ABSTRACT:
A method of permanently uniting two cylindrical members with mating end edges which cooperate to define a circumferential groove that is closed except for a continuous inner circumferential slot defined by the end edges. In the method, the mating end edges of the two members are brought together to imprison the peripheral bead of a flexible diaphragm under axial compression in the circumferential groove so that the web of the diaphragm extends through the continuous circumferential slot. The two cylindrical members are then held together under pressure while a cap with a cylindrical skirt is telescoped onto one member past the joint between its mating edge and that of the other member. Prior to this telescoping step, the inner wall of the skirt is coated with a suitable adhesive to provide an adhesive layer between the confronting skirt and cylindrical wall areas of the final assembly. The two cylindrical members are maintained under pressure until the adhesive sets, after which the pressure is released. The cylindrical members are now held tightly together, with the bead of the diaphragm under axial compression in the circumferential groove formed by their mating end edges, by the adhesive bond between them and the cap.
