ABSTRACT:
A pressure vessel (1) includes a pair of shells (2,3) which are suitably joined together. A flexible diaphragm (12) is disposed within the vessel and sealingly mounted to the vessel walls adjacent the joint. The lower shell wall (5) has a radially outwardly extending offset (17) and bulge (19) forming an interior groove (20) for receiving a projection (16) on the diaphragm. The bulge merges into an inwardly tapered wall (21) which in turn merges into an axial cylindrical wall (23) having a terminus edge (24). The upper shell wall (4) has a pair of spaced radially inwardly extending offsets (25,28). The upper (25) of said pair of offsets provides an abutment (26) receiving the terminus edge (24) of the lower shell. An axial cylindrical wall (29) between the pair of inward offsets press-fittingly engages the upper edge portion (23) of the lower shell. A further cylindrical wall (30) extends downwardly from the lower (28) of said pair of offsets and compressingly engages the diaphragm (12) so that it tends to ride down the inclined ramp-like tapered wall (21) and tightens into the groove (20) during assembly. The further cylindrical wall (30) merges into an inwardly tapered protective lip (32).
