Abstract
A control valve device for a regulation of damping characteristics, in particular of shock absorbers, includes a valve slide and a hydraulic fail-safe unit which is configured, in a de-energized operation state, to provide a fail-safe damping characteristic of the valve slide, the damping hardness of which in a rebound direction lies between a minimally possible rebound damping hardness and a maximally possible rebound damping hardness, and the damping hardness of which in a compression direction lies between a minimally possible compression damping hardness and a maximally possible compression damping hardness.

A control valve device for a regulation of damping characteristics, comprising a valve slide and comprising a hydraulic fail-safe unit which is configured, in a de-energized operation state, to provide a fail-safe damping characteristic of the valve slide, a damping hardness of which in a rebound direction lies between a minimally possible rebound damping hardness and a maximally possible rebound damping hardness, and/or the damping hardness of which in a compression direction lies between a minimally possible compression damping hardness and a maximally possible compression damping hardness, wherein the valve slide comprises at least one hydraulic effective surface and at least one further hydraulic effective surface, wherein the hydraulic effective surface and the further hydraulic effective surface are arranged on the valve slide relative to each other in such a way that they hydraulically counteract each other, wherein in order to generate the fail-safe damping characteristic, the hydraulic fail-safe unit comprises a hydraulic effective sub-surface which is at least hydraulically connectable to one of the hydraulic effective surfaces.
