Abstract
A tire pressure regulating unit for modifying the air pressure in vehicle tires while traveling. Shutters, which are arranged between the tire and the tire control valve, have parallel-connected auxiliary valves which release an additional passage cross-section when the regulation pressure decreases. The shutters may also be provided on the other side of the tire control valve in the work line in the region of the wheel hub, with rapid release valves being connected in parallel to the shutters and permitting bleeding to the atmosphere upon a decrease of regulation pressure. In this way short bleeding times are achieved even for low regulation pressures.
