Claims (3)

Patentansprüche:Patent claims: 1. Selbsttätiges Prüf-, Füll- und Entlüftungsgerät, insbesondere für Kraftfahrzeugreifen, nach Patent 1 209 900, dadurch gekennzeichnet, daß eine Druckluftverteilereinrichtung (Ventil 5) für wenigstens zwei zu jeweils einem Fahrzeugreifen führende Leitungen (6, 7) die Druckluftzufuhr von einem auf den nächsten Reifen umschaltet, wobei die Umschaltung von einer Kontaktbrücke an der Schalteinrichtung (10) gesteuert wird, über die bei Erreichen des voreingestellten Druckwertes ein Kondensator aufgeladen wird, der sich bei Unterschreiten dieses Druckes über ein die Umschaltung der Druckluftverteilereinrichtung (Ventil 5) bewirkendes Schaltrelais entlädt.1. Automatic testing, filling and bleeding device, especially for motor vehicle tires, according to Patent 1 209 900, characterized in that a compressed air distribution device (Valve 5) for at least two lines (6, 7) each leading to a vehicle tire Compressed air supply switches from one to the next tire, the switchover from one Contact bridge on the switching device (10) is controlled via which when the preset Pressure value a capacitor is charged, which when the pressure falls below this via a switch of the compressed air distribution device (Valve 5) causing switching relay discharges. 2. Gerät nach Anspruch 1, dadurch gekennzeichnet, daß die Druckluftverteilereinrichtung durch ein elektromagnetisch gesteuertes Dreiwegventil (5) gebildet ist.2. Apparatus according to claim 1, characterized in that the compressed air distribution device is formed by an electromagnetically controlled three-way valve (5). 3. Prüf-, Füll- und Entlüftungsgerät nach Anspruch 1, bei dem an der pneumatisch gesteuerten elektrischen Schalteinrichtung ein Nullpunktkontakt vorgesehen ist, der beim Eindringen der Druckluft in die Schalteinrichtung den Prüf- und Füllvorgang ein- und beim Entweichen abschaltet, dadurch gekennzeichnet, daß der Nullpunktkontakt (13, 15) mit dem Schaltrelais der Druckluftverteilereinrichtung verbunden ist und bei geschlossenem Nullpunktkontakt das über den Kondensator erregte Schaltrelais mittels einer auf diesem befindlichen Abwurfwicklung in seine Ausgangsstellung geschaltet wird.3. Testing, filling and venting device according to claim 1, in which on the pneumatically controlled electrical switching device a zero point contact is provided, which when the penetration Compressed air in the switching device switches the testing and filling process on and switches off when it escapes, characterized in that the zero point contact (13, 15) with the switching relay of the compressed air distribution device is connected and when the zero point contact is closed, the switching relay excited via the capacitor by means of a on this located discharge winding is switched to its starting position.
