<p>The point operating unit comprises a cylinder-piston unit (5) which is connected to bearings (6). The bearings can be displaced in the axial direction of the piston stroke, and is connected to a fixed substructure for setting a defined central position of the piston stroke and of the driver for the movable frog (1). The driver for the movable frog is connected to the cylinder-piston unit while interconnecting stops (9) that can be displaced in the axial direction.</p> |
