Support cylinder for a self-energizing hydraulic brake

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 of said sleeve units forming gripping arms;
• said pressure cylinder being a cylindrical tube arranged at least partially in one of said hollow sleeve units and having a flange section forming a stop shoulder, which under a tensile load comes into engagement with said gripping arms of said sleeve unit.
