Temperature adaptive dynamic shaft seal assembly |
摘要 |
A seal assembly configured for sealing a dynamic shaft includes an elastic seal member disposable in sealing communication with the dynamic shaft. The seal assembly further includes a coil spring and a shape memory alloy element. The coil spring is disposed in contact with the elastic seal member and configured for applying a compressive force to the elastic seal member. The shape memory alloy element is configured for applying pressure to the coil spring to thereby augment the compressive force.
