Swivelable quick connector for high temperature connection

A high-temperature connector assembly for a vehicular emissions exhaust system comprising:

• an engine exhaust port which is formed having an axial bore for providing a fluid path through said engine, said bore having a first diameter portion, an enlarged second diameter portion adjacent to the first diameter portion, and a third diameter portion adjacent to the second diameter portion having a magnitude less than the first diameter portion;
• a tubular conduit adapted to convey fluid having outwardly projecting annular surface means formed at a predetermined distance from an end of said conduit to be connected for providing a blocking wall portion disposed transversely to a central axis of said conduit;
• metallic sealing means disposed in said bore means, said sealing means including a pair of substantially concentric walls, said walls being responsive to fluid passing through said conduit and said engine for providing a seal between one of said walls and said conduit and between the other of said walls and said engine exhaust port;
• and
• retaining means demountably coupled to said first port of said engine for cooperating with said blocking wall portion of said annular surface means to resist the disconnection of said conduit from said engine exhaust port and for abutting and positioning said sealing means within said engine exhaust port, said retaining means including a substantially planar annular disk member having a first and second surface and one or more arm members extending from said annular member, said annular member having said first surface adapted to abut and position said metallic seal means in said axial bore and said second surface adapted to abut said outwardly projecting annular surface means, said end of said conduit adapted to pass through said annular disk member and said metallic sealing means into said third diameter portion of said axial bore of said exhaust port to convey fluid between said conduit and said engine, said one or more arm members including means for retaining said outwardly projecting annular surface means in said one or more arm members and said one or more arm members including a means for cooperating with said exhaust port second diameter portion to resist the disconnection of said conduit from said fixture.

A high-temperature connnector assembly for providing swivelable quick connection capable of transferring a high-temperature fluid, comprising:

• a metallic tubular conduit adapted to convey a high-temperature fluid and having an outwardly projecting annular shoulder formed at a predetermined distance from the forward end thereof,
• a metallic fixture having an axial bore formed therein for receiving said conduit and providing a fluid path for passing said high-temperature fluid,
• a thermally responsive, resilient metallic seal means disposed in said axial bore and primarily adapted to undergo radial changes in shape for engaging and providing a 360.degree. fluid-tight seal and thermal path between and around said conduit and said fixture, said seal means, fixture and conduit being responsive to changes in temperature caused by the fluid such that each may undergo a different expansion or contraction due to the change in temperature while the seal means retains its fluid-tight seal, and
• releasable retaining means connected to said annular shoulder for abutting and positioning said seal means in said fixture and for resisting the unwanted withdrawal of said conduit from said fixture, said retaining means including a substantially planar annular disk member having a first and second surface and one or more arm members extending from said annular member, said annular member having said first surface adapted to abut and position said metallic seal means in said axial bore and said second surface adapted to abut said outwardly projecting annular shoulder, said end of said conduit adapted to pass through said annular disk member and said metallic sealing means into said axial bore of said fixture to convey high-temperature fluid between said conduit and said fixture, said one or more arm members including means for retaining said outwardly projecting annular shoulder in said one or more arm members and said one or more arm members including a means for cooperating with said fixture axial bore to resist the disconnection of said conduit from said fixture.
