Abstract:
A gasket for use with an internal combustion engine, comprising:a first metal plate having a base portion and a first plate opening that is offset longitudinally downward relative to said base portion, said first plate forming a first portion of a primary combustion seal and a first portion of a secondary combustion seal, said secondary combustion seal being positioned adjacent to said primary combustion seal and radially outwardly from said first plate opening;a second metal plate disposed adjacent said first plate, said second plate having a body portion, an angle arm, an offset portion, a curved portion and a flange, wherein said angled arm is disposed between said body portion and said offset portion and offsets said offset portion longitudinally relative to said body portion, said curved portion defining a second plate opening and extending away from said offset portion, said flange extending away from said curved portion such that said flange is spaced away and generally parallel to said offset portion to form a second portion of said primary combustion seal; anda third metal plate having a third plate opening and forming a second portion of said secondary combustion seal, said third plate positioned adjacent to said second plate such that a portion of said second plate is disposed between said first plate and said third plate, said third plate opening having a diameter larger than that of said second plate opening and positioned such that said third plate is in a non-overlapping orientation with said offset portion of said second plate and said second portion of said secondary combustion seal being positioned adjacent to said third plate opening;wherein said primary combustion seal is offset from said secondary combustion seal to insure equal compression of said second combustion seal and said primary combustion seal when said gasket is operatively positioned between mating components.
