- the present invention is based on the problem of an actuating device of the preceding type described so that a safe adjustment of the track section simultaneous check is possible, whether the track section is in the desired End position, i.e. with a switch tongue in the adjacent or remote position located. Proper functioning should also be ensured if the switch tongue undergoes a change in length due to temperature influence. After all, one should easy maintenance and, if necessary, quick replacement of the piston-cylinder arrangement in the case of e.g. Repairs may be possible.
- the problem is essentially solved in that the cylinder of a slidable relative to this and connected to the connecting element Element is surrounded by the when adjusting the cylinder from one of its end positions the cylinder is taken with a time delay.
- the teaching according to the invention makes it possible to move in this way cover that the cylinder moves along the piston rod without the connecting element like the slide rod is first taken along. Rather it becomes a Track part moved with a time delay.
- This makes it possible to start the cylinder first to get out with a locking and / or monitoring device through which in turn the position of the track part can be monitored. Consequently, the locking and / or Monitoring device initially does not hinder a displacement of the cylinder, which where appropriate, would be the case if synchronized with the cylinder movement from the beginning the slide rod and thus the slide parts would be moved.
- the element surrounds a tube or tube that surrounds the cylinder tube sleeve-shaped central section and from this and relative to this includes displaceable end sections, in particular with the cylinder head interact non-positively, the end portions preferably on the Cylinder heads or their end faces on the cylinder tube side are supported with force.
- This spring preload ensures that first the cylinder in the direction of with respect to this spring-biased middle section over the end portions of the element Section is adjustable to then when the spring is tensioned to the required extent, d. H. is compressed to move the section.
- Connecting element such as a slide rod, each of which e.g. with a locking device a switch tongue or connected to a section of such, with the relative is articulated to the cylinder displaceable central portion such that the Connecting element around at least one parallel to the cylinder longitudinal axis and one perpendicular is movable to this extending axis.
