Abstract
A pressure generating device generates a hydraulic pressure as a result of a tensile or compressive load. The device has connections, one of which can be rigidly connected to a frame by way of a mechanism for introducing a mechanical tensile or compressive load, a pressure cylinder and a piston unit extending at least partially and flexibly in the pressure cylinder and bounding a hydraulic chamber filled with hydraulic fluid jointly with the pressure cylinder. The chamber has a simple and inexpensive construction. The connections are connected to the pressure cylinder or the piston unit by way of a coupling device that is configured such that the same hydraulic chamber has pressure applied thereto under tensile load and under compressive load.
