Abstract:
1. A flexible flow control bushing, comprising a flexible, high temperature resistant, self-lubricating composite material, having a configuration in the elongated position prior to installation, of a squared-off sine wave cross section with equally, spaced nodes forming opposed recesses in the bushing on the opposed faces thereof, and, when the cross-section is laid flat, is defined by a top periphery and, a bottom periphery, the top periphery and the bottom periphery both being shaped like square waves having alternating nodes and recesses when viewed from the side, and that the square waves are offset so that the nodes of one wave overlap the recesses of the other and vice versa, the entire cross-section when viewed from the side approximating a square wave so that nodes of the square wave of one periphery fully overlap recesses of the square wave of the other periphery and vice versa, one side of the bushing being provided with a generally central elongated groove which extends through the top periphery and partially into the opposing, recess.
