- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: NASA Goddard Space Flight Center has developed a hermetically sealed normally-closed (NC) zero leak valve. Prior to actuation, the valve isolates upstream working fluid from the downstream volume with a parent metal seal. The valve utilizes the magnetorestrictive alloy Terfenol-D for near instant actuation. Terfenol-D undergoes magnetostriction, or gross elongation, when exposed to a magnetic field. This fractures the seal and opens the valve permanently to establish fluid flow. The valve consists of two major sub-assemblies: the actuator and the flow cavity. The actuator is preloaded to 1,250 N by adjusting the preload bolt, pressing the Terfenol-D against the now-deflected belleville springs. When actuation is needed, either solenoid coil is charged in a pulsed mode, causing magnetostriction or elongation in the Terfenol-D which deflects the belleville spring stack, supplying an increasing load to the stem until the parent metal seal is fractured. Once fractured, the spring inside the bellows drives the bellows base downward, onto a raised boss at the top of the fracture plate. When fracture has occurred, the stem and its spring stack is left, separated from the actuator column. The Terfenol-D is unloaded and returns to its original length. The valve remains open due to the spring inside the bellows. To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/GSC-TOPS-106 If you have any questions, please e-mail NASA�s Technology Transfer Program at Agency-Patent-Licensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this SAM.gov notice and your preferred contact information. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. No follow-on procurement is expected to result from responses to this Notice.
