Zylinder für Flüssigkeitsautriehe mit Rücksaugeeinrichtung, insbesondere für
Eisenbahnsignalantriebe.
An Zylindern für Flüssigkeitsantriebe insbesondere für Eisenbahnsignale treten im Betriebe durch Undichtigkeiten der Stangenführung im Zylinderdeckel Verluste in der Antriebsflüssigkeit auf. Durch diese dauernden Flüssigkeitsverluste wird mit der Zeit die Betriebssicherheit gefährdet. Eine gute Abdich-

Cylinders for liquid tanks with back suction device, in particular for
Railway signal drives.
Losses in the drive fluid occur on cylinders for liquid drives, especially for railway signals, due to leaks in the rod guide in the cylinder cover. Over time, these permanent liquid losses endanger operational safety. A good seal
EMI1.1
The piston rod in the cylinder cover must have play.
The invention now relates to a device by which the leaks from the stand

back through the tube into the cylinder space.
In the figure, an embodiment of the invention is given. 1 is the cylinder. 2 of the
EMI1.3
allows the leaked liquid to flow back into the cylinder space. At the beginning of the piston movement, the opening 9 is closed by the piston and the connection between the collecting container and the cylinder space is thereby canceled.
EMI1.4
the upper layer of the piston is exposed.
The tube 8 can of course at any other point on the cylinder, e.g. B. can also be performed outside.
PATENT CLAIMS:
1. Cylinder for liquid drives with return device, in particular for railway signals, characterized in that a channel or a pipe is arranged between the collecting container located on the cylinder and the cylinder space. which has an opening that is exposed by the piston at a certain piston position, for the purpose of preventing the step of the
