1. A shock absorber device comprising:
a first cylinder;
a second cylinder surrounding at least a portion of said first cylinder;
a piston dividing said first cylinder into first and second chambers;
a main rod supporting said piston for movement within said first cylinder, said main rod including a central bore extending
axially along a length of said main rod;
a piston rod adapter coupled to said piston, said piston rod adapter including a body portion extending into said central
bore of said main rod, said body portion including a plurality of radial holes;
an adjuster rod received within said central bore and having a first rod end portion extending toward said piston and a second
rod end portion extending toward a rod end mount; and
a pneumatic actuator cooperating with said second rod end portion to move said adjuster rod within said central bore to a
desired adjuster rod position to adjust damping forces, said pneumatic actuator comprising a plunger having a base portion
received within said rod end mount and a reduced body portion extending outwardly from said base portion toward said adjuster
rod, wherein said pneumatic actuator adjusts damping forces by moving said adjuster rod to cover and uncover said plurality
of radial holes.
