Abstract

Eine Anordnung zur hydraulischen Betätigung einer Abdeckklappe (1) an einem Fahrzeug (2) weist einen Arbeitszylinder (3) auf, dessen Arbeitsräume (8, 9) über je ein Rückschlagventil (10, 11) mit jeweils einer Seite einer umschaltbaren Druckquelle (12) in Verbindung stehen. Die beiden Rückschlagventile (10, 11) weisen eine gegenseitige Entsperreinrichtung auf und die beiden Arbeitsräume (8, 9) sind parallel zu den Rückschlagventilen (10, 11) über ein Vorspannventil (15) verbunden. Um auf einfache Weise eine sichere Notbetätigung der Abdeckklappe (1) zu ermöglichen ist zwischen kolbenseitigem Arbeitsraum (8) und entsperrbarem Rückschlagventil (10) ein zum Tank (16) absteuerndes Notventil (17) eingeschaltet, das im Normalbetrieb der Anordnung abgesperrt ist.

Figure 00000001
An arrangement for the hydraulic actuation of a cover flap (1) on a vehicle (2) has a working cylinder (3), the working spaces (8, 9) of which each have a check valve (10, 11) with one side of a switchable pressure source (12). keep in touch. The two check valves (10, 11) have a mutual unlocking device and the two working spaces (8, 9) are connected in parallel to the check valves (10, 11) via a preload valve (15). In order to enable a safe emergency actuation of the cover flap (1) in a simple manner, an emergency valve (17) which shuts off the tank (16) and which is shut off during normal operation of the arrangement is switched on between the piston-side working chamber (8) and the unlockable check valve (10).
