    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: A damping valve device includes an actuator which carries out an axial displacing movement on a sliding sleeve. The sliding sleeve, along with a fixed valve carrier, forms a slide valve which has two flow directions. The slide sleeve is impinged with damping medium on a front side and on a rear side in an incident flow direction, and the front side of the slide sleeve and rear side of the slide sleeve are impinged hydraulically in parallel by damping medium during the incident flow.

    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 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.
