ABSTRACT:
A piston and cylinder arrangement, which includes a piston and piston rod assembly and which is filled with a damper-fluid, is attached to an auxiliary tank by a flow channel. A first restriction in the piston and piston rod assembly substantially controls the low velocity flow of the damper fluid during extension strokes and a second restriction in the piston and piston rod assembly substantially controls high velocity flow of the damper fluid during the extension strokes. A third restriction in the flow channel substantially controls the low velocity flow of the damper-fluid during compression strokes, and a fourth restriction in the flow channel substantially controls the high velocity flow of the damper-fluid during the compression strokes. Substantially unrestricted flow of the damper-fluid through the piston and piston rod assembly is permitted during the compression strokes, and substantially unrestricted flow of the damper-fluid through the flow channel is permitted during extension strokes.
