    摘要： The present disclosure relates to a valve arrangement (1) for improved high frequency performance. The valve arrangement (1) comprises: a valve seat member (2) adapted in size and shape to define a valve seat (21) and a flow-through opening (20); a valve member (3) adapted to be displaceable relative the valve seat (21) along a displacement axis (A) during use in response to a damping fluid pressure force overcoming an opening force threshold, wherein said damping fluid pressure force is provided by damping fluid pressure acting on an inlet side of the valve member (3), said opening force threshold being at least partly adjustable by means of a force actuator (9), wherein the valve member (3) and the valve seat member (2) are adapted to provide a chamfer restriction (22, 32) provided with an opening crosssection which decreases from an inner lateral position to an outer lateral position relative the displacement axis (A). A shock absorber (1000A, 1000B) comprising said valve arrangement (1) and a method for adjusting damping fluid flow is disclosed also.

    摘要： A shock absorber (10) for a motorcycle, comprising:
    - a first coupling element (11), arranged at a first longitudinal end (12) of said shock absorber (10),
    - a head (13) proximate to the first coupling element (11),
    - a first tubular element (14) extending from the head (13),
    - a second tubular element (15) extending from the head (13), concentric to the first tubular element (14) and internal to it, the second tubular element (15) forming at least one chamber (16, 17, 18) for a working fluid,
    - a first stem (19), which can slide within the second tubular element (15), the first stem (19) passing through the head (13),
    - a pumping assembly (20), which can slide within the second tubular element (15) and is at least partially interposed between the first stem (19) and the second stem (21),
    - the second stem (21), which can slide within the second tubular element (15),
    - a bottom (22), crossed by the second stem (21),
    - a second coupling element (23), arranged at the end of the second stem (21) that is opposite to the end adjacent to the pumping assembly (20), the second coupling element (23) being arranged at a second longitudinal end (24) of the shock absorber (10),
    - at least one compensation chamber (25) for the working fluid, in fluidic connection with the at least one chamber (16, 17, 18) of the working fluid, the compensation chamber (25) being arranged within the footprint defined:
    - longitudinally by the distance between the first coupling element (11) and the second coupling element (23),
    - radially by the first tubular element (14).

    摘要： The present application relates to an insert arrangement (1) for engaging with a solenoid arrangement (50) and for closing a valve cavity (60) of a damping arrangement. The insert arrangement (1) comprises: an armature member (20) adapted in shape and size to provide a base portion (21) and an axial portion (22) extending out of the base portion (21) in a direction parallel to a first axis (A), a casing member (10) adapted to extend around the axial portion (22) to define a receiving space between the axial portion (22) and the casing member (10). The solenoid arrangement (50) is at least partly arrangeable in said receiving space, and the casing member (10) is further adapted with a magnetically conducting material for substantially closing a magnetic field generated by the solenoid arrangement (50). The insert arrangement (1) further comprises fixating means (11) for fixating the armature member (20) to the damping arrangement, wherein said fixating means (11) are arranged on the casing member (10).
