    • A piston-cylinder unit, comprising a cylinder which is subdivided by a piston on a piston rod into two working chambers. Between the two working chambers, there is a fluid connection which can be blocked by means of a valve arrangement having at least two individual closing valves arranged in series, each with a valve inflow side and a valve outflow side. The valves open sequentially. In the flow path between the individual valves, there is a throttle arrangement which produces a pressure reduction between the valve outflow side of the first closing valve towards the valve inflow side of the following closing valve. As the opening of the first closing valve increases, the effect of the throttle arrangement decreases; to the same extent, the pressurization increases on the valve inflow side of the following closing valve. The valve arrangement features two flow-through directions and is made so that each can be blocked.
    • 一种活塞缸单元,包括一个由活塞杆上的活塞细分成两个工作室的缸体。 在两个工作室之间,存在流体连接,其可以通过具有至少两个串联布置的各个关闭阀的阀装置来阻塞,每个具有阀流入侧和阀流出侧。 阀门依次打开。 在各个阀之间的流路中,存在节流装置,其在第一关闭阀的阀出口侧朝向下一关闭阀的阀流入侧产生压力降低。 当第一关闭阀的开度增加时,节流装置的作用减小; 在相同的程度上,在随后的关闭阀的阀流入侧的加压增加。 阀装置具有两个流通方向,并且被制成使得每个可以被阻塞。

    • The invention relates to a measuring device, a roll stand and a method for detecting the height of a roll gap between two working rolls in the roll stand. In order to ensure a high level of measurement accuracy of the roll gap transmitter even in the case of horizontal displacement of the working rolls in or against the rolling direction it is proposed in accordance with the invention to carry out adjusting the movement of the roll gap transmitter (110) with respect to the working rolls in the case of a displacement in or against the rolling direction so that even in a new or displaced end position of the working rolls a suitable relative position, which is required for a high level of measurement accuracy, between roll gap transmitter and the working rolls is guaranteed.
