Continuously blockable locking device

A continuously blockable locking device comprising:

• a cylindrical first housing forming a work chamber completely filled with a liquid medium, the cylindrical first housing having a closed first end and a second end located opposite the closed end;
• a piston rod arranged coaxial to a center longitudinal axis of the cylindrical first housing, the piston rod being guided out of the second end of the cylindrical first housing in a sealed manner;
• a piston arranged at an end of the piston rod situated in the cylindrical first housing, the piston divides the work chamber into a first work space, through which the piston rod extends and a second work space;
• a second housing configured to be connected to the cylindrical first housing, the second housing forming a valve chamber that is at least partially filled with a liquid medium;
• a first valve assembly arranged in the valve chamber;
• and
• a second valve assembly arranged in the valve chamber,
• wherein the first valve assembly and the second valve assembly are each work force dependent valves,
• whereby a blocking of a flow of the liquid medium locks the piston.
