摘要：
The points-changing device described has a multiplicity of interlinked hydraulic control devices (7) spaced at intervals along the line. A mechanical control device is connected to the first hydraulic cylinder/piston unit (7) which is designed to act as a pump, the swept space (13) in this unit (7) being connected up to the swept spaces (13) of subsequent hydraulic cylinder/piston units (7) such that all pump in the same direction.
