Fluid seal assembly for a pressured system
Abstract:
The present invention involves a fluid seal assembly of a pressured system for reducing static friction on a displacement rod of the pressured system. The assembly comprises a sealing member disposed on a surface of the pressured system. The sealing member is in circumferential engagement about the displacement rod to define a radial preload on the displacement rod forming a static friction thereon. The assembly further comprises an actuator attached to the sealing member and being configured to bend when the electric input is applied thereacross to displace the sealing member from the displacement rod for reducing the static friction on the displacement rod when the displacement rod move from a stagnant position within the pressured system.
