摘要： An adjustable vibration damper includes at least one adjustable damping valve, with a piston at a piston rod that divides a cylinder into a work chamber on the piston rod side and a work chamber on the side remote of the piston rod. The cylinder is at least partially enclosed by an intermediate tube that forms a fluid connection between one of the work chambers and the adjustable damping valve. A hydraulic apparatus is connected to the fluid connection of the one work chamber via a first line and to the other work chamber via a second line.

摘要： An adjustable damping valve device for a vibration damper, includes a main stage valve which is controlled by a pre-stage valve with a pre-stage valve body, which pre-stage valve can be actuated by an electromagnetic actuator, wherein an emergency operation valve controls the main stage valve during emergency operation, wherein an emergency operation armature is preloaded on the pre-stage valve body of the pre-stage valve by an emergency operation spring so that the pre-stage valve forms the emergency operation valve.

摘要： An adjustable damping valve device for a vibration damper, includes a main stage valve which is controlled by a pre-stage valve which is functionally connected in series with the emergency operation valve. A pressure relief valve having the constructional form of a seat valve is arranged inside the emergency operation valve and is functionally connected in parallel with the emergency operation valve. A valve body of the pressure relief valve is formed by at least one annular valve disk.

摘要： The disclosure relates to a vibration damper comprising two adjustable damping valve devices, wherein a damping valve device is connected to a piston-rod-side working chamber via a fluid connection and a damping valve device is connected to a working chamber spaced apart from a piston rod within a cylinder filled with damping medium. A fluid connection between the damping valve device and the working chamber occurs via at least one tube element. Both adjustable damping valve devices are connected to a common balancing chamber for receiving the damping medium displaced out of the working chambers by the piston rod. A line block is connected to the cylinder, which forms a first fluid connection to the damping valve device for one of the working chambers and forms an intermediate tube, encasing the cylinder, for a second fluid connection to the damping valve device for the other of the two working chambers. The second fluid connection is also connected to the line block. Both fluid connections have a separate radial channel within the line block, each being connected to an inlet opening of the damping valve devices. A reducer part is arranged between the cylinder and the first fluid line of the line block, and the second fluid line runs within the line block within a projection surface of the cylinder.

摘要： An adjustable vibration damper comprises at least one adjustable damping valve for each working direction. A fluid connection between a compensation space and a working space is controlled by a check valve which has a check valve body and which is hydraulically connected in parallel with the adjustable damping valve. The check valve is held by an intermediate tube which forms the fluid connection and which has a connection orifice to the connected adjustable damping valve. The check valve body of the check valve is supported at least indirectly in the region of the connection orifice.

摘要： An adjustable damping valve device has a first adjustable damping valve assembly for a first flow direction and a second adjustable damping valve assembly for a second flow direction. The two damping valve assemblies are adjustable independently from one another, and the first damping valve assembly generates a damping force for only one flow direction and the second damping valve assembly has a minimum cross section through which damping medium can flow in the setting for maximum damping force so that the second damping valve device generates a damping force in both flow directions.
