   Bei Aufhebung des Kolbendruckes treiben die Federn der Bremsbänder das Öl in die   Öl kammer 10   zurück und dieses treibt den Kolben vor sieh her, bis die Kanäle 12 mit den Packungsdurehlässen wieder zur Deckung kommen. Ist beim Bremsen ein   Ölverlust   eingetreten, so fliesst die nötige Ölmenge zum Ausgleich dieses Verlustes aus dem Vorratsbehälter durch das Rohr 17 und die   Packungsdurchlässe,

 durch den Verbindungskanal 9 hindurch ein Ausgleich stattfinden. sobald der Kolben sich in unwirksamer Stellung befindet. Die   Druckvorrichtung   stellt sieh somit auf die richtige Ölmenge ein. Das gleiche tritt ein beim Zusammenziehen der Vorrichtung infolge grosser Kälte. 



   Der Vorteil der erläuterten Bauweise besteht darin, dass die Druckvorrichtung keine Federn und keine   bewegliehen Manschetten   od. dgl. enthält und daher auch nicht mit Spezialöl betrieben zu werden braucht. 



   Es ist   zweckmässig,   die Druckvorrichtung mit einem Unterdruck- oder Überdruckbremszylinder

   When the piston pressure is lifted, the springs of the brake bands drive the oil back into the oil chamber 10 and this drives the piston in front of her until the channels 12 come back to cover with the Packungsdurehlässen. If an oil loss has occurred during braking, the amount of oil required to compensate for this loss flows from the reservoir through the pipe 17 and the packing passages,
 EMI2.1
 a compensation take place through the connecting channel 9. as soon as the piston is in the inoperative position. The pressure device thus adjusts to the correct amount of oil. The same occurs when the device is contracted due to extreme cold.



   The advantage of the construction described is that the pressure device does not contain any springs and no movable cuffs or the like and therefore does not need to be operated with special oil.



   It is useful to equip the pressure device with a vacuum or pressure brake cylinder
