ABSTRACT:
A pressure vessel suitable for use in an automotive air-conditioning system includes a cylindrical body (10, 40) including an annular wall (14, 44). The cylindrical body preferably includes an opposite closed end, an initially opened end (12, 42), and a closure member (20, 50) inserted into the open end of the cylindrical body. The closure member and the cylindrical body each have extensions or annular flanges (28, 58) which are spin welded together. The cylindrical body is fused to the closure member when the annular flange (28, 58) of the closure member is spin welded to an annular, outermost portion (18, 48) of the cylindrical body. The closure member and the cylindrical body are further locked together by inwardly rolling a portion of the annular wall into an annular groove (30, 60) and an outermost surface of the closure member.
