Abstract
A noise reducer for a valve having a quick release function is disclosed. The noise reducer is preferably an open-celled structure that is impervious to dirt, moisture, alcohol, and oil, and acts as both a dampener and a biasing spring to reduce the oscillations of an exhaust diaphragm in an ABS modulator and urge the diaphragm toward a closed position. The open-celled foam is preferably an annular configuration so that it does not interfere with the amplitude of displacement of the diaphragm.
