Abstract
In the case of an incorrect polarity of connectors in hydraulic networks, a switching device is provided, and formed with a connector part, a valve body, a switching part displaced axially in the valve body within limits, a base part and a top part. Wherein cooperating annular chambers for the conducting of a working fluid are formed in the region of an inner surface of the valve body and an outer surface of the switching part. Annular surfaces (A, A, A, A) are acted upon with pressurized fluid on the switching part towards the top part and annular surfaces (A, A, A) of the switching part are acted upon towards the base part have a following size relations when there is a permanent fluidic connection of the annular chambers:23>0.51;457;3746;1=224567.
