RTV-less gasket assembly

A gasket assembly comprising:

• a first gasket having a major surface, a contact area of said major surface including an array of geometrical peaks and valleys each having a plurality of planar faces, said peaks and valleys being periodic in a first direction and in a second direction at an angle to said first direction;
• and
• a second gasket having an end surface, a major surface and a thickness, said end surface having an area substantially smaller than said major surface of said second gasket, a contact area of said end surface including an array of geometrical peaks and valleys having planar faces which is periodic in said first and second directions, said second direction having a component parallel to said thickness, said peaks and valleys of said first gasket juxtaposed and adapted to sealingly mate with respective valleys and peaks of said second gasket to provide a sealed joint.

In a vehicle engine including first, second and third component having abutting end faces to be secured together, a sealing structure comprising:

• a first gasket interposed between said first and second components, said first gasket including an end surface, a contact area of said end surface including an array of peaks and valleys which is periodic in a first direction and in a second direction at an angle to said first direction;
• and
• a second gasket having a major surface interposed between said third component and said first and second components, said major surface having an area substantially larger than said end surface, a contact area of said major surface including an array of peaks and valleys which is periodic in said first and second directions, said peaks and valleys of said second gasket being juxtaposed and adapted to sealingly and matingly engage with said valleys and peaks of said first gasket to provide a sealed joint.
