assembly. Fluid pressure is applied to the forward side
of the buffer pistons; and the pistons, piston rods, and
slide assembly move aft. As the pistons move aft, fluid
is forced out of the aft end of the buffer cylinder
assembly, through a check valve and the other flow
control valve, to the gravity tank.
