Engine component seal assembly and method of sealing a coolant passage from an engine component

摘要

An engine component seal assembly and method of sealing a coolant passage from an engine component are provided. The seal assembly includes a sealing sleeve sized and dimensioned to slip fit into an engine component mounting bore and a retaining ring sized and dimensioned to be axially inserted into the sleeve. The ring contacts the sleeve and applies a radial force sufficient to create an interference fit and to move or yield an interface portion of the sleeve radially outward into sealing abutment against a wall forming the mounting bore to create a secure and reliable annular fluid seal.

1. An engine component seal assembly for insertion in a mounting bore having a longitudinal axis formed in a portion of an engine, comprising:
a sealing sleeve including an outer surface sized and dimensioned to be positionable in the mounting bore adjacent a bore sealing surface, said sealing sleeve further including an inner surface having an inner diameter at a ring interface portion; and a retaining ring sized and dimensioned to be positionable within said sealing sleeve adjacent said ring interface portion, said retaining ring having an outer annular surface with an outer diameter, wherein the outer diameter of the retaining ring is greater than the inner diameter of said sealing sleeve before the retaining ring is positioned within the sealing sleeve such that the outer annular surface of the retaining ring applies a radially outward sealing force against said interface portion to create a fluid seal between said sealing sleeve and the bore sealing surface when the retaining ring is positioned within the sealing sleeve.
