Abstract

Die Erfindung betrifft ein Sperrventil, das in mindestens einem Verbraucherkanal eines mit einem Längsschieber ausgestatteten Wegeventils angeordnet ist und in Rückströmrichtung sperrt. Im Körper des Sperrventils sitzt ein ebenfalls in Rückströmrichtung sperrendes Hilfsventil, das zur Einleitung der verbraucherseitigen Verbraucherkanalentlastung über einen vom Längsschieber betätigten Stößel geöffnet wird. Im oder am Sperrventilkörper ist neben dem Hilfsventil ein Druckbegrenzungsventil angeordnet, daß dann öffnet, wenn im verbraucherseitigen Druckmittelstrang der erforderliche Arbeitsdruck um ein vorgegebenes Maß überschritten wird.
