Abstract

The present invention relates to, among other things, a rotational damper comprising a fluid-filled damper housing and within the damper housing a piston rotatably accommodated by a rotation axis of the rotational damper in a first direction and an opposite second direction with a piston rod extending in the direction of the rotation axis; whereby the piston has at least one opening with a flow cross-section which allows for the flow of fluid through the piston, whereby a total flow cross-section is calculated as the sum of the flow cross-sections of the at least one opening. A blocking device can be furthermore assigned to the piston which is capable of reducing the flow cross-section of at least one of the openings during a rotation of the piston in a first direction relative to a rotation of the piston in the second direction.
