A self-pumping hydropneumatic macpherson strut unit with an inner level control is provided to control the level of a vehicle by forming a valve for passing oil from a high-pressure chamber to a low-pressure chamber. A self-pumping hydropneumatic macpherson strut unit with an inner level control comprises a working cylinder(8), and a reciprocating pump(9). The working cylinder is divided into two working cylinders by a working piston supported by a hollow piston rod and filled with oil by pressure of more than one gas padding placed in a high-pressure chamber and operated by a spring. The reciprocating pump driven by spring movement has a flow connecting(33) for connecting the high-pressure chamber with a low-pressure chamber(3) and transfers the oil to the working chamber connected to the high-pressure chamber from the low-pressure chamber. The flow connecting includes a valve(16) opened by the pressure. The valve passes the oil from the high-pressure chamber to the low-pressure chamber. |
