    摘要： A shock absorber for a motor vehicle includes a compression stoke valve having one or more deflectable discs mounted on the piston on the rebound chamber side and a rebound stroke valve having one or more deflectable discs mounted on the piston on the compression chamber side. A compression flow passage extends through the piston, opening at one end into the compression chamber and having an opening at the other end into the rebound chamber which is closable by the deflectable disc or discs of the compression stroke valve. A rebound flow passage extends through the piston, opening at one end into the rebound chamber and having an opening at the other end into the compression chamber which is closable by the deflectable disc or discs of the rebound stroke valve. One or both valves further includes a flexible disc positioned between the deflectable disc or discs and the piston and extending partly across the associated passage to leave an opening in the passage. The deflectable disc adjacent the flexible disc has an aperture, and a gap is formed between the aperture in the deflectable disc and the flexible disc in the rest position to allow fluid flow from the associated passage through the opening, gap, and aperture. The flexible disc is sized to be capable of flexing and closing the aperture in the adjacent deflectable disc. The arrangement allows setting of different characteristics for low speed compression strokes when compared to low speed rebound strokes.
