compress the seal during assembly of the first and second parts. 6 . The seal arrangement of claim 1 , wherein the relief area is formed as a machined cut in the bottom support surface. 7 . The seal arrangement of claim 1 , wherein the relief area has a volume that is less than about 15% of a volume of the seal. 8 . A method of forming a seal arrangement, the method comprising: providing a first part having a seal gland; forming a relief area in a portion of a bottom support surface of the seal gland; installing a seal in the seal gland, the seal having an outer sealing surface and an inner support surface that is supported on the bottom support surface of the seal gland; installing a second part having a sealing surface against the outer sealing surface of the seal by sliding the first and second parts together relative to one another; and compressing the seal during the installing step such that a resiliently deflected portion of the inner support surface of the seal expands into the relief area during assembly. 9 . The method of claim 8 , wherein the relief area is formed in a medial area of bottom support surface of the seal gland. 10 . The method of claim 8 , wherein the inner support surface of the seal extends on both sides of the relief area on the bottom support surface. 11 . The method of claim 8 , wherein the relief area has a parabolic form in cross-section. 12 . The method of claim 8 , wherein the second part includes a lead-in area, and the method further includes the lead-in area compressing the seal during assembly of the first and second parts. 13 . The method of claim 8 , further comprising machining the relief area in the bottom support surface. 14 . The method of claim 8 , wherein the relief area has a volume that is less than about 15% of a volume of the seal.
