Abstract: A valve arrangement controls a flow of damping medium in a shock absorber. Pressurized damping fluid acts around a whole circumference of the slidable valve member and the impact of flow forces on the slidable valve member is minimized, which vastly decrease the disturbing axial forces and thereby achieves a more dependable valve arrangement with a reliable operation.

Abstract: A valve arrangement controls a flow of damping medium in a shock absorber. A radial column is provided with an axial failsafe flow such that the fail safe flow is not dependent on the exact axial position of the control valve member for creating the fail safe restriction, and less turbulence arise affecting the axial position of the control valve member. Thereby a valve arrangement is provided which has a more stable and reliable failsafe operation, resulting in a more dependable valve arrangement.

Abstract: A valve arrangement comprising a main valve member being axially movably arranged in a valve housing and arranged to interact with a main valve seat of the valve housing in order to restrict or regulate a pressure in a main fluid flow in response to a pilot pressure acting on the main valve member. A control valve member is axially movable within the main valve member in response to an actuating force acting on the control valve member. A pilot valve member is axially movable within the control valve member, and is arranged to interact with a pilot valve seat of the control valve member to restrict a pilot fluid flow out from a pilot chamber. The pilot valve member is resiliently loaded towards the pilot valve seat relative the main valve member or the valve housing, such that the resilient loading on the pilot valve member is adjustable in response to the actuating force.

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.
