A saddle-type vehicle includes a vehicle body frame including a main frame extending obliquely rearward and downward from a head pipe, a down frame extending downward from the head pipe and supporting an engine, and a seat frame extending rearward from the main frame and supporting a riding seat, wherein a front wheel is supported by a front portion of the vehicle body frame via a front fork, and a rear wheel is supported by a rear portion of the vehicle body frame via a swing arm, and a vehicle height adjustment device provided below the seat frame to elastically support the seat frame and configured to adjust a height of the seat frame. The vehicle height adjustment device includes an actuator unit and a cushion unit. The actuator unit is disposed between the cushion unit and the engine.

A suspension for a mower includes a stationary part, a movable part, and at least one cutting unit. The moveable part is connected to the stationary part via a hydraulic actuator such that an actuation of the hydraulic actuator displaces the movable part in relation to the stationary part. Displacement of the movable part includes a vertical component of displacement of the movable part. At least one cutting unit is mechanically connected to the movable part.

A rail brake damper includes a cylinder-piston arrangement. A damping device assigned to the piston comprises at least one damping valve having at least one piston channel, which passes through the piston, connecting the two operating chambers of the cylinder, and a closure element assigned to the piston channel. The closure element is spring pre-loaded with the effect of closing the piston channel and is acted on by the hydraulic pressure which prevails in the operating chamber facing away from the piston rod with the effect of opening the damping valve.

A door component has a damper device with two connection units that can be moved relative to each other for damping a door movement of a door of a vehicle. The damper device contains a magnetorheological fluid, as an operating fluid, and a cylinder unit having a first chamber and a second chamber. The two chambers are separated from each other by a piston which is provided with a damping valve. The damper device has a connection which is constructed for coupling to a drive. The damper device can be moved in an active manner at least from a first position into a second position by the drive which is coupled via the connection.

A vibration damper for a motor vehicle includes a valve block and at least one tube assembly. The tube assembly has at least one inner tube and one outer tube which are arranged coaxially. The valve block is arranged in a fluid-tight manner at one axial end of the tube assembly. At least the outer tube is connected in an integrally joined manner to the valve block, and a ring nut is provided at least on the outer tube. The ring nut transmits a prestressing force, in particular a pressing force, to the at least one inner tube such that the at least one inner tube is connected in a non-positive manner to the valve block.
