Coupling assembly component

摘要

A coupling assembly component includes an annular base. A first annular friction surface is connected with the base and is movable into engagement with a second annular friction surface. An annular fluid extensible tube is inflatable to move the first friction surface into engagement with the second friction surface. A fitting is connected with the base and the tube to conduct fluid pressure into a chamber in the tube. An annular mounting ring is disposed in a coaxial relationship with the base and the tube. The annular mounting ring is embedded in the tube and is connected with a portion of the fitting. The annular mounting ring may be provided with only a single opening which is connected with a fitting through which fluid is conducted into the tube. However, the annular mounting ring may be provided with a plurality of openings connected with a plurality of fittings.
