SYNCHRONIZING CYLINDER FOR CONTINUOUS EXTRUSION PLANT

The invention relates to a synchronizing cylinder (1), preferably for a continuous extrusion plant. The synchronizing cylinder includes an outer cylinder (10), an inner cylinder (20) accommodated therein and arranged concentrically thereto, a double-acting working piston (41) that is displaceably provided in the inner cylinder, and a bypass device (50) having a bypass valve (52). The working piston (41) subdivides the inner cylinder (20) into two pressure chambers (42) and can be acted upon by both pressure chambers (42) with a hydraulic fluid. The bypass device (50) is designed such that in abypass position of the bypass valve (52), a fluid connection between the two pressure chambers (42) is established via a direct connection, preferably at least one bypass line, and in a working position of the bypass valve (52), no such fluid connection exists. 本发明涉及种同步缸(1)、优选地用于连续压制设备的同步缸，其具有外缸(10)、被引入所述外缸中且与其同心地布置的内缸(20)、在内缸中可移动地设置的、双作用的工作活塞(41)和具有至少个绕行阀(52)的绕行装置(50)，其中，工作活塞(41)将内缸(20)分成两个压力腔(412)并且可被两个压力腔(42)利用液压流体加载，
