Abstract: A tire pressure controlling device for a tire of a vehicle wheel filled with compressed air, includes a control valve unit for filling the tire with compressed air and/or venting compressed air therefrom. The control valve unit is supplied from a compressor for generating the tire filling pressure. The compressor for compressing air drawn in from the atmosphere is driven by the mechanical rotary movement of the vehicle wheel, as a transmission disposed therebetween transmits the rotary driving movement of the vehicle wheel to the drive shaft of the compressor unit.

Abstract: A device for adapting actual tire pressure of a tire of a wheel of a vehicle axle to a current setpoint tire pressure during travel includes a chassis-side central device and a wheel-related pneumatic pressure-control device. The pressure control device includes a second connection which is at the actual tire pressure. A control valve with an open position connects a first connection to the second connection, and with a blocking position blocks this connection. A pilot control valve performs pilot control of the control valve. The pressure control device also has a bypass line, which bypasses the control valve and the pilot control valve, connects the first connection to the second connection, and has a non-return valve which opens in the inflation direction of the tire and blocks in the deflation direction of the tire.
