摘要： A shock absorber includes a cylinder and a piston dividing the cylinder in first and second cylinder chambers. The piston includes a first main channel and a first main non-return valve allowing a first main fluid flow from the second to the first chamber; and a second main channel and a second main non-return valve allowing a second main fluid flow from the first to the second chamber. The piston includes a connecting member; a first central member received into the connecting member such that the parts of the first main channel in the connecting member and the first central member are in line; and a second central member including another part of the second main channel and received into the connecting member such that the parts of the second main channel in the connecting member and the second central member are in line.

摘要： A frequency-selective damper valve includes a controlled flow channel providing a fluid connection between a first and second valve sides; a controlled valve assembly in a controlled flow channel; a movable valve body acting on the controlled valve assembly; and a variable volume chamber, the movable valve body interacting with the variable volume chamber such that movement of the movable valve body and a change in volume of the variable volume chamber are interrelated. The variable volume chamber includes an outlet opening, in operation, downstream of the controlled valve assembly and does not include an opening upstream of the controlled valve assembly with respect to a controlled fluid flow in the controlled flow channel, the outlet opening providing a flow resistance.

摘要： A fluid-filled, frequency-dependent damper includes a cylinder connected to a cylinder attachment portion; a piston connected to a piston attachment portion, the piston being displaceable in the cylinder; first and second main chambers; and a throttling member for allowing and influencing a fluid flow between the first and second main chambers within the damper when the cylinder attachment portion and the piston attachment portion move relative to each other.

摘要： A damper valve (100) comprises a controlled flow channel (115) between a valve inlet side (100.1) and a valve outlet side (100.2); a controlled valve (130) provided in the controlled flow channel; a movable valve body (120) acting on the controlled valve so as to change a closing force of the controlled valve; and a control chamber (126). The control chamber comprises a control chamber inlet (125) in fluid connection with the valve inlet side (100.1) upstream of the controlled valve (130); a configuration providing a variable volume of the control chamber, a change in volume of the control chamber acting to cause a movement of the movable valve body (120); and a pressure relief valve (160) to allow a relief fluid flow from the control chamber (126) to the valve inlet side (100.1) bypassing the flow restriction (160.1) of the control chamber inlet (125).

摘要： A shock absorber includes a cylinder; a piston dividing the cylinder into first and second chambers, the piston being movable within the cylinder in inward and outward directions; a first main channel and a first main non-return valve allowing a first main fluid flow from the second to the first cylinder chamber; a second main channel and a second main non-return valve allowing a second main fluid flow from the first to the second cylinder chamber; a comfort channel allowing an auxiliary fluid flow between the first and second cylinder chambers; and a comfort valve providing an open connection for the auxiliary fluid flow through the comfort channel in a rest position of the comfort valve and closing off the auxiliary fluid flow at increasing pressure difference across the comfort valve at either inward or outward movement to influence an auxiliary fluid flow between first and second piston sides.

摘要： A damper valve includes a controlled flow channel between inlet and outlet sides; a controlled valve in the controlled flow channel; a movable valve body acting on the controlled valve to change a closing force of the controlled valve; and a control chamber. The control chamber includes a control chamber inlet in fluid connection with the valve inlet side upstream of the controlled valve; a configuration providing a variable volume of the control chamber, a change in volume of the control chamber moving the movable valve body; and a first flexible wall allowing movement of the movable valve body. The first flexible wall provides an effective surface area against which the fluid pressure in the control chamber acts, the effective surface area decreasing upon movement of the movable valve body outward of the control chamber, the first flexible wall including a flex plate bearing against a curved surface.

摘要： A shock absorber includes a cylinder; a piston movable therein and dividing the cylinder in first and second cylinder chambers; a cylinder attachment for attachment to a first part of a vehicle and connected to the cylinder; and a piston attachment for attachment to a second part of a vehicle and connected to the piston. The piston attachment and cylinder attachment move towards one another on an inward movement and away from one another on an outward movement. The piston includes a first inward channel; a first inward valve to open the first inward channel on inward movement; a first outward channel; a first outward valve to open the first outward channel on outward movement; a second inward channel; a second inward valve to open the second inward channel on inward movement; a second outward channel; and a second outward valve to open the second outward channel on outward movement.
