Abstract
Sealing gasket construction for providing a fluid seal intermediate a pair of opposed, mating parts or structures, one of the parts having an edge and a void space defined along the edge. The gasket includes a retainer and a resilient seal element having a wedging portion extending radially beyond one of the retainer inner or outer perimeter. The wedging portion is configured in a free state to extend into the area of the void space and to be wedged against the other one of the interfacing parts, and thereby made to occupy at least a portion of the void space.
Claims26
A gasket for interposition between a first and a second interfacing surface, one of the interfacing surfaces having an edge and a void space defined therealong, the gasket comprising:
- a retainer having an inner perimeter and an outer perimeter, and having opposing first and second radial faces each extending in a radial direction intermediate the inner and outer perimeter;
- and
- a generally annular first seal element supported on the retainer to extend radially beyond one of the retainer inner or outer perimeter, the first seal element having an inboard sealing portion extending along at least a portion of the one of the retainer inner or outer perimeter and an outboard wedging portion extending along at least a portion of the sealing portion and having an inboard side disposed adjacent the sealing portion and an outboard side, the sealing portion being configured in a free state to be compressible in an axial direction generally normal to the radial direction intermediate the interfacing surfaces into an energized state effecting a seal therebetween, and the outboard side of the wedging portion being configured in a free state to extend into the area of the void space along the edge of the one of the interfacing surface and to be wedged against the other one of the interfacing surfaces and thereby made to occupy at least a portion of the void space.
A sealing assembly comprising:
- a first and a second interfacing surface, one of the interfacing surfaces having an edge and a void space defined therealong;
- and
- a gasket interposable between the interfacing surfaces, the gasket comprising:
- a retainer having an inner perimeter and an outer perimeter, and having opposing first and second radial faces each extending in a radial direction intermediate the inner and outer perimeter;
- and
- a generally annular first seal element supported on the retainer to extend radially beyond one of the retainer inner or outer perimeter, the first seal element having an inboard sealing portion extending along at least a portion of the one of the retainer inner or outer perimeter and an outboard wedging portion extending along at least a portion of the sealing portion and having an inboard side disposed adjacent the sealing portion and an outboard side, the sealing portion being configured in a free state to be compressible in an axial direction generally normal to the radial direction intermediate the interfacing surfaces into an energized state effecting a seal therebetween, and the outboard side of the wedging portion being configured in a free state to extend into the area of the void space along the edge of the one of the interfacing surface and to be wedged against the other one of the interfacing surfaces and thereby made to occupy at least a portion of the void space.
