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 und jeder der Arbeitsräume parallel zu den Rückschlagventilen über ein in den Tank absteuerndes Vorspannventil (15, 16) auf einem bestimmten Druckniveau gehalten ist. Um auf einfache und sichere Weise eine Notbetätigung der Abdeckklappe (1) auch bei den üblichen, auf Kolben- und Stangenseite unterschiedliche Volumina der Arbeitsräume (8, 9) aufweisenden Arbeitszylindern zu ermöglichen, mündet zwischen zumindest einem Arbeitsraum (8, 9) und dem zugehörigen entsperrbaren Rückschlagventil (10, 11) eine zum Tank (17) führende, separate Nachsaugleitung (23) ein, in welche ein zum Arbeitsraum (8) hin öffnendes Rückschlagventil (24) eingesetzt ist.

The invention relates to an arrangement for the hydraulic actuation of a boot lid, a cover flap or the like (1) on a vehicle, with at least one double-acting hydraulic working cylinder (3) which is articulated on the one hand on the vehicle and on the other hand on the cover flap and its working spaces (8 , 9) are each connected to one side of a switchable pressure source (12) via a non-return valve (10, 11), the two non-return valves having a mutual unlocking device and each of the working spaces parallel to the non-return valves via a pre-load valve in the tank ( 15, 16) is kept at a certain pressure level. In order to enable an easy actuation of the cover flap (1) in a simple and safe manner even in the case of the usual working cylinders (8, 9) with different volumes on the piston and rod side, flows between at least one working space (8, 9) and the associated one Unlockable check valve (10, 11) into the separate suction line (23) leading to the tank (17), into which a check valve (24) opening towards the working space (8) is inserted.
