Vibration damper having two adjustable damping valve devices

A vibration damper comprising:

• a cylinder in which an axially movable piston rod with a piston;
• first and second adjustable damping valve devices,
• wherein the piston divides the cylinder into first and second working chambers;
• wherein the first damping valve device is connected to the first working chamber on a piston rod side via a first fluid line, and wherein the second damping valve device is connected to a second working chamber remote from a piston rod disposed inside the cylinder filled with a damping medium;
• wherein the first fluid line between the first damping valve device and the first working chamber is constructed as an intermediate tube;
• and
• both first and second adjustable damping valve devices are connected to a common balancing chamber for receiving the damping medium displaced from the first and second working chambers by the piston rod;
• wherein a line block is connected to the cylinder and forms a second fluid line to the second damping valve device for the second working chamber,
• wherein the intermediate tube encases the cylinder to form an annular chamber between the intermediate tube and an outer casing surface of the cylinder and forming a portion of the first fluid line to the first damping valve device for the first working chamber,
• wherein the first fluid line is also connected to the line block, and wherein the first and second fluid lines each have a separate radial channel inside the line block which is connected to a respective inlet opening of the first and second damping valve devices;
• wherein a reducing piece is arranged between the cylinder and the first fluid line of the line block, and the second fluid line runs inside the line block within a projection surface of the cylinder;
• and
• wherein a length portion of the first fluid line receives the reducing piece and has the radial channel of the first fluid line in connection with a port connector to the first damping valve device for the first working channel.

A vibration damper comprising:

• first and second adjustable damping valve devices,
• a piston rod, and
• first and second fluidic connections;
• wherein the first damping valve device is connected to a first working chamber on a piston rod side via the second fluidic connection, and the second damping valve device is connected to a second working chamber remote from the piston rod, inside a cylinder filled with a damping medium,
• wherein the second fluidic connection between the first damping valve device and the first working chamber takes place via at least one tube element, and both first and second adjustable damping valve devices are connected to a common balancing chamber for receiving the damping medium displaced from the first and second working chambers by the piston rod,
• wherein a line block is connected to the cylinder and forms the first fluidic connection to the second damping valve device for the one of the working chambers, and forms an intermediate tube encasing the cylinder for the second fluidic connection to the first damping valve device for the first working chambers,
• wherein the second fluidic connection is also connected to the line block, and the first and second fluidic connections each have a separate radial channel inside the line block which is connected to a respective inlet opening of the first and second damping valve devices,
• wherein a reducing piece is arranged between the cylinder and the first fluidic connection of the line block, and the second fluidic connection runs inside the line block within a projection surface of the cylinder, and
• wherein the cylinder is encased by a container tube, wherein the container tube has a greater outer diameter in a region congruent with the cylinder than in a region congruent with the line block.
