Method of Making a Metal Bellows Assembly Having an Intermediate Plate

摘要: The formation of a bellows made up stack predetermined number ring-convolutions and having an intermediate plate supported within said is achieved by supplying several thin metal rings, each inner outer edges. A pair these rings are positioned in contiguous relationship their adjacent inside edges welded together to form ring-convolution. This process repeated until sufficient eventually make the desired bellows. Before separate fused other, support ring made. disc that sized smaller than diameter secured ring. then between two formed three abutting outside other convolution. already convolution stacked order relationship. All not-yet bottom edge bottommost ring-convolution top finally uppermost complete meant be base infusion pump.
