A vibration damper with an adjustable damping force may comprise an inner cylinder having at least one working chamber, an outer cylinder that surrounds the inner cylinder, and at least one damping valve element that in terms of flow is connected via a flow connection to the working chamber. An adapter sleeve may guide the flow connection, with the adapter sleeve being inserted in the inner cylinder on an internal circumference of the inner cylinder. The flow connection may be guided into the damping valve element by way of a flow opening that is configured in a wall of the inner cylinder.

Disclosed is a shock absorber including: a cylinder which is filled with a working fluid; a piston which is slidably provided in the cylinder and divides an inside of the cylinder into two chambers; a piston rod which is connected to the piston and extends outside the cylinder; a first passage and a second passage through which the working fluid flows due to movement of the piston; a first damping force generating mechanism which is provided in the first passage and generates a damping force; and a second damping force generating mechanism which is provided in the second passage and generates a damping force. The second damping force generating mechanism includes a sub valve provided on one side of the second passage, and a volume variable mechanism that changes a volume of a volume chamber provided in parallel with the second passage.

An apparatus for stabilizing movements of two parts of a body region and/or of a sports device which are movable relative to one another, comprising a receptacle, which can be fixed to a first part of the region and/or device. An active body arrangement with an active body is received movably in the receptacle and can interact with the filling medium. A force transmission body can be fixed to a second part of the same region and/or device for transmitting an external force to the active body. The active body comprises at least one through-opening through which a filling medium in the receptacle can flow. The active body arrangement has a sealing lip for sealing a gap between an inner side of the receptacle and a lateral region of an outer side of the active body arrangement, the sealing lip being arranged on an outer side of the active body.
