ABSTRACT:
An anti-swish mechanism for a damper is disclosed to reduce the swish noise heard during movement of a piston assembly within the damper. The damper includes a pressure cylinder which forms a working chamber having a first portion and a second portion operable to store damping fluid. A piston rod is partially disposed within a pressure cylinder and a piston body is secured within the piston rod. Extending from the piston body are first and second annular axially extending lands which are concentric with the piston body. A set of axially extending, circumferentially spaced flow ports are formed in the piston body between the first and second annular axially extending lands. Adjacent to the flow ports is an anti-swish mechanism which reduces "swish" noise as the piston body moves within the pressure cylinder.
