DAMPING VALVE DEVICE FOR A DAMPER

The invention relates to a damping valve device for a vibration damper, comprising a valve seat having a circumferential annular groove in which a variable-diameter valve element together with a flow guide surface forms a throttle, the throttle being shifted from a flow through point into a throttle point as a function of the flow velocity of a damping medium, the valve element is moved in a delayed manner towards the flow through point by means of a dead time element when the flow rate is reduced, the annular groove forming a first pressure chamber which is connected to a second pressure chamber by means of a switchable throttle connection. 本发明涉及一种用于减振器的阻尼阀装置，其包括带有环绕的环形槽的阀座，在所述环形槽中直径可变的阀元件与导流面一起形成节流部，其中所述节流部根据阻尼介质的流动速度从穿流部位转入到节流部位中，其中，所述阀元件在流动速度减小时借助于停滞时间环节延迟地朝向穿流部位运动，其中所述环形槽形成第一压力腔，所述第一压力腔与第二压力腔通过可切换的节流连接部连接。
