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.

摘要： A method of assembling an accumulator for a suspension damper where the method includes the steps of forming an outer shell of an accumulator, assembling a bellows assembly by connecting distal and proximal plates to opposite ends of an annular bellows wall, and inserting the bellows assembly into the outer shell. The outer shell is formed such that it includes a distal end with an end wall and an open end opposite the distal end. The bellows assembly is inserted into the open end of the outer shell with the distal plate facing the end wall of the outer shell. The method proceeds with coupling the distal plate of the bellows assembly to a stem of a gas charging port on the end wall of the outer shell at a fixed axial position using a fixation component that engages the stem of the gas charging port.

摘要： An accumulator for a vehicle suspension damper, which includes an outer shell with an open end that connects to an accumulator port on the damper and a distal end, opposite the open end, which includes an end wall that extends radially inward to a gas charging port. A bellows assembly, which includes an annular bellows wall extending between proximal and distal plates, is positioned inside the outer shell to define a pressurized gas chamber inside the accumulator that is arranged in fluid communication with the gas charging port. The gas charging port includes a stem that extends inwardly from the end wall of the outer shell and the distal plate of the bellows assembly has an inner diameter that is received on the stem. The inner diameter of the distal plate is coupled to the stem of the gas charging port by a fixation component.
