摘要： A bellows accumulator for a vehicle suspension system and related methods of operating the accumulator include inserting a bellows assembly within an outer shell. The bellows assembly includes an annular bellows wall defining a gas chamber of variable volume. An accumulation chamber is provided between the outer shell and the bellows assembly. The method includes operating a valve in fluid communication with the accumulation chamber in an open condition and a closed condition, filling the accumulation chamber with fluid prior to filling the gas chamber with pressurized gas, providing a pressure differential between the pressurized gas chamber and the accumulation chamber to extend the annular bellows wall and operate the valve in the closed condition. The method includes protecting the bellows wall during pre-charging of the pressurized gas chamber as well as during vehicle suspension operation by maintaining fluid between the outer shell and the annular bellows wall.
