Abstract
A tire-pressure adjusting device for a vehicle tire inflation system distributes a compressed-air supply to a plurality of pneumatic apparatuses each comprising a rotary transmitter and measures the tire pressures of vehicle tires connected to the rotary transmitters. The tire-pressure adjusting device includes a control apparatus for receiving a pressure measurement signal and for outputting control signals and a modulation valve apparatus for receiving the control signals and for pneumatically activating one of a plurality of connected rotary transmitters in order to fill and to measure the pressure of at least one vehicle tire connected to the rotary transmitter. The modulation valve apparatus includes a rotary valve, which has a control element that can be rotated into a plurality of rotational positions. The control element activates one of the plurality of pneumatic apparatuses in each of the rotational positions of the control element.
