ABSTRACT:
A control valve for increasing or reducing the air pressure in a tire of a vehicle wheel that is to be carried out over a short period of time, has a valve chamber that is connected, on one side, to the interior of the tire and, on the other side, to a supply duct. The valve chamber has a space that extends axially through the wheel hub, the interior end of this space being sealed off with respect to an axle part carrying the vehicle wheel. In this space, an automatically closing valve member is arranged that can be controlled into its open position against the interior pressure of the tire by a control piston that is also guided in this space and can be acted upon by a pressure medium. For supplying air to and removing air from the tire, the axle part projects into an axial duct of the control piston with a cylindrical projection that is penetrated by the supply duct. For the opening of the control valve for the removal of air and, if necessary, also for supplying air to the tire, the pressure medium is supplied via a supply duct provided in the axle part and leading out into an intermediate space located between the axle part and the control piston.
