ABSTRACT:
A refrigerant assembly includes a refrigerant housing for receiving and containing refrigerant. In one embodiment, the housing has an upper end cap extending over and covering an open upper end of the housing to define a central cavity for the refrigerant. The upper end cap has a bore extending from an inner surface of the end cap to the outer surface. A pick-up tube extends inwardly into the bore from the inner surface of the end cap and is dimensioned so as to be closely received therein. The pick-up tube includes an annular bead toward its outlet end which is received within a counterbore formed coaxial with the bore from the inner surface of the end cap. The counterbore is dimensioned to closely receive the bead on the pick-up tube. The inner surface of the end cap surrounding the counterbore is then mechanically deformed, preferably by staking, around the entire circumference of the pick-up tube such that end cap material is forced radially inward toward the tube. The end cap material at least partially encloses the pick-up tube bead within the counterbore to secure the pick-up tube to the end cap. Moreover, a sharp edge between the counterbore and bore is forced against the junction between the bead and the pick-up tube to provide a fluid tight seal.
