Door component comprising a controllable damping device

A door component for providing damping to a movable door, the door component comprising:

• a controllable magnetorheological damper device containing a magnetorheological fluid and including two connector units that are movable relative to one another;
• one of said two connector units being connectable to a supporting structure of the door and the other of said two connector units being connectable to the door to effect a controlled damping of a movement of the door at least partially between a closed position and an open position;
• said magnetorheological damper device being disposed to damp relative movement between said two connector units, said magnetorheological damper device including a piston unit and a cylinder unit surrounding said piston unit, said piston unit dividing a cylinder volume in said cylinder unit into two chambers;
• said piston unit having a first one-way valve and said two chambers being fluidically connected to one another by way of a return channel and a magnetorheological damping valve, said return channel and said magnetorheological damping valve forming a one-way circuit through which the magnetorheological fluid flows in one given flow direction through said piston unit from one of the two chambers to the other of the two chambers during a movement of said piston unit in one direction and also during a movement of said piston unit in an opposite direction.
