ABSTRACT:
A suspension system according to the present invention comprises a cylinder piston mechanism and a sub-tank. A main gas chamber is defined inside the cylinder piston mechanism, while a sub-gas chamber is defined inside the sub-tank. An oil chamber, filled with oil, and an oil passage are arranged between the main and sub-gas chambers. The oil passage is opened and closed by means of a control valve, which has a rotating valve plug for controlling the oil flow. When the control valve is open, the main and sub-gas chambers change their respective capacities simultaneously as a rod reciprocates. When the valve is closed, only the main gas chamber changes its capacity as the rod reciprocates. The control valve is provided with a spring-constant changing orifice and a damping-force changing orifice, whereby the spring constant and damping force of the system are changed simultaneously, in accordance with the rotational position of the valve plug.
