摘要： The invention relates to a hydraulic circuit for the (sequential) control of two of more hydraulic cylinders, more particularly for opening and closing the folding roof with a vehicle of the cabriolet type, in which the cylinder space under the piston (c,B,A,a) of each piston cylinder device is selectively connectable to a hydraulic pressure source (8) or to a reservoir for hydraulic fluid (9), an additional valve (12) device being provided, by means of which the cylinder space above the piston is also connectable to the pressure source (8) for at least a part of the piston cylinder devices. According to the invention the cylinder spaces above the pistons are hydraulically connected and said additional valve (12) device is constituted by a common electrically operated valve for the piston cylinder devices, by means of which the cylinder spaces above the pistons are jointly connectable to either the pressure source (8) or the reservoir (9).

摘要： A hydraulic circuit for opening and closing of a folding roof. The circuit comprises at least two (pairs of) cylinders, one of which being adapted to open and close the folding roof and the other of which being adapted to lock the roof upon closing. The hydraulic circuit further comprises electrically operated valves provided in the circuit in such a way that the (closing) pressure within the roof cylinder is released rapidly as soon as the front roof edge gets within the catching area of the lock member, after which the lock cylinder will immediately close. This prevents the roof from moving into the closing direction too far, which would involve the tendency of the roof to "spring back" and avoids the chance of "miscatching" by the lock member.
摘要翻译：用于打开和关闭折叠屋顶的液压回路。电路包括至少两个（对）气缸，其中一个气缸适于打开和关闭折叠屋顶，另一个适于在关闭时锁定屋顶。液压回路还包括设置在回路中的电动阀，使得当前车顶边缘进入锁定构件的捕获区域内时，顶缸内的（关闭）压力被快速释放，之后锁气瓶将立即关闭。这样可防止屋顶进入关闭方向太远，这将导致屋顶“弹回”的趋势，并避免了由锁定构件“混入”的机会。
