Base valve for two-tubing shock absorber, has control edge provided with plastic or elastomer tool, where elasticity of tool is adjusted such that tool is compressed under load by disk and springs back when opening disk into original form

摘要

The valve has a cylindrically formed valve body (7) provided with passage holes, where the valve body exhibits a circulating control edge (14) in an area of a front surface. The control edge is provided with a rear-ductile plastic or elastomer tool (15) turned to a valve reversal disk, where the elasticity of the plastic or elastomer tool is adjusted such that the tool is compressed under load by the valve reversal disk and springs back when opening the valve reversal disk into original form.
