摘要: A hydraulic closing unit has a ring-shaped cylinder (26) that generates force, locking bushing (34), an assisted drive (37) for swivelling the (34) from first angular position to second position, and pressure bar (22) extends through in axial direction. Outer teeth (40) on inner (46) allow be axially pushed of force transmitted (34). The is designed as double action, compression cylinder. piston (28) secured against rotation screwed by means rotary thread (36) into
