Abstract: 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.

Abstract: 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.

Abstract: A method of pressuring an accumulator including an end cap and a floating piston comprises positions the floating piston outside an inner volume of the end cap. Pressurized gas is supplied to the inner volume through an open end of the end cap. The floating piston is inserted through the open end and sealing engagement with the end cap to define a pressurized gas chamber within the end cap. The method further includes mechanically deforming the end cap to define a radially inwardly extending projection that restricts removal of the floating piston from the end cap.
