Abstract
An accumulator for a vehicle suspension damper includes a housing having an open end connected to an accumulator port on the damper and a distal end opposite the open end including an end wall extending radially inward to a charge port. A bellows assembly including an annular bellows wall extending between a proximal plate and a distal plate is positioned within the housing to define a pressurized gas chamber within the accumulator arranged in fluid communication with the charge port. The charge port includes a stem extending inward from the end wall of the housing and the distal plate of the bellows assembly has an inner diameter received on the stem. The inner diameter of the distal plate is coupled to the stem of the charge port by a securing member.
