HYDROPNEUMATIC Suspension: Description

The hydropneumatic suspension is a gas pressure suspension system with hydraulic level control. The vehicle load is supported by four struts, which also serve as shock absorbers. Suspension is accomplished by the compression and decompression of the gas cushion in the pressure reservoirs. To regulate the vehicle level, the oil volume in the suspension struts is increased or reduced by means of a hydraulic system. The hydraulic system is comprised of; oil pump, pressure regulator, main pressure reservoir and oil reservoir. The pressure regulator and level selector valve are combined into one valve unit.
