Vibration damper
The present disclosure relates to a vibration damper with adjustable damping force, comprising an inner cylinder with at least one working chamber which exhibits a flow connection to a damping-valve device, wherein the damper-valve device is arranged outside of an outer cylinder, wherein the flow connection has been realized in a component that is separate from the inner cylinder, wherein the separate component is constituted by a pressure-stage adapter which constitutes a part of the working chamber and which exhibits a coupling to the damping-valve device, wherein a base piece is arranged at the end of the inner cylinder, wherein the pressure-stage adapter and the base piece have been combined to form a pressure-stage adapter device.
1 . A vibration-damper with adjustable damping force, comprising:
an inner cylinder with at least one working chamber including a flow connection to a damper-valve device, wherein the damper-valve device is arranged outside of an outer cylinder of the vibration damper, wherein the flow connection is defined by a component that is separate from the inner cylinder, wherein the component is defined by a pressure-stage adapter which defines a part of the working chamber and which exhibits a coupling to the damper-valve device, and wherein a base piece is arranged at the end of the inner cylinder such that the base piece closes off the working chamber at the end of the inner cylinder, wherein the pressure-stage adapter and the base piece are combined to form a pressure-stage adapter device;
wherein the pressure-stage adapter device is arranged inside and is surrounded and enclosed by the outer cylinder of the vibration damper at the end of the inner cylinder, such that the base piece is supported at an end of the outer cylinder remote from the piston rod.
2 . The vibration-damper of claim 1 , wherein the pressure-stage adapter device includes a seal.
3 . The vibration-damper of claim 2 , wherein an intermediate pipe encases the inner cylinder in sections, and the seal being arranged between the pressure-stage adapter and the intermediate pipe.
4 . The vibration-damper of claim 1 , wherein the inner cylinder does not exhibit an inner-pipe through-bore for coupling the first damper-valve device.
5 . The vibration-damper of claim 1 , further comprising a pressure-stop damping element within the pressure-stage adapter device.
6 . The vibration-damper of claim 1 , wherein the pressure-stage adapter device includes a connecting pin for accommodating a flange of the damper-valve device.
7 . The vibration-damper of claim 5 , wherein the pressure-stop damping element is attached to the pressure-stage adapter device by a form-closed, force-closed, or substance-closed connection.
8 . The vibration-damper of claim 1 , wherein a seal is arranged between the pressure-stage adapter device and the inner cylinder.
9 . The vibration-damper of claim 1 , wherein the intermediate pipe is configured as a cylindrical intermediate pipe, in particular is configured without widenings/constrictions.
10 . The vibration-damper of claim 1 , wherein the intermediate pipe includes a mantel for coupling the damper-valve device.
11 . The vibration-damper of claim 3 , further comprising an upper separating unit arranged between the intermediate pipe and the inner cylinder, the upper separating unit including two welded-on supporting rings with an O-ring arranged in between them.
12 . The vibration-damper of claim 11 , wherein the upper separating unit is arranged on a side of the intermediate pipe, or of the inner cylinder, facing away from the pressure-stage adapter device.
