Abstract
A rotary valve plate adapted for housing within a conduit employs a vibration absorbing bumper pad coupled to the valve plate at a surface thereof adapted to contact an inner surface of the conduit whenever the valve plate is rotated to a closed position. The bumper pad minimizes vibratory noise and improves the durability of the valve plate over extended periods of operation.
