Abstract
A suspension damper for washing machines includes a control rod that is configured to attach a fixed bracket of a washing machine cabinet and a first cap having an aperture through which the control rod slidingly extends. The first cap is configured to engage a concave portion of a bracket on a drum of the washing machine. A second cap is disposed on the control rod, and a spring is disposed between the first cap and the second cap. The first cap includes at least one water passageway for guiding water along an outer surface of the first cap. An umbrella may be disposed on the control rod to shed water outwardly away from the control rod.
