发明名称 Valve device with amplitude-dependent damping force
摘要 <p>The device (1) has a set of bypass channels (49-53) guiding a damping medium to a control area (43), where pressure level of the damping medium influences the damping force of the device. A valve body (21) of a damping valve (33) is attached to the control area, where a back side of the valve body is subjected by the pressure level in the control area. The bypass channels run to the control area through the valve body. A separator piston (59) is arranged in a pressure chamber housing (63), which is fastened to a guiding bolt (37), where the piston is implemented as an annular piston.</p>
