Abstract: A pressure medium supply device for a tire of a wheel unit, a wheel unit, and a valve arrangement for a rotationally fixed transition of a pressure medium supply device for a wheel unit are provided. The valve arrangement has a housing part through which a pressure medium can flow, a control piston, in particular an axially movable control piston which is received on the housing part, and a discharge element with an outlet for conducting the pressure medium. The housing part and the discharge element are received in a rotatable manner relative to each other. The control piston has a flow channel for the pressure medium, has a force application surface to which the pressure medium can be applied, and can be moved between a disengaged position and an engaged position. A pressure medium line can be established between the housing part and the discharge element in the engaged position.

Abstract: The invention relates to a distributed system (54) for supplying pressurized medium, in particular compressed air, in a vehicle (10), a wheel unit (14) for a vehicle (10), and a decentralized integrated pressurized medium supply device (70) for a wheel unit (14) with a rotatably supported vehicle tire (16). The pressurized medium supply device (70) has a decentralized compressor unit (74) and has a pressurized medium path (98) that extends between the decentralized compressor unit (74) and a rim body (92) of the vehicle tire (16), which rim body is associated with a wheel body side (80) of the wheel unit (14). The decentralized compressor unit (74) has an energy supply connection, which can be connected to an energy supply unit (104) via an energy supply path (106). The pressurized medium supply device (70) is associated with a support side (82) and the wheel body side (80) of the wheel unit (14).
