摘要：2.1 In known apparatuses, after the changing of the tyre pressure has ended theclosing process of the tyre pressure control valve is achieved by throttling the airflowfrom the tyre to the tyre pressure control valve. However, such throttling results inrelatively long times for evacuation of the tyre. By means of the new invention it is to beachieved that the emptying of the tyre occurs independently of the aforesaid throttling.…2.2 The new device has a tyre pressure control valve (1) with a pneumatic connection (8)via which an actuation piston (10) for actuating the valve device (5, 6) into the held-openposition counter to a restoring force (7) can be subjected to the pressure of the sourceof the compression means. …2.3 The device can be used in customary tyre pressurecontrol systems.
