Abstract
The invention relates to a flow-control valve () for a hydraulic shock absorber. Components of the basic structure of the flow-control valve (I) are an axially movable slide () having a body () and a valve sleeve (), an electromagnetic linear actuator () for axial displacement of the slide () and a fixed guide body () configured as a tube and having an end pin (). The valve sleeve () is guided on the end pin () of the guide body () and cooperates with at least one valve opening () formed in the wall of the guide body () such that the flow cross section of the valve opening () can be altered by axial movement of the valve body (). According to the invention the slide () is provided in a pole tube () fixed on the guide body (). The body () of the slide () is guided with a clearance fit in a bearing ring () attached to a section of the pole tube () surrounding the body ().
