Abstract
A seal for use with a first coupling element and a second coupling element has an annular configuration. The seal has an inner wall and an outer wall. The seal has a first portion, a central portion and a second portion. The central portion extends outwardly of the first portion and the second portion. A channel is formed in the central portion so as to have one end opening to the outer wall at the first portion and an opposite end opening to the outer wall at the second portion. The seal is formed of a metallic material. The outer wall at the central portion has a generally V-shaped configuration.
Claims17
An article for use with a first coupling element and a second coupling element, the article comprising:
- a seal having an annular configuration, said seal having an inner wall and an outer wall, said seal having a first portion and a central portion and a second portion, said central portion extending outwardly of said first portion and said second portion, said seal having a channel formed in said central portion so as to have one end opening to said outer wall at said first portion and an opposite end opening to said outer wall at said second portion, the outer wall at said first portion of said seal having a first surface and a second surface, said first surface extending at an obtuse angle with respect to said second surface, said one end of said channel opening to said second surface, said second surface having a protrusion extending outwardly therefrom, said protrusion suitable for receipt within a notch formed in the first coupling element.
An article for use with a first coupling element and a second coupling element, the article comprising:
- a seal having an annular configuration, said seal having an inner wall and an outer wall, said seal having a first portion and a central portion and a second portion, said central portion extending outwardly of said first portion and said second portion, said seal having a channel formed in said central portion so as to have one end opening to said outer wall at said first portion and an opposite end opening to said outer wall at said second portion, said inner wall of said seal having an arcuate inner surface such that an inner diameter of said seal is greatest in an area corresponding to said central portion.
An apparatus comprising:
- a first coupling element having an interior passageway and an end;
- a second coupling element having an interior passageway and an end;
- and
- a seal positioned in the interior passageways of said first and second coupling elements adjacent the ends of said first and second coupling elements, said seal having a annular configuration, said seal having an inner wall and an outer wall, said seal having a first portion and a central portion and a second portion, said central portion extending outwardly of said first portion and said second portion, the outer wall at said first portion bearing against a wall of said interior passageway of said first coupling element, the outer wall at said second portion bearing against a wall of said interior passageway of said second coupling element, said central portion positioned at the ends of said first and second coupling elements, said first coupler element having a notch formed in a wall of said coupling element surrounding said interior passageway, said outer wall of said seal of said first portion having a protrusion extending outwardly therefrom, said protrusion being received in said notch of said first coupling element.
