Abstract
PURPOSE: To simultaneously control the damping force on the elongation side and on the contract side by a single valve by providing a valve, the valve opening pressure of which is increased and decreased according to an exciting current. CONSTITUTION: As a first valve 15 is closed on the elongation stroke, operating oil of an oil chamber A on the contracted piston rod 12 side passes through a circulating path 22 to force a second valve 26 open, and flows into a compensating path 24. On the other hand, on the contract stroke, operating oil of an oil chamber B on the contracted piston 11 side forces the valve 15 open to flow in the oil chamber A on the enlarged piston rod 12 side, and further operating oil corresponding to a receive volume of the piston rod 12 passes through the circulating path 22 to force the valve 26 open, and flows into the compensating path 24. In this arrangement, the valve opening pressure of the valve 26 can be adjusted according to an exciting current to a solenoid 28. Therefore, according to the operating condition, the solenoid exciting current is controlled to freely adjust the damping force on the elongation side and on the contract side at the same time to be increased or decreased by the single valve 26.
