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.

Description

technical field [0001] The present disclosure relates to valve discs or plates equipped with shock absorbing cushions. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Many exhaust systems in the automotive field have attempted to use active or passive valve assemblies to alter the characteristics of the exhaust flow through the duct as the exhaust pressure increases due to increasing engine speed. Active valves come with added expense due to the need for specific actuation elements such as solenoids. Passive valves utilize the pressure of the exhaust flow in the conduit associated with the valve. [0004] Traditionally, even less expensive passive valves have caused accelerated wear and rattling noise or rattling when the valve is switched from an open position to a fully closed position in which a portion of the disc is in contact with the inner surface of the pipe th...
