Abstract

Die Erfindung betrifft eine Anordnung zur hydraulischen Betätigung eines Heckdeckels, einer Abdeckklappe od. dgl. (1) an einem Fahrzeug, mit zumindest einem doppeltwirkenden hydraulischen Arbeitszylinder (3), der einerseits am Fahrzeug und andererseits an der Abdeckklappe angelenkt ist und dessen Arbeitsräume (8, 9) über je ein Rückschlagventil (10, 11) mit jeweils einer Seite einer umschaltbaren Druckquelle (12) in Verbindung stehen, wobei die beiden Rückschlagventile eine gegenseitige Entsperreinrichtung aufweisen, jeder der Arbeitsräume parallel zu den Rückschlagventilen über ein in den Tank absteuerndes Vorspannventil (15, 16) auf einem bestimmten Druckniveau gehalten ist und zumindest ein Druckbegrenzungsventil vorgesehen ist. Um auf einfache und sichere Weise die Beschädigung der Anordnung bei manueller Notbetätigung der Abdeckklappe zu vermeiden, setzt zwischen zumindest einem Arbeitsraum (8, 9) und dem zugehörigen entsperrbaren Rückschlagventil (10, 11) eine parallel zum Vorspannventil (15 bzw. 16) zum Tank (17) führende, Leitung (23, 24) an, in welcher das Druckbegrenzungsventil (25 bzw. 26) eingesetzt ist.
