ABSTRACT:
A device for changing the pressure in tires of a motor vehicle. The novel device achieves that the venting of the tires can be performed independent of throttling. The device includes a tire-pressure control valve (1) with a pneumatic connection terminal (8). A control element (10) is chargeable via the pneumatic connection terminal (8). The control element (10) is formed as an actuating piston, for actuation of the valve device, comprised of valve seat (5) and closure body (6), against a restoring force, furnished by a valve spring (7), into the open position by the pressure of the compressed-air source. The device can be retrofitted into the conventional tire-pressure control device systems.
