Abstract

A system may include a first member, a second member, a gasket and a pressurized fluid. The first member may include a first recess. The second member may include a second recess adjacently opposing the first recess. The second member may matingly engage the first member and may define a volume therebetween. The gasket may include a cross section having opposing first and second legs and a central portion disposed therebetween. The first leg may be received in the first recess. The second leg may be received in the second recess. The pressurized fluid may be disposed between the first and second legs and may urge the first and second legs into sealing engagement with the first and second recesses, respectively.

Claims (28)

1 . A system comprising:

a first member including a first recess;

a second member including a second recess adjacently opposing said first recess, said second member matingly engaging said first member and defining a volume therebetween;

a gasket including a cross section having opposing first and second legs and a central portion disposed therebetween, said first leg received in said first recess, said second leg received in said second recess; and

a pressurized fluid disposed between said first and second legs and urging said first and second legs into sealing engagement with said first and second recesses, respectively.

2 . The system of claim 1 , wherein said gasket includes an annular member.

3 . The system of claim 1 , wherein said first and second legs and said central portion cooperate to form a generally U-shape.

4 . The system of claim 1 , wherein said gasket includes a radially inner surface area and a radially outer surface area that is smaller than said radially inner surface area.

5 . The system of claim 1 , wherein said first and second recesses cooperate to form a generally U-shaped cross section.

6 . The system of claim 1 , further comprising a fastener engaging said first and second members and urging said first and second recesses into sealed engagement with said first and second legs.

7 . The system of claim 1 , wherein said gasket includes a spring member biasing said first leg into engagement with said first recess.

8 . The system of claim 7 , wherein said spring member extends through at least a portion of said first leg, said central portion and said second leg and biases said first and second legs away from each other and into sealed engagement with said first and second recesses, respectively.

9 . The system of claim 1 , wherein said gasket is integrally formed with a plurality of other gaskets including cross sections having opposing first and second legs and central portions disposed therebetween.

10 . The system of claim 1 , wherein one of said first and second members includes an engine cylinder block and another of said first and second members includes an engine cylinder head.

11 . An apparatus comprising:

a first member including a first recess;

a second member cooperating with said first member to define a cavity therebetween and including a second recess disposed adjacent said first recess; and

an annular gasket including a substantially U-shaped cross section having first and second legs and a central portion disposed therebetween, said first and second legs engaging said first and second recesses, respectively,

wherein a fluid-pressure differential between a first fluid inside of said cavity and a second fluid outside of said cavity urges said first and second legs into sealed engagement with said first and second recesses, respectively.

12 . The apparatus of claim 11 , wherein said gasket includes a radially inner surface area and a radially outer surface area that is smaller than said radially inner surface area.

13 . The apparatus of claim 11 , wherein said first and second recesses cooperate to form a generally U-shaped cross section.

14 . The apparatus of claim 11 , further comprising a fastener engaging said first and second members and urging said first and second recesses into sealed engagement with said first and second legs.

15 . The apparatus of claim 11 , wherein said gasket includes a spring member biasing said first leg into engagement with said first recess.

16 . The apparatus of claim 15 , wherein said spring member extends through at least a portion of said first leg, said central portion and said second leg and biases said first and second legs away from each other and into sealed engagement with said first and second recesses, respectively.

17 . The apparatus of claim 11 , wherein said gasket is integrally formed with a plurality of other gaskets including cross sections having opposing first and second legs and central portions disposed therebetween.

18 . The apparatus of claim 11 , wherein one of said first and second members includes an engine cylinder block and another of said first and second members includes an engine cylinder head.

19 . The apparatus of claim 11 , wherein said first fluid includes at least one of air, fuel, and exhaust gas.

20 . The apparatus of claim 19 , wherein said second fluid includes ambient air.
