Abstract:
A coupling for sealingly connecting two components, the coupling comprising:a male protruding portion attached to one of the components, the male protruding portion having an axis and a bore extending axially through the male protruding portion, the male protruding portion comprising a tip at one end with a first stop surface, a frustum portion extending from the tip, a first flange portion opposite the tip with respect to the frustum, the frustum having an annular primary sealing surface thereon; and a receiving portion attached to the other of the components, the receiving portion configured for receiving the male protruding portion; the receiving portion comprising a body portion and a second flange portion, the second flange portion having a stop surface cooperative to the second stop surface of the male protruding portion, the receiving portion having an axis perpendicular to the flange portion, a recess and a bore, the recess extending axially from the flange portion and having a periphery with an intermediate portion that converges inwardly toward the bore, the intermediate portion having an inwardly projecting annular ring integral with the receiving portion, the receiving portion further having a stop surface in the recess adjacent to the bore for cooperating with the first stop surface; the male protruding portion assemblable with the receiving portion such that the annular ring confronts the annular primary sealing surface of the male protruding portion, and whereby as the male protruding portion is clamped to the receiving portion, the inwardly projecting annular ring is subjected to a compressive force in an oblique direction with respect to the axis of the protruding portion and the coupling having a fully engaged position wherein the first stop surface is engaged with the first cooperating stop surface of the receiving portion and the second stop surface is engaged with the second cooperating stop surface of the receiving portion.
