Patent number: 6053992Abstract: A mechanism that uses the shape recovery of a shape memory alloy for sealing openings or high pressure passages. A component made of a shape memory alloy can be processed in its martensitic state to have a reduced dimension smaller than that of the opening or the passage to be sealed. Upon heating, shape recovery takes place which is associated with the reverse crystalline phase transformation of martensite. The shape recovery of the previously processed shape memory alloy component yields a diameter which is greater than that of the opening or passage to be sealed. The shape recovery provides the dimensional interference and force required for sealing.Type: GrantFiled: September 30, 1997Date of Patent: April 25, 2000Assignee: Memry CorporationInventors: Ming H. Wu, L. McD. Schetky
