Abstract
A seal for sealing between a first component and a second component includes a first metallic element comprising a plurality of sealing profiles and defining a groove therein and a second metallic element comprising a plurality of sealing profiles and a protrusion mated with the groove of the first metallic element. The seal further includes a retaining member engaged with the second metallic element and capable of being engaged with one of the first component and the second component for retaining the first and second metallic elements in a position, wherein some of the plurality of sealing profiles are capable of sealing against the first component and some of the plurality of sealing profiles are capable of sealing against the second component.
Claims27
A seal for sealing between a first component and a second component, comprising:
- a first metallic element comprising a plurality of sealing profiles and defining a groove therein;
- a second metallic element comprising a plurality of sealing profiles and a protrusion mated with the groove of the first metallic element;
- and
- a retaining member engaged with the second metallic element and capable of being engaged with one of the first component and the second component for retaining the first and second metallic elements in a position,
- wherein some of the plurality of sealing profiles are capable of sealing against the first component and some of the plurality of sealing profiles are capable of sealing against the second component.
A seal for sealing between a first component and a second component, comprising:
- a center metallic element comprising a plurality of sealing profiles and defining a first groove and a second groove therein;
- a first metallic element comprising a plurality of sealing profiles and a protrusion mated with the first groove of the center metallic element;
- a second metallic element comprising a plurality of sealing profiles and a protrusion mated with the second groove of the center metallic element;
- and
- a retaining member capable of being engaged with one of the first component and the second component for retaining the first metallic element, the center metallic element, and the second metallic element in a position.
A method of sealing between a first component and a second component, comprising:
- applying a fluid pressure to a first metallic element;
- urging a plurality of sealing profiles of the first metallic element against the first component and the second component;
- urging the first metallic element against a second metallic element;
- and
- urging a plurality of sealing profiles of the second metallic element against the first component and the second component.
A method of sealing between a first component and a second component, comprising:
- applying a fluid pressure in a first direction to a first metallic element;
- urging a plurality of sealing profiles of the first metallic element against the first component and the second component to inhibit a flow of fluid therebetween in the first direction;
- urging a first set of a plurality of sealing profiles of a second metallic element against the first component and the second component to inhibit a flow of fluid therebetween in the first direction;
- applying a fluid pressure in a second direction that is different from the first direction to a third metallic element;
- urging a plurality of sealing profiles of the third metallic element against the first component and the second component to inhibit a flow of fluid therebetween in the second direction;
- and
- urging a second set of the plurality of sealing profiles of the second metallic element against the first component and the second component to inhibit the flow of fluid therebetween in the second direction.
