ABSTRACT:
An apparatus for attenuating noise produced by fluid pressure pulsations in a hydraulic system in an automotive vehicle is disclosed. The apparatus includes a muffler device comprising a generally elongate tubular member having a predetermined number of attenuating zones therein, each zone having a cross-sectional area of different size than the cross-sectional area of the tubular member. The attenuating zones are spaced at unequal lengths from one another to achieve maximized noise reduction benefits.
