Pneumatic spring element arrangement has electronic controller for regulating quantity of air in spring element using regulating valve depending on flow meter and pressure sensor signals

摘要

The spring element arrangement has a pressure source connected to a spring element (10) via a regulating valve (16), a flow meter (15) between the valve and spring element and an electronic controller (19) for regulating the quantity of air in the spring element using the regulating valve, which also has a venting path, depending on the flow meter signals and those of a pressure sensor for the pressure volume.
