Gasket assembly
View Patent ↗A gasket assembly includes a plurality of carriers. Each carrier has at least one non-sealing aperture and at least one sealing aperture. The sealing aperture has a seal which extends around a perimeter of the sealing aperture and is attached to the carrier. The plurality of carriers comprises a stack of carriers with each of the carriers in the stack being in touching contact with at least one other of the carriers. The non-sealing apertures of the carriers are aligned to and associated with the sealing apertures such that each seal extends through aligned and associated non-sealing apertures in the other carriers to provide a first sealing surface at a first outer surface of the stack and a second sealing surface at a second outer surface of the stack. The carriers in the stack may be joined together to form the gasket assembly. The seals may include various materials, including elastomers, such as those commonly used in automotive vehicle applications.
1. A gasket assembly, comprising a plurality of carriers, each of said carriers having at least one non-sealing aperture and at least one sealing aperture with a seal which extends around a perimeter of the sealing aperture and is attached to the carrier; the plurality of carriers comprising a stack of carriers, each of said carriers in touching contact with at least one other of said carriers with the non-sealing apertures of the carriers aligned to and associated with the sealing apertures such that each seal extends through aligned and associated ones of said non-sealing apertures in the other carriers and provides a first sealing surface at a first outer surface of the stack and a second sealing surface at a second outer surface of the stack.
2. The gasket assembly of claim 1 , further comprising a means for joining the plurality of carriers together to form the stack.
3. A gasket assembly, comprising:
a first carrier having an outer surface, a carrier mating surface, at least one non-sealing aperture, at least one sealing aperture, and at least one first seal which is attached to said first carrier and which extends around a perimeter of the sealing aperture;
a second carrier having an outer surface, a carrier mating surface, at least one non-sealing aperture, at least one sealing aperture, and at least one second seal which is attached to said second carrier and which extends around a perimeter of the sealing aperture; the mating surfaces of said first carrier and said second carrier in touching contact with one another with the at least one non-sealing aperture of said first carrier aligned to and associated with the at least one sealing aperture of said second carrier, and with the at least one non-sealing aperture of said second carrier aligned to and associated with the at least one sealing aperture of said first carrier, the seals each adapted to extend through the respective associated non-sealing aperture and provide a first sealing surface at the outer surface of said first carrier and a second sealing surface at the outer surface of said second carrier.
4. The gasket assembly of claim 3 , wherein the at least one first seal and the at least one second seal are each formed from an elastomeric material.
5. The gasket assembly of claim 3 , wherein the at least one first seal is attached to said first carrier at a sidewall of its at least one sealing aperture and the at least one second seal is attached to said second carrier at a sidewall of its at least one sealing aperture.
6. The gasket assembly of claim 4 , wherein the at least one first seal and the at least one second seal comprise different elastomeric materials.
7. The gasket assembly of claim 4 , wherein the at least one first seal and the at least one second seal comprise the same elastomeric material.
8. The gasket assembly of claim 6 , wherein the gasket assembly is an automotive vehicle gasket assembly.
9. The gasket assembly of claim 8 , wherein the elastomeric material of the first seal and the elastomeric material of the second seal are selected from a group consisting of engine coolant-resistant elastomers, fuel-resistant elastomers, engine oil resistant elastomers, automatic transmission fluid resistant elastomers, refrigerant resistant elastomers and power steering fluid resistant elastomers.
10. The gasket assembly of claim 8 , wherein the elastomeric materials of the at least one first seal and the at least one second seal are selected from a group consisting of FKM, FEPM, ECO, HNBR, VMQ, CR, NBR, ACM, AEM, EVA and EPDM.
11. The gasket assembly of claim 3 , further comprising a means for joining said first carrier to second carrier.
12. The gasket assembly of claim 3 , wherein each of said seals is formed from an elastomeric material.
13. The gasket assembly of claim 3 , wherein each of said seals is attached to a sidewall of its sealing aperture.
14. The gasket assembly of claim 12 , wherein the seal of each of said carriers comprises an elastomeric material which is different from that of the other carriers.
15. The gasket assembly of claim 12 , wherein the seal of each of said carriers comprises the same elastomeric material.
16. The gasket assembly of claim 14 , wherein the gasket assembly is an automotive vehicle gasket assembly.
17. The gasket assembly of claim 16 , wherein the elastomeric material of the first seal and the elastomeric material of the second seal are selected from a group consisting of engine coolant-resistant elastomers, fuel-resistant elastomers, engine oil resistant elastomers, automatic transmission fluid resistant elastomers, refrigerant resistant elastomers and power steering fluid resistant elastomers.
18. The gasket assembly of claim 17 , wherein the elastomeric materials of the at least one first seal and the at least one second seal are selected from a group consisting of FKM, FEPM, ECO, HNBR, VMQ, CR, NBR, ACM, AEM, EVA and EPDM.
