ABSTRACT:
A coupling assembly component is used in a coupling assembly to transmit force between driving and driven elements. The coupling assembly component includes an annular tube which is radially extensible and retractable to move a friction surface into and out of engagement with another coupling component. The tube includes a reinforcing layer which is enclosed by a cover layer. A plurality of vent openings are formed in and extend through the cover layer to the reinforcing layer. In one embodiment of the invention, the vent openings are formed in bodies of porous polymeric material disposed in the cover layer. The bodies of porous polymeric material have an inner side exposed to the reinforcing layer and an outer side which is exposed to the atmosphere around the tube. In another embodiment of the invention, vent valves are provided to enable fluid to flow outwardly from the reinforcing layer through the cover layer to the atmosphere around the tube and to prevent contaminants from flowing inwardly from the atmosphere around the tube.
