Abstract

PURPOSE:To prevent the sudden lowering of pressure caused by the movement of excessive extension of a cylinder and a hollow rod by providing a staged part on the periphery of a piston on the side of the first hydraulic chamber for making an orifice work in relation to the inner face of an inner cylinder. CONSTITUTION:The first hydraulic chamber 6 is connected to the first pressure accumulation chamber 8, while the second hydraulic chamber 7 is connected to the second pressure accumulation chamber 10. When a hollow rod 5 is excessively extended in relation to a cylinder 1, a connecting hole 30 is opened to connect both hydraulic chambers, and since the pressure in the first hydraulic chamber 6 is lowered, the height of a car is reduced. At this stage, since a staged part 4a provided on a piston 4 connected in one body with the hollow rod 5 works as an orifice to the operation liquid flowing in the connecting hole 30, the sudden lowering of pressure is prevented. Consequently, when the car is turned, the function of car- height adjustment is given, and left and right car-heights are steadily balanced.
