ABSTRACT:
The hydraulic power transformer has a controllable, non-slip jumpering of the hydrodynamic system with insertion of a torsional vibration damper. The torsional vibration damper exhibits a device that varies the damping based on a liquid pressure acting in the vicinity of the device. This device preferably has a piston, which can be moved by the liquid pressure against a surface, and hence generates a damping.
