Abstract: A valve arrangement comprising a valve housing, a pilot chamber, a main valve member and a control valve member. The main valve member is axially movably arranged in the valve housing and is arranged to restrict a main fluid flow. The control valve member is movable in an axial direction relative the main valve member in response to an actuating force acting on the control valve member. The control valve member is arranged to interact with the main valve member to define axially separated pilot and bypass fluid restrictions. The pilot restriction restricts a pilot fluid flow out from the pilot chamber. The bypass restriction restricts a bypass flow bypassing the main fluid flow. The bypass flow is separate from the pilot fluid flow. The pilot and bypass restrictions are adjustable in response to the actuating force, thereby allowing simultaneous adjustment of the pilot pressure and the bypass fluid flow.

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.

Abstract: The present invention provides a hydraulic shock absorber. A solid main piston is designed to slide in a damping cylinder parallel to the movement generated when the shock absorber is subjected to a compression or a rebound stroke, the main piston dividing the damping cylinder into a first damping chamber containing the piston rod and a second damping chamber which does not contain the piston rod. A pressurization reservoir is pressurized by a force acting on a moving piston. The pressurization reservoir is arranged outside the damping cylinder and oriented at an angle relative to the damping cylinder. Two separate, adjustable valves generate a damping force acting in opposition to the stroke movement by restricting a damping medium flow between the damping chambers. A fourth defined chamber is hydraulically connected via separate flow paths to both the first and the second damping chamber and the pressurization reservoir.

Abstract: A vehicle shock absorber generates an additional counter-force acting counter to the direction of movement near the limit position of movement. The shock absorber substantially comprises a damping medium-filled damping cylinder that is divided into two damping chambers by a main piston. The main piston is axially moveable relative to the damping cylinder and is attached to a piston rod. A second piston/damping piston that contains one or more first and second through-ducts is mounted to the piston rod. The ducts are defined by first and second flow-limiting devices such as multiple thin washers. The damping piston slides in a restricting space located in the damping cylinder. The restricting space has an inside diameter smaller than the inside diameter of the damping cylinder. The additional counter-force is substantially constant throughout the entire stroke in order to create gentle braking of the damping movement.

Abstract: The invention relates to a pressurized hydraulic rotation damper intended for use on a multiwheeled vehicle. The rotation damper comprises an outer housing and a lid that together enclose a damping-medium-filled main chamber, which chamber is pressurized by a pressure tank and divided by a delimiting blade/arm into two volumes. The damping medium flows between the two volumes in a duct delimited by at least a first valve and a second valve. These valves throttle the flow between the volumes when the blade moves in an inward and outward motion respectively, starting from an intermediate position where the two volumes are substantially equal in size, to an outer position, in which the blade bears against or is placed close to the inner face of the outer housing. The first valve controls the flow for outward motions and the second valve is used to control the flow for inward motions to either pass through the first valve, through the second valve or through both valves.

The pressure regulator (1) comprises an axially movable first valve part (4) and a first seat (3), which are arranged in a valve housing (2) in such a way that an adjustable flow opening is created between the parts (3, 4).

The spring arrangement comprises a first spring (5) having a first spring constant (k1) and a second spring (6) having a second spring constant (k2).

The solenoid armature rod can have one or more holes that fluidly interconnect a first chamber to a solenoid chamber of the regulator. The delimiting part can be arranged around the solenoid armature rod adjacent to the housing and be configured such that clearances between the delimiting part, the solenoid armature rod, and the housing enable a certain radial movement between the driver and the housing.

Abstract: A pressure regulator adjusts the pressure of a flow of damping medium in a shock-absorber valve (1) between an upstream and downstream volume at first and a third pressures. The pressure regulator comprises a first valve member (3) which moves axially with a stroke, from a seat part (2) with a first side (2a) having at least a first and a second seat (4, 5). When the valve member (3) moves from the seat part, a stroke-varying opening throttling the flow is created between the parts. The seat part comprises at least two parallel first and second throttles (4a, 5a). The seat part also comprises a fixed third throttle (6), arranged in series with the second throttle. The first and second throttle vary with the stroke so that the ratio between the first flow (through first throttle) and second flow (through second and third throttles) increases with the stroke.
