ABSTRACT:
An oscillation damper is provided with a by-pass that includes a by-pass valve. The by-pass valve is switchable between an open position and a closed position. When the by-pass valve is moved between the open and closed positions, the rate of change of the cross-sectional area of the by-pass valve during the time when the by-pass valve is adjacent the closed position is considerably less than the average rate of change of the cross-sectional area during the entire time that it takes for the by-pass valve to switch between the open and closed positions.
