Abstract:
1. A pressure generating device for generating a hydraulic pressure as a result of a tensile or compressive load, comprising: connecting means including a connector connectable to a mechanism for transmitting a mechanical tensile or compressive load; a pressure cylinder; a piston unit extending at least partially and movably in said pressure cylinder, said piston unit, together with said pressure cylinder delimiting a hydraulic chamber filled with hydraulic fluid; a coupling assembly connecting said connecting means to said pressure cylinder or to said piston unit, said coupling means being configured to cause said hydraulic chamber to be pressurized under a tensile load as well as under a compressive load, said coupling assembly including hollow sleeve units, each said sleeve unit forming gripping arms configured, under a tensile load, for coming into engagement with stop shoulders formed on said piston unit or on said pressure cylinder, so that said gripping arms and said stop shoulders form tensile coupling means.
