Abstract
A volume compensation accumulator apparatus connected to a conduit connecting hydraulic cylinders in a suspension system. The volume compensation accumulator apparatus includes an arrangement of the two orifice plates in series in a spaced-apart relation, which eliminates the necessity of reducing the diameters of the orifices while providing the same orifice characteristic as that of an orifice having a smaller diameter, thereby making the boring process of the orifice easy, and reducing clogging of the orifices with foreign objects.
