摘要

The valve device (20) has an electronic pneumatic suspension device (10) including several magnetic valves (11-13) to pressurize and evacuate the carrier bellows (1, 1'). The downstream pressure connections (16, 16', 16) of the valve device are pneumatically connected to the magnetic valves. The valve device includes operating elements (21-23) in the form of pneumatic valves.
