  • Patent number: 11592074
    Abstract: A shock absorber including a damper and a valve assembly for throttling fluid flow between a compression damper chamber and a pneumatic spring, with a valve assembly extending from an inner end portion of the damper into the compression damper chamber along a longitudinal central axis of the damper. A piston assembly is provided that includes an inner space which is open to the compression damper chamber and configured to receive and sealingly engage a distal portion of the valve assembly at an inner operational range of stroke and to disengage the valve assembly upon movement outside the inner operational range of stroke. The sealing engagement between the distal portion of the valve assembly and the inner space divides the compression damper chamber into an inner volume within the inner space and an outer volume in front of the piston assembly.

  • Patent number: 9409588
    Abstract: A device adjusts the rotational damping of a steering device such that the rotational damping varies depending on whether the rotational motion about a steering axis is caused by a force acting on the steering device of the vehicle or a force acting on the part(s) of the vehicle contacting the ground. The flow of hydraulic fluid in the steering damper partly or wholly is adjusted by a main valve unit that is coupled together with both an attaching part and a steering device. The opening area of the main valve unit is determined by a relative motion between the attaching part and the steering device such that the flow of the hydraulic fluid in a direction from and to the respective damping chambers of the steering damper is controlled depending on the cause of the rotational movement.
