Pneumatic suspension unit for vehicles with individual regulation and only one pressure sensor

The valve block (2) for inflating the bellows (6, 10, 36, 40) includes a valve device (14) capable of simultaneously disconnecting the bellows valves (16, 18, 24, 42, 44, 46) from the compressed air tank (12) and venting point (15). A sensor (22) is provided for measuring air pressure in the air flow path (20) between the valve device and bellows valves. The valve block allows individual bellows or groups of bellows to be inflated and deflated.
