A door component has a controllable damping device containing a magnetorheological fluid as a working fluid. Two connection units can move relative to one another. One of the two connection units can be connected to a support structure and the other of the two connection units can be connected to a moveable door unit of a vehicle in order to damp a movement of the door unit between a closed position and an open position under control of a control device. The damping device has an electrically adjustable magnetorheological damping valve which is current-less in its adjusted state. A damping property of the damping device is continuously adjusted as needed via an electrical adjustment of the damping valve.

The invention relates to an continuously variable locking system for a cylinder-piston arrangement having a cylinder, which has a cap and a base, a piston, which is arranged displaceably in the cylinder and has at least one annular piston seal arranged on the outer surface in the circumferential direction, on which piston a piston rod is arranged, which can be pushed at least partially out axially at the cap end of the cylinder, a closing part, which is continuously variable between an open and a closed position, and a fluid disposed in the cylinder. The object of the invention is to develop the locking system such that the system is characterized by a robust and simple construction, is particularly simple to maintain and adapt, while at the same time being highly reliable and precise in operation. To this end the invention proposes that: the cylinder is designed with a double wall having an inner sleeve and an outer sleeve, the piston is disposed in the inner sleeve, a tubular compensating body having seals running respectively in the circumferential direction on its outer and inner surface is displaceably arranged in an annular space between inner sleeve and outer sleeve, the closing part is arranged at the base end of the cylinder and the base end of the inner sleeve can be closed by means of the closing part.

A vehicle suspension apparatus configured for adjusting vehicle height may include a fixing device disposed at a wheel side, provided on an internal peripheral surface along its perimeter with a plurality of fixing grooves; a moving device provided to be rotatable within the fixing device, formed along its perimeter with coupling grooves corresponding to the fixing grooves and coupled such that a shock absorber moves in an up and down direction; a driving device disposed at the fixing device to transmit power; and a drive shaft provided to be rotatable within the moving device and provided with a fixing pin inserted into the coupling groove of the moving device and the fixing groove of the fixing device such that the fixing pin is disengaged from the fixing groove and remains inserted only into the coupling groove when the drive shaft rotates.

There is provided a front fork provided with a plurality of adjusters, while including a spring adjuster. In order to achieve the above object, in a front fork F according to the means for solving the problem of the present invention, a spring adjuster A is rotatably mounted on a position eccentric to a center O of a cap 4 as viewed in an axial direction and includes a screw portion 35 disposed in an outer periphery protruded into a fork main body 1, and a plate P in which the screw portion 35 of the spring adjuster A is screwed to change support positions of a suspension spring S is brought into contact with a case (tubular member) 14a at two points on both sides in a circumferential direction of the normal of the case 14a that passes a mounting center of the spring adjuster A. Accordingly, while being prevented from rotating, the plate P can be downsized and can be disposed so as not to interfere with first and second adjusters 5, 6.

A spring seat, in particular a spring plate for a vibration damper, in particular a vehicle vibration damper, in particular a spring plate for a level adjustment device, in particular a vehicle height adjustment device, may include a spring retaining ring with an internal cross section or an internal cross-sectional area. The spring seat may also include a spring element configured to reduce the internal cross section of the spring retaining ring. The spring element may be configured such that a reduction of the internal cross section is configured to occur in a radial direction. The spring element may further include a tensioning element configured to adjust a spring tension of the spring element.
