Abstract
The two working chambers ( ) of a working cylinder ( ) of a hydraulic actuation arrangement may be directly connected with one another via a switchable dual-position valve ( ), if necessary, whereby a resistance-free manual displacement of the components to be actuated is possible to a large extent—regardless of the working cylinder ( ) that is driven by the hydraulic circuit ( ) or also in case of a malfunctioning or a turned-off pressure medium source.
